The SmartSwitch 2000 Chassis View SmartSwitch 2000 Þrmware version 4.00.08 supports the pre-standard IEEE 802.1Q draft speciÞcation for port-based VLANs. NOTE For SmartSwitch 2000 Þrmware versions 4.00.08 and above, HSIM-F6 modules cannot be installed in a SmartSwitch 2000 that is operating in 802.1Q mode. What is a VLAN? A Virtual Local Area Network (VLAN) is a logical group of devices that function as a single Local Area Network segment (broadcast domain).
The SmartSwitch 2000 Chassis View 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 802.1Q switch, any frames received from that port will be classiÞed as belonging to the Default VLAN. When 802.1Q is implemented for a SmartSwitch 2000 that has an HSIM-A6DP installed, each LEC will be represented as an individual port which can be easily assigned membership in a VLAN.
The SmartSwitch 2000 Chassis View portÕs egress list). Dynamically learned VLANs are subject to the same aging rules as source addresses (e.g., if a tagged frame belonging to a dynamically learned VLAN is not received by the port within the switchÕs aging time, the transmitting stationÕs source address and VLAN will be aged out for that port; no unknown destination frames belonging to the stationÕs VLAN will be transmitted through the port until the VLAN is dynamically learned once again).
The SmartSwitch 2000 Chassis View Configuring Your 802.1Q VLANS Before you can deÞne and conÞgure 802.1Q port-based VLANs on your device, you must activate the deviceÕs 802.1Q operational mode; this operation can be performed using Local Management or the MIB Tools application. Using MIB Tools, 802.1Q mode can be activated through the Container MIBÕs Logical Entry Table (contLogicalEntryTable). When the 802.1Q component is activated, the device will automatically reset, and begin operating in 802.1Q mode.
The SmartSwitch 2000 Chassis View Figure 2-24. The VLAN ConÞg Window The ConÞgured VLANS list box and Þelds allow you to view, create, modify, delete, enable, and disable 802.1Q port-based VLANs. The list box displays the following information about your deÞned 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 SmartSwitch 2000 Chassis View Creating and Modifying VLANs The Þelds immediately below the ConÞgured 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 SmartSwitch 2000 Chassis View Enabling and Disabling VLANs NOTE Unless Enable is selected when a VLAN is initially deÞned, 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 VLANÕs port assignment, the VLAN should be disabled before changing the port conÞguration.
The SmartSwitch 2000 Chassis View Figure 2-25. The VLAN Port ConÞg 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 Þelds display the slot and port index for each port on your 802.1Q switch. For the SmartSwitch 2000, the slot index will always be 1. VLAN ID This Þeld displays the VLAN ID of the VLAN to which the port is currently assigned. Mode This Þeld displays the portÕs current mode of operation.
The SmartSwitch 2000 Chassis 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 Þeld displays the portÕs current frame discard format (discardTagged, discardUntagged, or noDiscard).
The SmartSwitch 2000 Chassis 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 SmartSwitch 2000 Chassis View Figure 2-26. The VLAN Egress Port ConÞg Window The list box at the top of this window is used to select a conÞgured VLAN for association with your switchÕs 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 Þeld displays the slot index for the device being conÞgured. VID This Þeld lists the VLAN IDs of the currently conÞgured VLANs on your switch.
The SmartSwitch 2000 Chassis View Under the list box there are two groups of check boxes that display the ports on the switch. A checkmark in the portÕs check box indicates that the VLAN selected in the list box is in the portÕs 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.
The SmartSwitch 2000 Chassis View 2. Select Broadcast Suppression. The Broadcast Statistics and Suppression window, Figure 2-27, will appear. Figure 2-27. The Broadcast Statistics and Suppression Window Port # This read-only Þeld indicates the number assigned to each interface on the device. Total RX Displays the total number of broadcast frames received on the interface since the device was last initialized.
The SmartSwitch 2000 Chassis View TIP In order to calculate the time since peak, subtract the value in the Time Since Peak column from the current sysUpTime displayed as Up Time in the front panel. Please note that the peak time you calculate will be within 5 minutes of the actual time since peak, as sysUpTime is polled by default at 3 minute intervals and the broadcast suppression values are polled by default at 2 minute intervals. To reset the Peak Rate and Time Since Peak values: 1.

Click on the OK button to save your changes, or on the Cancel button to cancel. NOTE In accordance with Year 2000 compliance requirements, SPECTRUM Element Manager now displays and allows you to set all dates with four-digit year values.
Chapter 3 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 SmartSwitch 2000, you can conÞgure alarms and events (and, where appropriate, actions) for each available interface. TIP The Alarm, Event, and Actions windows described in this chapter are identical to those provided via the RMON utility.
Alarm Configuration Using the Advanced Alarms feature, you can deÞne custom alarms for almost any MIB-II or RMON object, as long as it is present in the device Þrmware and its value is deÞned as an integer (including counters, timeticks, and gauges).
Alarm Configuration TIP If you are familiar with the RMON MIB and/or with the original Alarm and Event functionality provided by SPECTRUM Element Manager (now known as the Advanced Alarm functionality), you will note that the Basic Alarm ConÞguration window combines the three parts of creating a working alarm Ñ conÞguring the alarm itself, conÞguring an event that will announce the occurrence of an alarm (including assigning any actions), and linking the two Ñ into a single step, and handles the details t
Alarm Configuration TIP You can also access the Alarms function Ñ and the rest of the RMON functionality Ñ by selecting the RMON option from the Chassis View Utilities menu. When the window is Þrst launched, no interfaces will be selected, and the Apply, Disable, and View Log buttons will be grayed out: the Apply and Disable buttons will activate when an interface is selected; the View Log button will activate when an interface which has experienced an alarm event is selected.
Alarm Configuration IF Number Displays the interface number assigned to each available interface. IF Type Displays each interfaceÕs 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.
Alarm Configuration Falling Action Indicates whether or not a falling alarm occurrence will initiate any actions in response to the alarm condition: Enable if bridging will be enabled at the selected interface in response to a falling alarm, Disable if bridging will be disabled in response to a falling alarm, and None if no actions have been conÞgured for the selected alarm. Note that the Action Þelds will be unavailable for devices conÞgured to operate in SecureFast switching mode.
Alarm Configuration 3. In the Interval field, enter the amount of time, in days, hours, minutes, and 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 time interval up to 24,855 days. If you set an incorrect time value (e.g., you enter 75 minutes instead of 1 hour, 15 minutes) you will receive an error message. Click OK and enter the correct time value. 4.
Alarm Configuration 6. Click in the Rising Threshold field; enter the high threshold value for this alarm. Remember, compared values are always relative, or delta values (the difference between the value counted at the end of the current interval and the value counted at the end of the previous interval); be sure to set your thresholds accordingly.
Alarm Configuration To conÞgure additional alarms, or alarms of a different type, select the appropriate alarm variable at the top of the window, highlight the appropriate interface(s), and repeat the procedures outlined above. 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.
Alarm Configuration Figure 3-2.
Alarm Configuration Description Provides a detailed description of the condition which triggered the alarm, including whether it was a Rising or Falling alarm, the Value which triggered the alarm, and the conÞgured Threshold that was crossed. Each log will hold only a Þnite number of entries, which is determined by the resources available on the device; when the log is full, the oldest entries will be replaced by new ones.
Alarm Configuration Figure 3-3. The RMON Advanced Alarm/Event List Window NOTES Neither the Alarms or Events list is interface-speciÞc; both will be displayed the same for every interface. Note, too, that alarms and events which have been conÞgured 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 Þelds in the Alarms Watch display include: Index The index is a number that uniquely identiÞes each alarm. Index numbers are user-deÞned; 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. Note that indices 2000 to 3999 are reserved and unavailable.
Alarm Configuration Note that 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 Þelds in the Events Watch display include: Index This is a number that uniquely identiÞes an entry in the event table; an index number is assigned when an event is created.
Alarm Configuration these parameters are editable: to change an existing alarm, edit any parameter except the Index value; to create an entirely new alarm, simply assign a new Index number. The ability to assign index numbers allows you to quickly and easily create a number of similar alarms without having to close, then re-open the window or re-assign every parameter.
Alarm Configuration Figure 3-4. 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 SmartSwitch 2000, some owner identification can prevent alarms from being altered or deleted accidentally.
Alarm Configuration NOTE Clicking on the Index button to select the next available index number will replace the current Owner string with the default value described above; if the default value is already in place, the date and time will be updated. If you wish to modify an existing alarm, enter the appropriate index value, or double-click on the alarm of interest in the Alarms Watch list (in the main Alarm/Event window).
Alarm Configuration NOTE If you select an object which is not resident in the device Þrmware, you will receive a ÒSet Failed; ensure variable is readableÓ message when you try to set your alarm by clicking on the Apply button.
Alarm Configuration NOTE If you wish to set an alarm on an object whose instance is non-integral Ñ for example, a Host Table object indexed by MAC address Ñ 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 deÞning the instance. For these OIDs, the instance deÞnition 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 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 modiÞed. Figure 3-5. The RMON Create/Edit Events Window 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 window and help you distinguish among the events you have configured. 4. Any value you enter in the Community field will be included in any trap messages issued by your SmartSwitch 2000 when this event is triggered; this value is also used to direct traps related to this event to the appropriate management workstation(s): a.
Alarm Configuration NOTES In order for the trap selection to work properly, your SmartSwitch 2000 must be conÞgured to send traps to the management station. This is accomplished via local management; consult your device hardware manual for more information. If you are monitoring a variable you consider to be critical, we do not recommend that you select Trap as the only event response; if a trap is lost due to a collision or other transmission problem, it will not be re-sent. c.
Alarm Configuration NOTE If no Actions button appears in the Create/Edit Events window, the selected RMON device does not support the Actions MIB. The Actions functionality will only be available for Cabletron devices, as it is supplied by a Cabletron proprietary MIB; for more information about devices which support this MIB, contact Cabletron Systems Technical Support. Figure 3-6. The RMON Create/Edit Actions Window 2.
Alarm Configuration TIP If you select an invalid OID Ñ that is, one which does not permit write access Ñ the message !!CanÕt set action on this type!! will be displayed in the Variable Þeld. If you donÕt know the exact spelling of the OID you wish to use for your alarm variable, and you canÕt Þnd it by searching through the tree, use the MIB Tool Find feature to locate the OID and determine its exact spelling (and tree location).
Alarm Configuration Viewing an Advanced Alarm Event Log To view the log of occurrences for any event: 1. Highlight the event for which you wish to view the log, then click on the Event Log button at the bottom of the Advanced Alarm/Event List window; the Event Log window, Figure 3-7, will appear. Figure 3-7.
Alarm Configuration triggered the alarm, the conÞgured threshold that was crossed, and the event description. Use the scroll bar at the bottom of the log to view all the information provided. Each log will hold only a Þnite number of entries, which is determined by the resources available on the device; when the log is full, the oldest entries will be replaced by new ones.
Chapter 4 Statistics Accessing interface statistics from the Chassis View; available statistics windows Each port menu in the SmartSwitch 2000 Chassis View provides two statistics selections: Statistics and I/F Statistics.
Statistics or For MIB-II interface statistics, click to select I/F Statistics. The MIB-II Interface Statistics window (Figure 4-3) will appear. 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 UserÕs Guide for information on how to check (and if necessary, change) the admin status of the RMON Default MIB component.
Statistics 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 4-5, for more information. Ethernet statistics are: Bytes Displays the total number of bytes contained in packets processed on the network segment. This number includes bytes contained in error packets. Packets Displays the total number of packets processed on the network segment.
Statistics 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). Jabbers Indicates the number of packets processed by the network segment that were oversized (greater than 1518 bytes; a giant packet) and had either a non-integral number of bytes (alignment error) or a bad frame check sequence (CRC error).
Statistics The percentages displayed to the right of the numerical values for these Þelds indicate what percentage of all packets transmitted on the network segment were of the noted size. Unless the network segment has experienced a signiÞcant number of runts and/or giants (which are not counted in this group), these percentages will add up to 100.
Statistics To temporarily freeze the statistics display, select the Freeze Stats option; in this mode, statistics will continue to be collected, but the display will not update. To resume normal updates, click again to de-select the freeze option. Printing Statistics The Print button located at the bottom of the Statistics window allows you to print the current snapshot of statistical data. When you select Print, a standard Windows print window like the sample shown in Figure 4-2 will appear. Figure 4-2.
Statistics TIP Remember, this window can always be launched from the I/F Statistics option on the Chassis View port menus; it may also be launched from the Statistics option if the selected interface does not support RMON or if the RMON Default MIB component has been administratively disabled.
Statistics The lower portion of the window provides the following transmit and receive statistics; note that the Þrst 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.
Chapter 5 Managing Ethernet MicroLAN Switches Viewing the Statistics, Timer Statistics, and Performance Graph windows; using the repeater, board, and port Alarm Limits windows; setting alarm limits; link state traps, segmentation traps, and source address traps The Repeater menu lets you access windows to monitor and manage repeated Ethernet networks supported by a SmartSwitch 2000 Ethernet MicroLAN Switch (e.g., the 2E43-51 or 2E43-51R).
Managing Ethernet MicroLAN Switches TIP Although you can launch most statistics windows from both the Repeater and Module menus, the information provided at both levels will be the same, since each ÒboardÓ on the Ethernet MicroLAN Switch is equivalent to a repeater channel. The Statistics Windows At the Statistics windows, you can view accumulated statistics and error breakdowns for each network supported by the Ethernet MicroLAN Switch, and for each individual module and port.

For an individual port, the number of Active Users can tell you whether the port is supporting a station or trunk connection.
Managing Ethernet MicroLAN Switches Soft Errors CRC Errors NOTE Displays the total number of packets with CRC (Cyclical Redundancy Check) errors that the repeater, board, or port has received from the network. CRC errors occur when packets are somehow damaged in transit. Alignment Errors Displays the total number of misaligned packets received by the repeater, board, or port. A misaligned packet is one that contains a non-integral number of bytes (that is, any unit of bits less than a byte).
Managing Ethernet MicroLAN Switches Timer Statistics You can use the Timer Statistics windows to gather statistical information concerning the repeater channels on your Ethernet MicroLAN Module and its boards and/or ports over a user-set time period. Statistics are displayed both numerically and graphically, using color-coded, dynamic bar charts. These bar charts display the elapsed, average, and peak values for percent load, percent collisions, and percent errors at the repeater, board, or port level.

Chapter 6 FDDI Applications Concentrator configuration; connection policy; station list; concentrator performance; FDDI statistics; frame translation The FDDI menu lets you access windows to view a SmartSwitch 6000Õs FDDI conÞguration, connection policy, station list, and performance with respect to each Station Management (SMT) entity present on an installed HSIM-F6 High Speed Interface Module. You can also conÞgure your moduleÕs frame translation settings using the Frame Translation window.
FDDI Applications ¥ Station List Ñ With this window you can see the conÞguration 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 ¥ Performance Ñ This window lets you view the number of frames transmitted and received on the ring as detected by the selected SMT entity, along with error and lost frames, and the number of ring initializations.
FDDI Applications Figure 6-2. The Concentrator ConÞguration Window MAC State This Þeld indicates the current state of the MAC on the FDDI ring associated with the selected SMT entity. The RMT component of SMT monitors MAC operation and takes actions necessary to aid in achieving an operational ring.
FDDI Applications Non-Op-Dup The ring is not operational; the address of the MAC under control of the SMT entity has been found to duplicate that of another MAC on the ring. The duplicate address condition prevented ring recovery and initialization after a claim and beacon process. This state will not occur unless you are using locally- administered addresses, as factory-set MAC addresses are guaranteed to be unique.
FDDI Applications T-Req. (Requested Target Token Rotation Time) The token rotation time bid made by the selected SMT entity during ring initialization. Each station detecting that the ring must be initialized begins a claim token process and issues a stream of Claim Frames, which negotiate the value assigned to the Target Token Rotation Time (TTRT). The information Þeld of these frames contains the issuing stationÕs bid for the value of TTRT.
FDDI Applications ¥ Secondary 2 indicates that the Secondary 2 FDDI ring is being used. ¥ Local means that the MAC is connected to one or more nodes but is not connected to the dual ring. ¥ Isolated means that the MAC has no connection to the ring or other concentrator ports. ¥ Unknown or ? indicates that your Cabletron management application cannot determine the MAC path for the HSIM-F6. Ring Configuration The current conÞguration of the MAC and physical layers of the A and B ports.
FDDI Applications The following table summarizes the FDDI connection rules: Table 6-1. FDDI Connection Rules 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 V — valid connection X — illegal connection U — undesirable (but legal) connection P — valid, but when both A and B are connected to M ports (a dual-homing configuration), only the B connection is used.
FDDI Applications 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 ÒReject X-YÓ format, where X represents a port on the FDDI Switch Module, and Y represents the attaching node).
FDDI Applications Figure 6-4. The Station List Window Address Mode Displays the current mode being used to display the addresses of the devices in the Station List. The two possible modes are Canonical (FDDI) or MAC (Ethernet). To change the current Address Mode, click on the Address Mode button at the bottom of the window. The current address mode will change in the Address Mode Þeld and the Stations panel.
FDDI Applications MAC Address Displays the manufacturer-set MAC address of the node inserted into the ring. MAC addresses are hard-coded into the device and are not conÞgurable. Node Class Displays the type of ring device. Possible values are: Station Indicates an FDDI node capable of transmitting, receiving, and repeating data. Concentrator Indicates an FDDI node that provides attachment points to the ring for stations that are not directly connected to the dual ring.
FDDI Applications 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). ¥ Graphically, as a percentage of each with respect to total network load processed by the HSIM-F6 during the last interval. You can view the concentrator performance for three different intervals: ¥ Absolute Ð Counts recorded since the device was last started.
FDDI Applications Ring Ops The number of times the ring has entered the ÒRing OperationalÓ state from the ÒRing Not OperationalÓ state during the selected interval. This counter updates when the HSIM-F6Õs MAC informs Station Management (SMT) of a change in Ring Operation status.
FDDI Applications KBytes/sec The number of kilobytes/second (averaged over the speciÞed poll interval) transmitted by the indicated SMT. Peak KBytes/sec The peak number of kilobytes/second transmitted by the indicated SMT, as detected over all polling intervals since monitoring began (i.e., since the FDDI Statistics window was Þrst opened).
FDDI Applications Configuring FDDI Frame Translation Settings The HSIM-F6 interface must be conÞgured to translate packets from an FDDI frame format to an Ethernet frame format (and vice versa) when bridging packets between FDDI and Ethernet networks. The Frame Translation window lets you set the parameters for frame translation. To access the FDDI Translation window (Figure 6-8): 1. In the Chassis View window, click on FDDI to display the FDDI menu. 2. Click on Frame Translation. Figure 6-8.
FDDI Applications In most instances, the IEEE 802.3/Ethernet frame format is translated automatically into the appropriately corresponding FDDI frame format. Ethernet 802.2 frames are translated to FDDI 802.2 frames; Ethernet II frames are translated to FDDI SNAP frames; non-AppleTalk Ethernet SNAP frames are translated to FDDI SNAP frames; and AppleTalk Ethernet SNAP frames are translated to FDDI SNAP frames (AppleTalk format).
FDDI Applications Ethernet 802.2 The Ethernet 802.2 frame format is the IEEE 802.3 formalization of the original Ethernet frame format. This frame format is similar to the Ethernet II frame format, except that the two byte Type Þeld is eliminated and replaced with a two byte Length Þeld, and an 802.2 LLC header is encapsulated within the 802.3 frame.
FDDI Applications FDDI Frames There are two legal FDDI data frame types: FDDI 802.2 The FDDI 802.2 frame type has two headers: the FDDI header (which includes the Frame Control Þeld that indicates the class of frame, length of the address Þeld, and the type of FDDI frame), and the 802.2 header. FDDI SNAP The FDDI SNAP frame type has an FDDI header with a Frame Control Þeld that provides FDDI framing information, and the 802.
FDDI Applications OUI of 00-00-00 (indicating TCP/IP) and an IP protocol type identiÞer (08-00). Possible options are Enabled (allow IP fragmentation Ð the default) or Disabled (prevent IP fragmentation, and discard frames over 1518 bytes). Translate all Non-Novell FDDI SNAP frames to This selection box lets you set the translation parameters for non-Novell FDDI SNAP frames.
Chapter 7 ATM Configuration Viewing connection data; configuring Permanent Virtual Circuits (PVCs); adding and deleting connection entries The ATM Connections option will be available when you have an HSIM-A6DP installed and enabled in your SmartSwitch 2000. The ATM interfaces provided by an ATM HSIM-A6DP provide the connectivity that allows you to merge ATM network segments with traditional LAN technologies.
ATM Configuration Figure 7-1. Current ATM Connections Window The Current ATM Connections window provides the following information about the deviceÕs ATM connections: Connection Data The Connection Data Þelds provide the following information about each ATM interface available on the device: I/F Displays the index number assigned to each ATM interface present on the selected module. The HSIM-A6DP will provide a single ATM interface, indexed 27.
ATM Configuration VPI Displays the Virtual Path IdentiÞer assigned to the connection. Virtual Path IdentiÞers are used to group virtual connections, allowing for channel trunking between ATM switches. Each VPI can be conÞgured to carry many different channels (designated by VCIs) between two points. VCI Displays the Virtual Channel IdentiÞer assigned to the connection; allowable values are 0 - 1023 for each VPI.
ATM Configuration Configuring Connections Adding a New Connection To conÞgure new Permanent Virtual Circuits (PVCs), enter the following information in the text Þelds which appear just below the settings list box: 1. In the I/F text box, click on the down-arrow to the right of the text field, and select the interface for which you wish to configure a connection. All available ATM interfaces will be listed in this menu. 2.
Chapter 8 HSIM-W87 Configuration Configuring the T3 interface; configuring T1 connections; setting priority IP Addresses The HSIM-W87 is a High Speed Interface Module that provides Wide Area Network (WAN) services. The HSIM has a DS3 interface (T3), providing up to 28 separate DS1 connections (T1). The HSIM-W87 design provides WAN connectivity to any SmartSwitch that supports HSIM connections. The HSIM-W87 operates in a switching/bridging mode.
HSIM-W87 Configuration Click here to select or deselect an option button. Figure 8-1. The T3 ConÞg Window The T3 ConÞg window provides the following information about the deviceÕs T3 conÞguration and allows you to set certain values: Time Elapsed Indicates the number of seconds that have elapsed since the beginning of the near end current error-measurement period. To update this Þeld you must close and reopen the window.
HSIM-W87 Configuration Line Status This Þeld indicates the line status of the interface. It contains loopback state and failure state information. Scroll to view all of the status information, if necessary. T3 Line Type Select the type of DS3 or C-bit application implementing this interface: M23 or CbitParity. The type of interface affects the interpretation of the usage and error statistics. T3 Loop Back Select the loopback conÞguration of the T3 interface. Options are: No Loop Not in a loopback state.
HSIM-W87 Configuration Click here to select or deselect an option. Figure 8-2. The T1 ConÞg Window At the top of the T1 ConÞg window a list box displays conÞguration information for each T1 connection (line). When you highlight a speciÞc T1 line by clicking on it, the Þelds below the list box display the current values for that line, and allow you to change those values.
HSIM-W87 Configuration Valid Intervals Displays the number of previous intervals for which valid data was collected. The value will be 96 unless the interface was brought online within the last 24 hours, in which case the value will be the number of complete 15-minute intervals since the interface has been online. T1 Frame Type Displays the type of service you are using over your T1 line.
HSIM-W87 Configuration Configuring IP Priority The IP Priority ConÞguration window allows you to assign priority transmission to up to 16 IP addresses communicating across the HSIM-W87. To access the IP Priority ConÞg window: 1. Click on the appropriate Module Index to access the Module menu. 2. Select IP Priority Config. The IP Priority Config window, Figure 8-3, will appear. Figure 8-3.
