Chapter 1 Introduction About the MultiSwitch 700; how to use this guide; related guides; software conventions; getting help Welcome to the MultiSwitch 700 Modules User’s Guide. We have designed this guide to serve as a reference for using NetSight Element Manager for the MultiSwitch 700 product, which encompasses the DLM6C-AA chassis and the MultiSwitch 700 modules. The MultiSwitch 700 product encompasses the DLM6C-AA chassis and the MultiSwitch 700 modules.
Introduction • NOTE The DLE32-MA and DLE33-MA modules each provide 24 fixed 10Base-T switch ports (via RJ45 for the DLE32-MA and RJ21 for the DLE33-MA) and one slot for an optional modular interface that can link the chassis to an FDDI, ATM, WAN, or Gigabit Ethernet backbone.
Introduction - The DELHG-UA and DELHL-UA are Gigabit Ethernet modular interfaces, each of which provide a single Gigabit Ethernet connection that fully conforms to the IEEE P802.3z (D3.1) Draft Standard. The DELHG-UA provides a single 1000Base-SX (short-wave) multimode fiber optic SC interface, allowing for link distances of up to 500 meters. The DELHL-UA provides a single 1000Base-LX (long-wave) single mode/multimode fiber optic SC interface, allowing for link distances of up to 3 kilometers.
Introduction • Support for redundant, load-sharing power supplies to provide fault tolerance. • Diagnostic LEDs for quick visual diagnosis of interface and device performance; a single removable fan tray; a 19" footprint for ease of installation in rack mounts; and front panel accessibility to all chassis components for easy maintenance.
Introduction monitoring the module’s system resources, finding a source address on the module, establishing module-level port priorities, setting up broadcast suppression on the device, and configuring the module’s front panel COM port and any attached Uninterruptable Power Supply (UPS). Also described in this chapter is the Device View functionality associated with the DELHW-UA modular interface.
Introduction Remote Monitoring (RMON) User’s Guide Alarm and Event Handling User’s Guide For more information about the capabilities of the MultiSwitch 700, consult the appropriate hardware documentation. Software Conventions NetSight Element Manager’s device user interface contains a number of elements which are common to most windows and which operate the same regardless of which window they appear in.
Introduction Device Name Displays the user-defined name of the device. The device name can be changed via the System Group window; see the Generic SNMP User’s Guide for details. IP Address Displays the device’s IP (Internet Protocol) Address. This will be one of two addresses: • The Network IP address assigned to the MultiSwitch 700 chassis (if a network-level IP address has been assigned to the module). • The individual module IP address (if IP addresses have been assigned on a per-module basis).
Introduction Left Mouse Button Right Mouse Button Figure 1-2. Mouse Buttons For many mouse operations, this document assumes that the left (primary) mouse button is to be used, and references to activating a menu or button will not include instructions about which mouse button to use. However, in instances in which right (secondary) mouse button functionality is available, instructions will explicitly refer to right mouse button usage.
Introduction Using Buttons The Cancel button that appears at the bottom of most windows allows you to exit a window and terminate any unsaved changes you have made. You may also have to use this button to close a window after you have made any necessary changes and set them by clicking on an OK, Set, or Apply button. An OK, Set, or Apply button appears in windows that have configurable values; it allows you to confirm and SET changes you have made to those values.
Introduction Accessing On-line Documentation The complete suite of documents available for NetSight Element Manager can be accessed via a menu option available from the primary window menu bar: Help —> Online Documents. If you chose to install the documentation when you installed NetSight Element Manager, this option will launch Adobe’s Acrobat Reader and a menu file, which provides links to all available documents.

The MultiSwitch 700 Device View Port status view options are: Status You can view four port status categories, as follows: • • • • Bridge — FWD, DIS, LRN, LIS, BLK, or BRK Bridge Mapping — the instance of the physical interface associated with a bridge port Admin — ON or OFF Operator — ON or OFF If you have selected the Bridge status mode, a port is considered: • FWD (Forwarding) if the port is on-line and ready to forward packets across the MultiSwitch 700 from one network segment to another.
The MultiSwitch 700 Device View If you have selected the Operator status mode, a port is considered: • ON if the port is currently forwarding packets. • OFF if the port is not currently forwarding packets. Note that the Operator status provides the actual status of the port; depending on the circumstances, this may or may not reflect the Admin state currently requested by management.
The MultiSwitch 700 Device View Port Status Color Codes Three of the Port Status display options — Bridge, Admin, and Operator — incorporate their own color coding schemes: for the Bridge option, green = FWD, blue = DIS, magenta = LIS or LRN, orange = BLK, and red = BRK; for Admin and Operator, green = ON, red = OFF, and blue = N/A (not available).
The MultiSwitch 700 Device View From the Backplane View you can display the device interfaces with respect to their bridging status or their MIB II Interface status. The currently selected Port Display Form is shown in the label above the interfaces. Below the Port Display Form label, the interfaces appear according to the currently selected Display Form. In the Bridge display form, you can access management options for the individual interfaces.
The MultiSwitch 700 Device View The backplane connections are indexed 1–5, where 1 indicates the connection to first slot in the chassis and 5 indicates the connection to the last slot. Backplane View Bridge Display Form When the Backplane View display form is in the default Bridge mode, each connection is represented by a color-coded text field as follows: FWD (Green) The interface is on-line and ready to forward packets across the MultiSwitch 700 from one module to another.
The MultiSwitch 700 Device View ON (Yellow) The backplane interface is operational (up) and administratively enabled; however, the interface link status is Not Linked (NLK). OFF (Blue) The interface is not operational, and prior to going down it was also administratively disabled. OFF (Red) The interface is not operational, but prior to going down it was in an administratively enabled state. TEST (Magenta) The interface is in some test operational state.
The MultiSwitch 700 Device View The MIBs which provide the MultiSwitch 700’s functionality — both proprietary MIBs and IETF RFCs — are listed here. MIB Components are listed here; remember, there’s no one-to-one correspondence between MIBs and MIB Components. Figure 2-6. The Chassis Manager Window The Module Information Window The Module Information window (Figure 2-7) displays system information, as well as data provided by the PIC chip (Product Information Chip).
The MultiSwitch 700 Device View Firmware Version The system description of the module, including its firmware revision number. Boot Prom The revision of boot PROM firmware in the module, including major version number and minor revision number. The boot PROM provides power-on diagnostics and download capability which enables the module’s system image (which provides its runtime functionality) to be downloaded over the network.
The MultiSwitch 700 Device View 2. Select Module Type. A Module Type text box (similar to the example shown in Figure 2-9) opens, describing the module type. Figure 2-9.

From the Device View, click on the Device option from the menu bar. 2. Click again to select I/F Summary.
The MultiSwitch 700 Device View Description A text description of the interface: e.g., Ethernet Frontpanel (for the standard Ethernet front panel interfaces), Fast Ethernet (for front panel Fast Ethernet interfaces), FTM Backplane (for the backplane interfaces to the chassis), Host or Host Data Port for the on-board i960 Host interface, and ATM, or FDDI, for an installed modular interface. Physical Status Displays the current physical status — or operational state — of the interface: Online or Offline.
The MultiSwitch 700 Device View In Discards Packets received by the device interface that were discarded even though no errors prevented them from being delivered to a higher layer protocol (e.g., to free up buffer space in the device). In Errors Packets received by the device interface that contained errors that prevented them from being delivered to a higher-layer protocol. In Unknown Packets received by the device interface that were discarded because of an unknown or unsupported protocol.
The MultiSwitch 700 Device View Viewing Interface Detail The Interface Statistics window (Figure 2-13) provides detailed MIB-II interface statistical information — including counts for both transmit and receive packets, and error and buffering information — for each individual port interface. Color-coded pie charts also let you graphically view statistics for both received and transmitted Unicast, Multicast, Discarded, and Error packets. To open the Interface Statistics window: 1.
The MultiSwitch 700 Device View Type Displays the interface type of the selected port: ethernet-csmacd, fddi, or atm. The lower portion of the window provides the following transmit and receive statistics; note that the first four statistics are also graphically displayed in the pie charts. Unicast Displays the number of packets transmitted to or received from this interface that had a single, unique destination address. These statistics are displayed in the pie chart, color-coded green.
The MultiSwitch 700 Device View Making Sense of Detail Statistics The statistics available in this window can give you an idea of how an interface is performing; by using the statistics in a few simple calculations, it’s also possible to get a sense of an interface’s activity level: To calculate the percentage of input errors: Received Errors /Packets Received To calculate the percentage of output errors: Transmitted Errors /Packets Transmitted To calculate the total number of inbound and outbound discards
The MultiSwitch 700 Device View The Device Find Source Address window can be accessed from the Chassis View menu or the Module Index: From the Chassis View: 1. Select Device—>Device Find Source Address. From the Module Index: 1. Click on a module index to display the Module menu and select Device Find Source Address. The Device Find Source Address window, as shown in Figure 2-14, opens. Figure 2-14.
The MultiSwitch 700 Device View NOTE If you enter the MAC format of a specified address, and then click on Canonical, NetSight Element Manager will do the address conversion for you, from the Ethernet hexadecimal format to the Token Ring Canonical format. The same is also true if you enter the Canonical format of a specified address and then select MAC. 3. Click on the Find It! button. A “Processing Request” message displays in the status bar at the bottom of the window.
The MultiSwitch 700 Device View Ethernet and Gigabit Ethernet Port Configuration windows are available from the Device View Port menus; the COM Port option is available from the Device menu. Note that no configuration option currently exists for ATM ports. Configuring Standard Ethernet and FDDI Ports The Port Configuration window available for both standard Ethernet and FDDI ports allows you to set an interface to either Standard or Full Duplex Mode.
The MultiSwitch 700 Device View WARNING For standard Ethernet interfaces, Full Duplex should only be enabled on an interface that has a connection to a single destination address at the other end of the connection (i.e., it is not a segment with an attached repeater cascading the connection to multiple destination addresses). Full Duplex mode disables the collision detection circuitry at the interface, so that both Transmit and Receive wires can be used simultaneously.
The MultiSwitch 700 Device View configured to operate in Full Duplex, effectively doubling the available wire speed (from 10 to 20 Mbps in standard Ethernet mode, or from 100 to 200 Mbps in Fast Ethernet mode); 100Base-FX (fiber) ports can be configured to operate in their standard 100 Mbps mode, or in Full Duplex mode. This window also displays the mode currently in effect on the selected interface, and provides some information (where it is available) about the interface’s link partner.
The MultiSwitch 700 Device View TIP If you select the Configuration option available for a standard Ethernet or FDDI interface or for a Fast Ethernet port on a second generation module, an entirely different window displays; see Configuring Standard Ethernet and FDDI Ports, on page 2-30, or Configuring Ethernet Ports on Second Generation Modules, on page 2-36, for information on configuring these ports.
The MultiSwitch 700 Device View ! CAUTION If you choose to select a specific mode of operation (rather than auto-negotiation), you should be sure that the link partner supports the same mode. Otherwise, no link will be achieved. If you select a Full Duplex mode and the link partner supports the same wire speed but not Full Duplex, a link will be achieved, but it will be unstable and will behave erratically.
The MultiSwitch 700 Device View • Link Partner does not support Auto-Negotiation — Auto-Negotiation is either not supported by or is not currently selected on the remote port. • Unknown — the link partner’s capabilities could not be determined. When the local node is not set to Auto-Negotiation, this field will be grayed out, even if the link partner is set to Auto-Negotiation and is advertising abilities.
The MultiSwitch 700 Device View 100Base-TX Full Duplex — 100 Mbps connection, Duplex Mode For 100Base-FX ports, options are: 100Base-FX — 100 Mbps connection, Standard Mode 100Base-FX Full Duplex — 100 Mbps connection, Duplex Mode 2. If you have selected Auto-Negotiation (for 100Base-TX ports only), use the Advertised Abilities field to select the operational capabilities you wish to advertise to the port’s link partner.
The MultiSwitch 700 Device View To access the Ethernet Configuration Window: 1. Select the port you wish to configure; the Port Menu will display. 2. Click Configuration. The Ethernet Configuration window, Figure 2-16, opens. Figure 2-17.
The MultiSwitch 700 Device View The window displays the following information about the selected Ethernet port: Port Type Displays the port’s type: 100Base-TX RJ-45or RJ71 (for built-in Fast Ethernet ports and the FE-100TX Fast Ethernet port module), 100Base-FX MMF SC Connector (for the FE-100FX Fast Ethernet port module), 1000Base-SX/LX/CX (for the VHSIM-G6 Gigabit Ethernet port module), or Unknown (for a port slot with no module installed).
The MultiSwitch 700 Device View The Current Operational Mode settings indicate which of the available operational modes is currently in effect. If Auto Negotiate is the selected mode, the Current Operational Mode fields will indicate which mode was selected by the link partner. The Desired Operational Mode settings display the operational mode that is currently selected for this port, and allows you to change the selection.
The MultiSwitch 700 Device View Setting the Desired Operational Mode For any 100Base-TX port, you can configure operational modes, or you can select Auto Negotiate mode, which allows the port to negotiate with its link partner to find the highest mutually available bandwidth and flow control. If you select Auto Negotiate mode, you must also choose which of the port’s bandwidth and flow control capabilities you wish to advertise to the link partner (refer to Auto Negotiation Technologies, page 2-40).
The MultiSwitch 700 Device View TIP If you select Auto-Negotiation at both ends of a link, be sure at least one mutually-advertised operational mode is available. If you have manually configured specific operational modes for your 100Base-TX port or if you are configuring a 100Base-FX port, the Auto Negotiation Technologies list box does not apply.
The MultiSwitch 700 Device View Configuring the COM Port You can use the COM Port Configuration window (Figure 2-18) to specify the functions that will be performed by the RS232 COM port on the front panel of the monitored MultiSwitch 700 module. 1. Click on Device in the Device View menu bar to display the Device menu. 2. Click on COM Port Configuration and then right to select Port 1. The COM Port Configuration window, Figure 2-18, opens. Figure 2-18.
The MultiSwitch 700 Device View PPP NOTE Select this option to use the COM port as a PPP connection for out-of-band SNMP management via direct connection to a serial port on your network management workstation. Note that when you configure the port as a PPP connection, you must select the desired baud rate in the Speed Selection field described below. Current MultiSwitch 700 firmware versions support only Local Management and UPS via the COM ports; future versions will add SLIP and PPP support.
The MultiSwitch 700 Device View Accessing the UPS Window At the UPS window, you can configure the UPS ID model type for the uninterruptable power supply you have attached to the COM port on your device.
The MultiSwitch 700 Device View UPS ID Displays the manufacturer and model typecode of the UPS attached to the COM port of the MultiSwitch 700. You must assign this typecode for the UPS window to be active. (See Setting the UPS ID, on page 2-46, for instructions for setting the typecode for your UPS.
The MultiSwitch 700 Device View Setting the UPS ID You need to set the UPS ID typecode that indicates the manufacturer and model of the UPS. To set the UPS ID: 1. Click on next to the SET UPS ID text box. A Model number menu displays. Scroll to highlight the appropriate UPS ID.

The MultiSwitch 700 Device View priority queue. However, the MultiSwitch 700 will tag outgoing frames with the full range of eight priority levels, so that upon reception, a device that supports the entire range of priority queuing will forward the frame appropriately. You can use NetSight Element Manager to configure the criteria that determine the priority in which frames will be queued for transmission by your MultiSwitch 700 module.
The MultiSwitch 700 Device View Highlight a module/port, then use the drop-down list box to select a priority (Normal–7). Click Apply to set the priority at the device. Any priority of 1 or higher will allow packets received at the chosen port to be forwarded from the higher priority transmission queue. Figure 2-21.
The MultiSwitch 700 Device View 2. Click on the Transmit Priority drop-down list box, and scroll to select the desired priority level (Normal–7) for forwarding packets received on the selected port. NOTE Remember, since the MultiSwitch 700 module has two transmit queues, a priority of Normal will cause packets received on that port to be forwarded through the lower priority queue, and any priority of 1 through 7 will cause the packets to be forwarded through the higher priority queue.
The MultiSwitch 700 Device View To access the MAC Based Priority Configuration window: 1. Click Device to access the Device menu. 2. Click Priority Configuration, and then right to select MAC Based from the menu. The MAC Based Priority Configuration window opens.

The MultiSwitch 700 Device View DRAM Available: Displays (in Kbytes) the amount of free DRAM that is not currently being used for data storage. SRAM Installed: Displays the total amount of SRAM (Static Random Access Memory) that is installed (in Mbytes). SRAM retains data as long as the CPU is powered up. Since it does not need the constant recharging of DRAM memory, its data can be accessed much faster.
The MultiSwitch 700 Device View NOTE The default setting for this field is No. While No is selected the peak switch utilization value will not be reset when you click on the Apply button. You must choose Yes for a reset to take place. CPU Management Reservation: Displays the desired amount of CPU bandwidth reserved for management purposes: None, Limited, or Full. Bandwidth that is not reserved for management will be devoted to switching.
The MultiSwitch 700 Device View NOTES NOTE For older versions of MultiSwitch 700 firmware, if 802.1Q is to be utilized it is required that all modules in the chassis be configured to operate in 802.1Q mode. Distributed Chassis Management may not be supported for MultiSwitch 700 modules operating in 802.1Q mode. In such cases, it is recommended that all modules installed in the MultiSwitch 700 chassis be configured via Local Management to operate in Standalone mode.
The MultiSwitch 700 Device View Ports on 802.1Q switches are assigned membership in a VLAN by associating a VLAN ID with each port on the switch. The VLAN ID is combined with the port’s identification (e.g., module X port X) to form the Port VLAN ID (PVID). NOTE When 802.1Q mode is initially activated on a device, all ports are associated with the Default VLAN (VLAN ID 1). If a VLAN ID has not been assigned to a particular port on an 802.
The MultiSwitch 700 Device View If a port receives a tagged frame that specifies a VLAN other than the one assigned to the port, the switch will dynamically associate that frame’s source address and VLAN with the port (i.e., add that frame’s VLAN to the receiving port’s egress list). Dynamically learned VLANs are subject to the same aging rules as source addresses (e.g.
The MultiSwitch 700 Device View ! CAUTION For older versions of MultiSwitch 700 firmware, if 802.1Q is to be utilized it may be required that all modules in the chassis be configured to operate in 802.1Q mode. If you attempt to activate a MultiSwitch 700 module’s 802.1Q component via the Mib Tools application, you may lose contact with the rest of the chassis once the device resets. For this reason, we recommend that Local Management be used to activate 802.1Q mode for MultiSwitch 700 modules.
The MultiSwitch 700 Device View Figure 2-26. The VLAN Config Window The Configured VLANS list box and fields allow you to view, create, modify, delete, enable, and disable 802.1Q port-based VLANs. The list box displays the following information about your defined VLANs: VLAN ID The VLAN ID is used to identify data frames that originate from, and are intended for, the ports assigned to the VLAN. Up to 64 VLANs may be created, with VLAN IDs ranging from 2-4094.
The MultiSwitch 700 Device View Creating and Modifying VLANs The fields immediately below the Configured VLANS list box are used to create and modify your port-based VLANs. To create a new VLAN: 1. In the VLAN ID field, enter a unique value between 2-4094. VLAN ID 1 is reserved for the Default VLAN, and cannot be used. 2. If desired, enter a name for the VLAN in the VLAN Name field. VLAN names must be 32 characters or less.
The MultiSwitch 700 Device View Enabling and Disabling VLANs NOTE Unless Enable is selected when a VLAN is initially defined, it is disabled by default. A new VLAN that is left in a Disabled state will remain disabled until a port is assigned to it, at which time it will be automatically enabled. If you are changing a VLAN’s port assignment, the VLAN should be disabled before changing the port configuration.
The MultiSwitch 700 Device View Figure 2-27. The VLAN Port Config Window The 802.1Q VLAN Port Assignment list box in this window displays the following information about ports on your 802.1Q switch: Slot/Port These fields display the slot and port index for each port on your 802.1Q switch. VLAN ID This field displays the VLAN ID of the VLAN to which the port is currently assigned. Mode This field displays the port’s current mode of operation.
The MultiSwitch 700 Device View • Hybrid mode, which allows a port to receive and transmit both tagged and untagged frames. In this mode, the port will be a member of its statically assigned VLAN, as well as any dynamically learned VLANs. Hybrid mode is enabled by default. For more information on 802.1Q port operational modes, see 802.1Q Port Types, on page 2-63. Discard This field displays the port’s current frame discard format (discardTagged, discardUntagged, or noDiscard).
The MultiSwitch 700 Device View Setting Port Operational Modes To assign a port operational mode (dot1dTrunk, dot1QTrunk, or hybrid) to a port on your 802.1Q switch: 1. In the VLAN Port Config window’s list box, click to select a port to which you wish to assign a port operational mode. 2. In the Port Operational Mode field, click to select the desired operational mode. 3. Click the Apply button. The selected mode will be reflected in the list box for the selected port.
The MultiSwitch 700 Device View Figure 2-28. The VLAN Egress Port Config Window The list box at the top of this window is used to select a configured VLAN for association with your switch’s ports. Clicking on a VLAN will display its currently associated ports in the lower portion of this window. The list box displays the following information: Slot Number This field displays the slot index for the module being configured. VID This field lists the VLAN IDs of the currently configured VLANs on your switch.
The MultiSwitch 700 Device View Under the list box there are two groups of check boxes that display the ports on the switch. A checkmark in the port’s check box indicates that the VLAN selected in the list box is in the port’s egress list. The two groups are: Egress Ports Use these check boxes to add or remove the selected VLAN from the egress list of one or more ports. Egress Untagged List Use these check boxes to allow the ports to transmit untagged frames from the selected VLAN.

Enter the new time in a 24-hour hh:mm:ss format, either by highlighting the field you wish to change and using the up and down arrow buttons, or by entering the new value in the appropriate field. 4. Click OK to save your changes, or Cancel to exit without saving changes. To edit the device date: 1. Click on Device on the Device View menu bar to access the Device menu. 1. Select Edit Device Date.
The MultiSwitch 700 Device View Enabling and Disabling Ports When you disable bridging at a port interface, you disconnect that port’s network from the bridge entirely. The port does not forward any packets, nor does it participate in Spanning Tree operations. Nodes connected to the network can still communicate with each other, but they can’t communicate with the bridge or with other networks connected to the bridge.
The MultiSwitch 700 Device View The DELHW-UA Device View Unlike other modular interfaces designed for the MultiSwitch 700 boards, the DELHW-UA module functions as an independent intelligent device with its own IP address. As such, it must be managed separately from the MultiSwitch 700 chassis and the board on which it is installed. This section provides information on launching the DELHW-UA Device View and using its associated functions.
The MultiSwitch 700 Device View DELST-UI This port interface module provides an ISDN 128 Kbps Basic Rate Interface (BRI) and is designed for an ISDN back-up link for a frame relay or leased line. In the United States and Canada, Network Terminator equipment (NT1) is required to provide an interface between the DELST-UI and the ISDN line. DELSY-UI Provides a synchronous serial connection of up to 2.048 Mbps to external communications equipment (an external CSU/DSU is required).
The MultiSwitch 700 Device View Launching the DELHW-UA Device View Window The DELHW-UA Device View window is the main screen that immediately informs you of the current condition of individual ports on your switch via a graphical display. The Device View window also serves as a single point of access to all other DELHW-UA windows and screens, which are discussed throughout this manual. To access the DELHW-UA Device View window, use one of the following options: 1.
The MultiSwitch 700 Device View Figure 2-31. The DELHW-UA Device View Window NOTES The Device View windows will only display the bridge ports on a DELHW-UA. See your QuickSET for the DELHW-UA documentation for information on managing your Ethernet ports.
The MultiSwitch 700 Device View Front Panel Information The areas surrounding the main chassis area provide the following device information: IP The Internet Protocol address assigned to the DELHW-UA appears in the title bar of the Device View window. IP addresses are assigned via Local Management. Connection Status This color-coded area indicates the current state of communication between NetSight Element Manager and the DELHW-UA.
The MultiSwitch 700 Device View Date The current date, in an mm/dd/yyyy format, set in the DELHW-UA’s internal clock. Menu Structure By clicking on various areas of the DELHW-UA Device View display, you can access menus with device- and port-level options, as well as utility applications which apply to the device.
The MultiSwitch 700 Device View • Edit Device Time/Edit Device Date allows you set the device’s internal clock. See Setting the Device Date and Time, on page 2-72. • System Group allows you to manage the DELHW-UA via SNMP MIB II. Refer to the Generic SNMP Guide for further information. • I/F Summary allows you to view statistics (displayed both graphically and numerically) for the traffic processed by each network interface on your DELHW-UA.
The MultiSwitch 700 Device View • RMON, for launching the Remote Network Monitoring application. RMON is described in its the Remote Monitoring (RMON) User’s Guide. These selections are also available from the Tools menu at the top of NetSight Element Manager’s main window. NOTE You will be able to launch the QuickSET for the DELHW-UA application from the Utilities menu, provided it is installed on your machine. See your QuickSET for the DELHW-UA documentation for more information.
The MultiSwitch 700 Device View • Statistics launches the highest level of statistics currently available for the selected port. For standard Ethernet and Fast Ethernet ports, RMON statistics will be displayed if the RMON Default MIB component is active; if it has been disabled, MIB-II interface statistics will display. See Chapter 3, Statistics, for more information.
The MultiSwitch 700 Device View • BLK (Blocking) if the port is on-line, but filtering traffic from going across the DELHW-UA from one network segment to another. Bridge topology information will be forwarded by the port. • BRK (Broken) if the physical interface has malfunctioned. • UNK (Unknown) if the interface’s status cannot be determined.
The MultiSwitch 700 Device View I/F Speed If you choose the I/F Speed mode, the port text boxes will display the speed of the network segment connected to each port. The speed of the network management port will be displayed in Kbps. I/F Type If you choose the I/F Type mode, the interface boxes will display the interface type of each port on the DELHW-UA (e.g., Eth, PPP, other). Port Status Color Codes The Port Status display options — Bridge, Admin, and Operator — incorporate color coding schemes.

Chapter 3 Statistics Accessing interface statistics from the Device View; available statistics windows Each port menu in the Device Logical View window provides two statistics selections: Statistics and I/F Statistics.
Statistics NOTE If the selected interface displays MIB-II I/F Statistics and you were expecting to see RMON statistics, the RMON Default MIB component may be disabled; see the RMON User’s Guide for information on how to check (and if necessary, change) the admin status of the RMON Default MIB component. RMON Statistics The RMON Ethernet Statistics window (Figure 3-1) provides a detailed statistical breakdown of traffic on the monitored Ethernet network.
Statistics The selected interface number and its description are displayed at the top of the Statistics window. The column on the left side of the window displays each statistic’s name, total count, and percentage; the column on the right displays the peak value for each statistic, and the date and time that peak occurred. Note that peak values are always Delta values; see Viewing Total, Delta, and Accumulated Statistics, on page 3-5, for more information.
Statistics Problems CRC/Alignment Indicates the number of packets processed by the network segment that had a non-integral number of bytes (alignment error) or a bad frame check sequence (Cyclic Redundancy Check, or CRC error). Fragments Indicates the number of packets processed by the network segment that were undersized (less than 64 bytes in length; a runt packet) and had either a non-integral number of bytes (alignment error) or a bad frame check sequence (CRC error).
Statistics Frame Size (Bytes) Packets The Frame Size (Bytes) Packets fields indicate the number of packets (including error packets) processed by the network segment that were of the noted length, excluding framing bits but including frame check sequence bits.
Statistics 3. Click on the Accum option button; after the completion of the current polling cycle plus two more polling cycles, the screen will display a fresh cumulative count of statistics. Note that making this selection does not clear device counters; you can still re-select Total for the total count since the device was last initialized. Switching the statistics displays among Total, Delta, and Accum does not effect the displayed peak values, as peak values are always Delta values.
Statistics Interface Statistics The interface I/F Statistics window (Figure 3-3) provides MIB-II interface statistical information — including counts for both transmit and receive packets, and error and buffering information — for the front panel interfaces on the MultiSwitch 700 module. Color-coded pie charts in the middle of the window let you graphically view statistics for Unicast, Non-Unicast, Discarded and Error packets.
Statistics Three informational fields appear in the upper portion of the window: Description Displays the interface description for the currently selected interface (e.g., Enet, Fast Enet, FDDI, ATM, or Backplane Port). Address Displays the MAC (physical) address of the selected interface. Type Displays the interface type of the selected port: e.g., ethernet-csmacd, fddi, or atm.
Statistics Packets Received (Received only) Displays the number of packets received by the selected interface. Transmit Queue Size (Transmit only) Displays the number of packets currently queued for transmission from this interface. The amount of device memory devoted to buffer space, and the traffic level on the target network, determine how large the output packet queue can grow before the MultiSwitch 700 module will begin to discard packets.
Statistics 3-10 Interface Statistics
Chapter 4 Alarm Configuration Accessing the Basic and Advanced Alarms windows; creating a basic alarm; creating an advanced alarm; creating events; assigning actions to events; viewing the event log Through the RMON Alarm and Event functionality supported by your MultiSwitch 700 module, you can configure alarms and events (and, where appropriate, actions) for each available interface.
Alarm Configuration Using the Advanced Alarms feature, you can define custom alarms for almost any MIB-II or RMON object, as long as it is present in the device firmware and its value is defined as an integer (including counters, timeticks, and gauges).
Alarm Configuration TIP The Basic Alarm Configuration window combines the three parts of creating a working alarm — configuring the alarm itself, configuring an event that will announce the occurrence of an alarm (including assigning any actions), and linking the two — into a single step, and handles the details transparently. For more information about the individual steps involved in creating an alarm, see Advanced Alarm Configuration, on page 4-10.
Alarm Configuration Figure 4-1. RMON Basic Alarm Configuration Window TIP • Total Errors (ifInErrors) — tracks the number of error packets received by the selected interface. • Broadcast/Multicast (ifInNUcastPkts) — tracks the number of non-unicast — that is, broadcast or multicast — packets received by the selected interface.
Alarm Configuration IF Type Displays each interface’s type: FDDI, Ethernet, Token Ring, or ATM. Note that there is no type distinction between standard Ethernet and Fast Ethernet. Status Displays the current status of the selected alarm type for each interface: Enabled or Disabled. Remember, this status refers only to the alarm type which is selected at the top of the window; each of the other two alarm types can have different states.
Alarm Configuration Falling Action These option buttons indicate whether or not a falling alarm occurrence will initiate any actions in response to the alarm condition: Enable Port if bridging will be enabled at the selected interface in response to a falling alarm, Disable Port if bridging will be disabled in response to a falling alarm, or None if no actions have been configured for the selected alarm. The Action fields will be unavailable for devices that do not support the new Actions MIB.
Alarm Configuration 3. In the Interval field, enter the amount of time, in seconds, over which the selected variable will be sampled. At the end of the interval, the sample value will be compared to both the rising and falling thresholds. You can assign any interval from 1 to 65,535. 4. In the Alarm field, click to select one or both of the following options: a. Select Log if you wish to create a silent log of alarm occurrences. b.
Alarm Configuration 7. In the Rising Action field, click to select the action you want your device to take in response to a rising alarm: Enable Port, Disable Port, or None. Note that this action enables or disables only bridging at the specified port, and not the interface itself. For more information on how actions are triggered, see How Rising and Falling Thresholds Work, on page 4-27. 8. Click in the Falling Threshold field, and enter the low threshold value for this alarm.
Alarm Configuration Disabling a Basic Alarm Using the Disable button at the bottom of the window actually performs two functions: it both disables the alarm and deletes the alarm entry (and its associated event and action entries) from device memory to help conserve device resources. In the list box display, the parameters for any “disabled” alarm are automatically reset to their default values. 1.
Alarm Configuration The top portion of the Basic Alarm Log window contains the device information boxes, as well as the Port Number assigned to the interface that experienced the alarm condition and the type of alarm that was triggered; the remainder of the window contains the following information about each alarm occurrence: Index TIP This index number uniquely identifies each occurrence of a rising or falling event.
Alarm Configuration Figure 4-3. The RMON Advanced Alarm/Event List Window NOTES Neither the Alarms or Events list is interface-specific; both will be displayed the same for every interface. Alarms and events which have been configured via the Basic Alarms window are not displayed in and cannot be accessed or edited from the Advanced Alarm/Event List window.
Alarm Configuration The fields in the Alarms Watch display include: 4-12 Index The index is a number that uniquely identifies each alarm. Index numbers are user-defined; you can use any indexing scheme that works for you. These numbers are permanently assigned to their associated alarms; however, index numbers made available by the deletion of existing alarms can be assigned to new alarms, as needed. Indices 2000 to 3999 are reserved and unavailable.
Alarm Configuration The information provided in this screen is static once it is displayed; for updated information, click on the Refresh button. Adding or modifying an alarm automatically updates the list. The fields in the Events Watch display include: Index This is a number that uniquely identifies an entry in the event table; an index number is assigned when an event is created.
Alarm Configuration Creating and Editing an Advanced Alarm The Create/Edit Alarms window (Figure 4-4, page 4-15) allows you to both create new alarms and edit existing ones. When you click on the Create/Edit button in the Alarms Watch list, the Create/Edit Alarms window will display the parameters of the alarm which is currently highlighted in the list. (If no alarms have yet been configured, a set of default parameters will be displayed.
Alarm Configuration Figure 4-4. The RMON Create/Edit Alarms Window 2. In the Owner text box, enter some appropriate text designation for this alarm, if desired; you may want to use the network manager’s name or phone number, or the IP or MAC address of the management workstation, to identify the creator of the alarm. Since any workstation can access and change the alarms you are setting in your MultiSwitch 700 module, some owner identification can prevent alarms from being altered or deleted accidentally.
Alarm Configuration TIP The only thing that determines whether you are modifying an existing alarm or creating a new one is the assignment of the index number; be sure to assign this value appropriately. 4. To select the Variable to be used for your alarm, use the MIB Tree display provided on the right side of the window. (For more information about how to use the MIB Tools utility, see the Tools Guide.
Alarm Configuration in which they reside; for example, if you wish to set an alarm on an object located in an RMON Statistics table, you can determine the appropriate instance by noting the index number assigned to the table that is collecting data on the interface you’re interested in. In the case of the default tables, index numbers often mirror interface numbers; however, if there are multiple default tables per interface, or if additional tables have been created, this may not be true.
Alarm Configuration NOTE If you wish to set an alarm on an object whose instance is non-integral — for example, a Host Table object indexed by MAC address — or on an object with multiple indices, like a Matrix Table entry (which is indexed by a pair of MAC addresses), you must follow certain special procedures for defining the instance. For these OIDs, the instance definition must take the following format: table index.length(in bytes).
Alarm Configuration 7. Since the first sample taken can be misleading, you can use the selections in the Startup Alarm box to disable either the rising or the falling threshold for that sample only. If you would like to exclude the falling alarm, select the Rising option; the first sample taken will only generate a rising alarm, even if the sample value is at or below the falling threshold.
Alarm Configuration 13. Click the Apply button to set your changes. If you have made any errors in configuring alarm parameters (using an invalid value in any field, leaving a field blank, or selecting an alarm variable which is not resident on the device), an error window with the appropriate message will appear. Correct the noted problem(s), and click the Apply button again.
Alarm Configuration Figure 4-5. The RMON Create/Edit Events Window TIP Whether you are modifying an existing event or creating a new one is determined solely by the assignment of the Index number: if you assign a previously unused index number, a new event instance will be created; if you use an existing index number, its associated event will be modified. 2. If you are creating a new event, use the Index field to assign a unique, currently unused index number to identify the event.
Alarm Configuration 3. Click in the Description text box to enter any text description you want to identify the event. This description will appear in the Events Watch portion of the main Advanced Alarm/Event window, and help you distinguish among the events you have configured. 4.
Alarm Configuration NOTES In order for the trap selection to work properly, your MultiSwitch 700 module must be configured to send traps to the management station. This is accomplished via local management or the Remote Administration Tools application; consult your device hardware manual or the Remote Administration Tools User’s Guide for details.
Alarm Configuration To add an action or actions to an event: 1. In the Create/Edit Events window, click on the Actions button. The Create/Edit Action window, Figure 4-6, will appear. Figure 4-6. The RMON Create/Edit Action Window NOTE If no Actions button appears in the Create/Edit Events window, the selected MultiSwitch 700 module does not support the Actions MIB. For more information about devices which support this MIB, contact the Global Call Center. 2.
Alarm Configuration a. If you know the exact name of the OID value you wish to track (including its capitalization), simply enter the name in the Variable field; to verify that you have entered the name correctly, click on the Find-> button to move the MIB Tree display to that OID. (If MIB Tree display does not adjust to show the OID you’ve entered, you’ve entered the name incorrectly; remember, case does count!) b.
Alarm Configuration Deleting an Alarm, Event, or Action To delete an alarm, event, or action: 1. In the appropriate window, highlight the alarm, event, or action you wish to remove. 2. Click on the Delete button to remove. A window will appear asking you to confirm your selection; click on the OK button to delete, or on the Cancel button to cancel.
Alarm Configuration The top portion of the window contains the device information boxes, as well as the event index number and the event description; the log itself includes the following fields: Index This uniquely identifies this occurrence of the event. Time Indicates the date and time of each event occurrence.
Alarm Configuration 4-28 How Rising and Falling Thresholds Work
Chapter 5 FDDI Management Concentrator configuration; connection policy; station list; concentrator performance; FDDI statistics; frame translation The FDDI menu lets you access windows to view a MultiSwitch 700 module’s FDDI configuration, connection policy, station list, and performance with respect to each Station Management (SMT) entity present on an installed DELHF-UA modular interface. You can also configure your module’s frame translation settings using the Frame Translation window.
FDDI Management • Connection Policy — This window shows the types of connections between the four FDDI PHY (port) types — A, B, M, and S — that will be allowed by the SMT entity. • Station List — With this window you can see the configuration of the ring on which the SMT entity resides, including number of nodes, node addresses (both Canonical and MAC), node class, and current ring topology.
FDDI Management Configuration The Concentrator Configuration window, Figure 5-2, informs you about the configuration and operating state of the FDDI ring associated with the selected SMT entity, and displays parameters relating to ring initialization. Figure 5-2. The Concentrator Configuration Window MAC State This field indicates the current state of the selecting ring’s MAC component. (The RMT component of SMT monitors MAC operation and takes actions necessary to aid in achieving an operational ring.
FDDI Management will not occur unless you are using locally-administered addresses, as factory-set MAC addresses are guaranteed to be unique. Ring-Op-Dup The ring is operational; however, the address of the MAC under control of the SMT entity has been found to duplicate that of another MAC on the ring. Corrective actions will be attempted before the duplicate address condition causes ring initialization to fail after the claim and beacon recovery process.
FDDI Management either continues its own bid (and removes the competing Claim Frame from the ring) or defers (halts transmission of its own bid and repeats the competing bid) according to the following hierarchy of arbitration: • A Claim Frame with the lowest TTRT bid has precedence. • If the values of TTRT are equal, the frame with the longest source address (48 vs. 16 bits) has precedence. • If both TTRT value and source address length are equal, the frame with the highest address has precedence.
FDDI Management • Secondary indicates that the MAC is inserted into the secondary path of the currently used FNB ring. • Local means that the MAC is not inserted into a primary or secondary path of a dual ring, but may be connected to one or more other nodes. This is not a valid value for the DELHF-UA. • Isolated means that the MAC has no connection to the ring or other concentrator ports. • Not Available means that there is no MAC on the FDDI ring associated with the selected SMT entity.
FDDI Management The following table summarizes the FDDI connection rules: Table 5-1. FDDI Connection Rules V X U P ! A B S M A V, U V V, U V, P B V V, U V, U V, P S V, U V, U V V M V V V X —valid connection —illegal connection —undesirable (but legal) connection; this requires that SMT is notified. —valid, but when both A and B are connected to M ports (a dual-homing configuration), only the B connection is used.
FDDI Management TIP You can use any SNMP Set Request or MIB tool to edit the Connection Policy for your device by setting the fddimibSMTConnectionPolicy MIB OID (part of the MIBII FDDI Transmission MIB (RFC1512). fddimibSMTConnectionPolicy is simply a 16-bit integer value (ranging from 32768 to 65535) that corresponds to the connection policy (in the “Reject X-Y” format, where X represents a port on the FDDI Switch Module, and Y represents the attaching node).
FDDI Management Station List The Station List illustrates the configuration of the ring associated with the currently selected SMT entity, including number of nodes on the ring, node addresses (both Canonical and MAC), node class, and ring topology. Figure 5-4.
FDDI Management Stations Panel The Stations Panel displays a list of the stations on the ring to which the selected SMT is connected, in ring sequence from the MAC, along with each station’s node class and current topology.
FDDI Management Performance The Concentrator Performance window, Figure 5-5, provides graphical and numeric performance statistics for the selected SMT entity, including transmit frames, receive frames, frame errors, lost frames, and ring ops. Figure 5-5. The Concentrator Performance Window Statistics are displayed in three ways: • By count (i.e., the number detected of each for the selected interval). • By rate (i.e., the number of each per second, as averaged over the selected interval).
FDDI Management Available statistics are: Transmit Frames The number of frames transmitted by the MAC associated with the SMT during the chosen interval. Receive Frames The number of frames received by the MAC associated with the SMT during the chosen interval. Frame Errors The number of error frames detected by the MAC associated with the SMT during the chosen interval that had not been detected previously by other stations.
FDDI Management Figure 5-6. The FDDI Statistics Window The FDDI Statistics window displays the following information for the module: SMT# This field displays the index number of Station Management (SMT) entity for the DELHF-UA. Frames/sec The number of frames/second (averaged over the specified poll interval) transmitted by the indicated SMT. KBytes/sec The number of kilobytes/second (averaged over the specified poll interval) transmitted by the indicated SMT.
FDDI Management Setting the FDDI Statistics Poll Rate To set the FDDI Statistics poll rate: 1. Click on the clock symbol ( ) next to the Poll Rate (sec) text box. The New Timer Interval text box, Figure 5-7, will appear. Figure 5-7. New Timer Interval Text Box 2. Using the mouse, click to highlight the hour field in the New Timer Interval text box. 3. Using the arrow keys to the right of the text box, scroll to change the hour, as desired. Notice that the time is given in a 24-hour hh:mm:ss format. 4.
FDDI Management Figure 5-8. The Frame Translation Window Information about Ethernet and FDDI Frame Types There are four frame types which can be transmitted on an IEEE 802.3/Ethernet network – Ethernet II, Ethernet 802.2, Ethernet 802.3 (or Raw Ethernet), and Ethernet SNAP; there two frame types which can be transmitted on an FDDI network: FDDI 802.2 and FDDI SNAP. Each of these frame types is described in more detail in the sections that follow. Bridges connecting IEEE 802.
FDDI Management If the frame is exiting the FDDI ring through another FDDI/Ethernet bridge, the FDDI frame must be converted back into an IEEE 802.3/Ethernet frame. As there are four potential Ethernet frame types to which the two FDDI frame types can be translated, you must determine which translation options you want in effect — depending on which network protocols and applications are being run on the destination network.
FDDI Management This is the default frame type for Novell NetWare software version 3.12 and beyond; it is also used for OSI packets on IEEE 802.x LAN networks. Ethernet 802.3 (Ethernet Raw) The Ethernet 802.3 frame format has an 802.3 MAC layer header (as do Ethernet 802.2 frames); however, it does not contain an 802.2 LLC header. Instead, Novell IPX is fixed within the packet as the network layer protocol. This frame type – also known as Raw 802.
FDDI Management FDDI SNAP The FDDI SNAP frame type has an FDDI header with a Frame Control field that provides FDDI framing information, and the 802.2 LLC header with FDDI Frame Control, a SNAP LSAP identifier, and a five byte protocol identifier. There is no FDDI equivalent for Ethernet 802.3 Raw frames or Ethernet II frames.
FDDI Management Translate all Ethernet Raw frames to This selection box lets you set the translation parameters for Ethernet Raw (Ethernet 802.3) packets. Ethernet Raw frames are used on networks running the IPX protocol on Novell NetWare versions prior to 3.12. Possible options are FDDI 802.

Current versions of DELHA-UA firmware use 802.
ATM Configuration Figure 6-1. The Current ATM Connections Window The Current ATM Connections window provides the following information about the device’s ATM connections: Connection Data The Connection Data fields provide the following information about each ATM interface available on the device: 6-2 I/F Displays the index number assigned to each DELHA-UA interface installed in a MultiSwitch 700 module. Maximum Allowed Displays the maximum number of connections allowed by current device firmware.
ATM Configuration Settings The Settings portion of the window contains a list box which displays information about each of the currently configured PVCs, as well as the fields used to configure new connections: I/F The device interface on which the PVC was configured. VPI Displays the Virtual Path Identifier assigned to the connection; current versions of DELHA-UA firmware allow values from 0-3.
ATM Configuration Refresh Selecting the Refresh button refreshes the connection information displayed in the window. Configuring Connections You can add a new connection or delete an existing connection as described in the following sections.

Chapter 7 WAN Configuration The DELHW-UA and its port interface modules; WAN redundancy; the WAN Logical View; changing WAN Logical settings The DELHW-UA Wide Area Networking (WAN) modular interface available for the DLE32-MA, DLE33-MA, and other MultiSwitch 700 modules provides LANto-WAN switching for the MultiSwitch 700 chassis. It supports IP and IPX bridging or routing services — including IP RIP — and multiple WAN connectivity options via two port interface module slots.
WAN Configuration Port interface modules available for the DELHW-UA include: DELDS-UI DDS is Digital Data Services, a digital network that supports data rates of 56Kbps or 64Kbps. The DDS service provides users with dedicated, two-way simultaneous transmission capabilities operating at transfer rates up to 64 Kbps. This port module comes with a built-in CSU/DSU.
WAN Configuration throughput of up to 1.544 Mbps. Time Division Multiplexing (TDM) allows for channelization of up to 24 links over a single physical T1/FT1 interface. DELTD-UI This port interface module provides both a T1 and DDS interface that allows you to easily switch between the two interfaces by changing the physical cabling and reconfiguring the desired interface with either QuickSET for the DELHW-UA or NetSight Element Manager.
WAN Configuration The WAN Logical View The WAN Logical View window displays information about the interfaces that are part of your physical port. The windows are identical for T1 and Synchronous ports. The number of entries is dependent on the type of port. The T1 port, for example, will have 24 entries. To access the WAN Logical View window from the DELHW-UA Chassis View: 1. Click on Device on the Chassis View menu bar; the device menu will appear. 2. Click on WAN Status and then select Logical View.
WAN Configuration Protocol Displays the active Link Layer protocol. This field displays PPP (Point to Point), Frame Relay, or Other. Compression Indicates whether data compression is activated or de-activated. NOTE Data compression is not supported by the DELHW-UA at this time; therefore, compression will always be de-activated or “Off”. MTU Displays the MTU (Maximum Transfer Unit) for this interface.
