1. OVERVIEW Digital Networks WebView Description This user guide describes Digital Networks WebView, a Web browserbased utility which allows you to remotely configure and manage Digital Networks products, including the DNswitch 800. There is no software to install as Web management capability is built into the switch’s management. Digital Networks WebView provides a graphical, real-time representation of the front panel on the DNswitch 800.
Conventions This guide uses the following user input conventions: • When you read “Select,” use the mouse to either select the link identified by a hand icon, or select the identified button or area. • When you read “Enter,” type in the text and select the button identified in the procedure.
2. USING WEB-BASED MANAGEMENT Setting Up Web Management Before running Web-based management, some basic configuration of the switch may need to be performed. The following information at a minimum must be configured or known for the switch to be managed: • IP Address • Administrator password • HTTP Server Enable In addition, several other parameters may need to be configured or known to properly communicate with the switch or allow full management capability.
Setting a Default Gateway The default gateway parameter defines the IP address of a router or other network device to which IP packets are to be sent if destined for a subnet outside of that in which the switch is operating. This parameter must be set if you are attempting to manage the switch using Digital Networks WebView from a remote network or across the Internet. 1. Starting at the Main Menu of the console user interface, select Management Setup Menu / Network Configuration / IP Configuration. 2.
Enabling Web Management The HTTP Configuration menu is used to enable or disable the ability to manage the switch with Web management. The HTTP Server parameter must be set to ENABLED before Digital Networks WebView can be used to manage the switch. If it is desired to disallow Web management of the switch, this parameter should be set to DISABLED 1. Starting at the Main Menu of the console user interface, select Management Setup Menu / Network Configuration / HTTP Configuration. 2.
Digital Networks WebView User Interface The Digital Networks WebView user interface provides access to various switch configuration and management screens, allows you to view performance statistics, and permits you to graphically monitor system status. Areas of the User Interface Figure 2-1 shows the Digital Networks WebView user interface. The user interface is divided into four distinct areas as described in Table 2-1. Area 1 Area 3 Area 2 Figure 2-1.
Table 2-1. Areas of the User Interface Area Function 1 Presents a graphical near real-time image of the front panel of the selected switch. This area displays the switch’s ports, showing port activity, duplex mode, or flow control, depending on the specified mode. Various areas of the graphic can be selected for performing management functions, including the ports, management, or the case. 2 Displays a list of links allowing you to go to the associated menu or screen by selecting the item.
Configuration Options Web pages that include selection options have a drop-down list with a “Select” button to confirm the selection. Configurable parameters have a dialog box or a drop-down list. Once a configuration change has been made on a page, be sure to click on the “Apply” button at the bottom of the page to confirm the new setting. The following table summarizes the Web page configuration buttons. Table 2-3.
3. CONFIGURING AND MONITORING THE SWITCH This section, arranged by topic, describes how to perform common monitoring and configuration tasks on a DNswitch 800 using Digital Networks WebView. After you have properly configured the switch, and started Digital Networks WebView, you can perform any of the tasks described in the following sections. Screen Hierarchy The contents of this chapter are arranged following the structure shown in Figure 3-1. Figure 3-1.
System Information Use the System Information screen to display descriptive information about the switch, or for quick system identification as shown in the following figure and table. Figure 3-2. System Information Parameter System Name Description 1 Name assigned to the switch system. Object ID MIB II object identifier for switch’s network management subsystem. IP Address2 IP address of the switch you are managing. The switch’s management supports SNMP over UDP/IP transport protocol.
Switch Information Use the Switch Information screen to display hardware/firmware version numbers for the switch, as well as the power status of the system. Main Board Figure 3-3. Switch Information - Main Board Parameter Description Serial Number Serial number of the main board. Number of Ports Number of ports on the switch. Hardware Version Hardware version of the main board. Firmware Version System firmware version in ROM. POST ROM Version Management’s Power-on Self-test version.
IP Configuration Use the IP Configuration screen to set the bootup option, configure the Ethernet IP address for the switch, or set the number or concurrent Telnet sessions allowed. The screen shown below is described in the following table. Figure 3-4. IP Configuration Parameter Default Description IP State BootP-Get-IP Specifies whether IP functionality is enabled via manual configuration, or set by Boot Protocol (BootP).
SNMP Configuration Use the SNMP Configuration screen to display and modify parameters for the Simple Network Management Protocol (SNMP). The switch includes an SNMP agent which monitors the status of its hardware, as well as the traffic passing through its ports. A computer attached to the network, called a Network Management Station (NMS), can be used to access this information. Access rights to the switch are controlled by community strings.
Trap Managers The following figure and table describe how to specify management stations that will receive authentication failure messages or other trap messages from the switch. Up to 5 trap managers may be entered. Figure 3-6. Trap Managers Parameter Description Trap Manager Capability Up to 5 trap managers may be used. Trap Manager IP Address IP address of the trap manager. Trap Manager Community String A community authorized to receive trap messages.
Security Configuration Use the Security Configuration screen to restrict management access based on a specified password. The Administrator has write access for parameters governing the switch. You should therefore assign a password to the Administrator as soon as possible, and store it in a safe place. (If for some reason your password is lost, or you cannot gain access to the system’s configuration program, contact Digital Networks Technical Support for assistance.) Change Password Figure 3-7.
Firmware Upgrade Options You can upgrade system firmware via a Web browser, a TFTP server, or a direct connection to the console port (refer to the DNswitch 800 Management Guide). Web Upload Management Use the Web Upload Management menu to load software updates into the switch. The upload file should be a DNswitch 800 binary file from Digital Networks; otherwise the switch will not accept it. The success of the upload operation depends on the quality of the network connection.
TFTP Download Management Use the TFTP Download Management menu to load software updates into the switch. The download file should be a DNswitch 800 binary file from Digital Networks; otherwise the switch will not accept it. The success of the download operation depends on the accessibility of the TFTP server and the quality of the network connection. After downloading the new software, the switch will automatically restart itself.
Configuration Save and Restore Use the Configure screen to save the switch configuration settings to a file on a TFTP server. The file can be later downloaded to the switch to restore the switch’s settings. The success of the operation depends on the accessibility of the TFTP server and the quality of the network connection. Configuration Upload Management Use the Configuration Upload Management to save the switch configuration to a file on a TFTP sever.
Address Table Configuration The Address Table contains the unicast MAC addresses and VLAN identifier associated with each port (that is, the source port associated with the address and VLAN), sorted by MAC address or VLAN. You can also clear the entire address table, or information associated with a specific address; or set the aging time for deleting inactive entries. The information displayed in the Address Table is indicated in the following figure and table. Figure 3-12.
STA (Spanning Tree Algorithm) The Spanning Tree Algorithm can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the switch to interact with other bridging devices (that is, STAcompliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network. For a more detailed description of how to use this algorithm, refer to Appendix A, “Spanning Tree Concepts,” in the Management Guide.
Spanning Tree Information The Spanning Tree Information screen displays a summary of the STA information for the overall bridge or for a specific port. To make any changes to the parameters for the Spanning Tree, use the STA Configuration and STA Port Configuration screens. Spanning Tree The parameters shown in the following figure and table describe the current bridge STA Information. Figure 3-13.
Ports The parameters shown in the following figure and table are for port STA Information (Port 1-8). Figure 3-14. STA Information - Ports Parameter Description Port Status Displays the current state of this port within the spanning tree: No Link There is no valid link on the port. Disabled Port has been disabled by the user or has failed diagnostics. Blocked Port receives STA configuration messages, but does not forward packets.
Parameter Description Designated Bridge The priority and MAC address of the device through which this port must communicate to reach the root of the spanning tree. Designated Port The priority and number of the port on the designated bridging device through which this switch must communicate with the root of the spanning tree. Spanning Tree Configuration The following figures and tables describe Bridge STA configuration. Switch Figure 3-15.
When the Switch Becomes Root Figure 3-16. STA Configuration - When the Switch Becomes Root Parameter Default Description Hello Time 2 The time interval (in seconds) at which the root device transmits a configuration message. The minimum value is 1. The maximum value is the lower of 10 or [(Max. Message Age / 2) -1]. Max (Message) Age 20 The maximum time (in seconds) a device can wait without receiving a configuration message before attempting to reconfigure.
STA Port Configuration The following figure and table describe STA configuration for ports. Figure 3-17. STA Port Configuration Parameter Default Description Fast forwarding mode ENABLED Allows you to enable or disable fast forwarding for all ports on the switch. Priority Defines the priority for the use of a port in the STA algorithm. If the path cost for all ports on a switch are the same, the port with the highest priority (i.e.
Parameter Default Description FastForwarding ENABLED This parameter is used to enable/disabled the Fast Spanning Tree mode for the port. In this mode, ports skip the Blocked, Listening and Learning states and proceed straight to Forwarding. FastForwarding enables end-node workstations and servers to overcome time-out problems when the Spanning Tree Algorithm is implemented in a network. Therefore, FastForwarding should only be enabled for ports that are connected to an endnode device.
Bridge Settings Figure 3-19. Bridge Settings Parameter Description Traffic Class* Multiple traffic classes are supported by this switch as indicated under Bridge Capabilities. However, you can disable this function by clearing this checkbox. VLAN Learning As default this switch uses Shared VLAN Learning (SVL), whereby all ports share one VLAN filtering database. However, you can set the switch to use Independent VLAN Learning (IVL), where each port maintains its own filtering database.
Priority IEEE 802.1p defines up to 8 separate traffic classes. This switch supports Quality of Service (QoS) by using two priority queues, with weighted fair queuing for each port. You can use the Priority menu to configure the default priority for each port, or to display the mapping for the traffic classes as described in the following sections. Port Priority Configuration The default priority for all ingress ports is zero.
Port Traffic Class Information This switch provides two priority levels with weighted fair queuing for port egress. This means that any frames with a default or user priority from 03 are sent to the low priority queue “0” while those from 4-7 are sent to the high priority queue “1” as shown in the following screen: Figure 3-21. Port Traffic Class Information Parameter Description Port Numeric identifier for switch port.
VLAN Management Use the VLAN Management screen to define which VLAN has management access to the switch. Parameters shown on this screen are indicated in the following figure and table.: Figure 3-22. VLAN Management Parameter Default Description CPU Join VLAN All Select ALL to give all VLANs access to switch management, or ONE to restrict access to a specified VLAN. If you select just one VLAN, you must specify its VLAN ID on the following line.
Configuring Virtual LANs You can use the VLAN configuration menu to assign any port on the switch to any of up to 256 LAN groups. In conventional networks with routers, broadcast traffic is split up into separate domains. Switches do not inherently support broadcast domains. This can lead to broadcast storms in large networks that handle a lot of IPX and NetBeui traffic. By using IEEE 802.
VLAN Current Table This screen shows the current port members of each VLAN and whether or not the port supports VLAN tagging. Ports assigned to a large VLAN group that crosses several switches should use VLAN tagging. However, if you just want to create a small port-based VLAN for one or two switches, you can assign ports to the same untagged VLAN (page 36). The current configuration is shown in the following screen. Figure 3-24.
VLAN Static List Use this screen to create or remove VLAN groups. Figure 3-25. VLAN Static List Parameter Description Current Lists all the current VLAN groups created for this system. Up to 256 VLAN groups can be defined. To allow this switch to participate in external VLAN groups, you must use the VLAN ID for the concerned external groups. New Allows you to specify the name and numeric identifier for a new VLAN group.
Use the screens shown below to assign ports to the specified VLAN group as an IEEE 802.1Q tagged port. Assign ports as tagged if they are connected to 802.1Q VLAN compliant devices. If the port is connected to VLAN-unaware devices, frames will passed to the untagged VLAN group this port has been assigned to under VLAN Port Configuration (page 36). Figure 3-27. VLAN Static Table - Port Assignment Parameter Description Egress Ports Adds ports to the specified VLAN.
VLAN Static Membership by Port Use the screen shown below to assign VLAN groups to the selected port. To perform detailed port configuration for a specific VLAN, use the VLAN Static Table (page 33). Figure 3-28. VLAN Static Membership by Port Parameter Description Port Number Port number on the switch selected from the upper display panel. Add/Remove Add or remove selected VLAN groups for the port indicated in the Port Number field.
VLAN Port Configuration Use this screen to configure port-specific settings for IEEE 802.1Q VLAN features. Figure 3-29. VLAN Port Configuration Parameter Description PVID The VLAN ID assigned to untagged frames received on this port. Use the PVID to assign ports to the same untagged VLAN. Acceptable Frame Type1 This switch accepts “All” frame types, including VLAN tagged or VLAN untagged frames. Note that all VLAN untagged frames received on this port are assigned to the PVID for this port.
IGMP Multicast Filtering Multicasting is used to support real-time applications such as video conferencing or streaming audio. A multicast server does not have to establish a separate connection with each client. It merely broadcasts its service to the network, and any hosts which want to receive the multicast register with their local multicast switch/router.
Multicast Router Port Information You can use the Multicast Router Port Information screen to display the ports on this switch that are attached to a neighboring multicast router/ switch for each VLAN ID. Figure 3-31. Multicast Router Port Information Parameter Description VLAN ID The VLAN ID assigned to the multicast group in the displayed port list. Multicast Router Port List The list of switch ports that are attached to a neighboring multicast router/switch.
Static Multicast Router Port Configuration You can use the Static Multicast Router Port Configuration screen to assign ports that are attached to a neighboring multicast router/switch. Figure 3-32. Static Multicast Router Port Configuration Parameter Description Current A list of the switch ports that have been manually configured as being attached to a neighboring multicast router/switch. VLAN ID The VLAN ID assigned to the multicast group that is to be added/ removed from the list.
IGMP Member Port Table You can use the IGMP Member Port Table screen to assign ports that are attached to hosts who want to receive a specific multicast service. Figure 3-33. IGMP Member Port Table Parameter Description IGMP Member Port List The current switch ports that are listed as being attached to a IGMP host. VLAN ID The VLAN ID assigned to this multicast group. Multicast IP The IP address of a specific multicast service requested by the host.
IP Multicast Registration Table Use the IP Multicast Registration Table to display all the multicast groups active on this switch, including multicast IP addresses and the corresponding VLAN ID. Figure 3-34. IP Multicast Registration Table Parameter Description VLAN ID VLAN ID assigned to this multicast group. Multicast IP Address IP address for specific multicast services. Learned by Indicates the manner in which this address was learned: dynamic or IGMP.
Port Menus Port Information The Port Information screen displays the port status, link state, the communication speed and duplex mode, as well as the flow control and 802.1Q Trunk status. To change any of the port settings, use the Port Configuration menu. The parameters shown in the following figure and table are for the RJ-45 ports. Figure 3-35. Port Information Parameter Description Admin Status Shows if the port is enabled or not.
Port Configuration Use the Port Configuration menus to configure any port on the switch. Figure 3-36. Port Configuration Parameter Default Description Flow Control Mode Enabled Allows you to enable or disable flow control for all ports on the switch. Admin Status Enable Allows you to disable a port due to abnormal behavior (e.g., excessive collisions), and then reenable it after the problem has been resolved. You may also disable a port for security reasons.
Port Broadcast Storm Protect Configuration Use the Port Broadcast Storm Protect Configuration screen to configure broadcast storm control for any port on the switch. Figure 3-37. Port Broadcast Storm Protect Configuration Parameter Default Description Broadcast Storm Protect Mode Enabled Allows you to enable/disable broadcast storm control for all ports on the switch. Protect Status Enabled Enables/disables broadcast control for the port.
Port Security Configuration Use the Port Security Configuration screen to enable and configure port security for the switch. Port Security allows you to configure each port with a list of MAC addresses of devices that are authorized to access the network through that port. Figure 3-38. Port Security Configuration Parameter Description Port Number The port number on the unit. Status Port security can set to three states; Enabled, Disabled, or Learning.
Using a Port Mirror for Analysis You can mirror traffic from any source port to a target port for real-time analysis. You can then attach a logic analyzer or RMON probe to the target port and study the traffic crossing the source port in a completely unobtrusive manner. When mirroring port traffic, note that the target port must be configured in the same VLAN and be operating at the same duplex mode as the source port (see VLAN Static List on page 33).
Port Trunk Configuration Port trunks can be used to increase the bandwidth of a network connection or to ensure fault recovery. You can configure up four trunk connections (combining 2-4 ports into a fat pipe) between any two DNswitch 800 switches. However, before making any physical connections between devices, use the Trunk Configuration menu to specify the trunk on the devices at both ends. When using a port trunk, note that: • Ports can only be assigned to one trunk.
Use the Port Trunking Configuration screen to set up port trunks as shown below: Figure 3-40. Port Trunk Configuration Parameter Description Trunk Number A unique identifier for this trunk. You can configure up to four trunks per switch. Port The port members of this trunk. Select from 2-4 ports per trunk.
Port Statistics Use the Port Statistics menu to display Etherlike or RMON statistics for any port on the switch. Select the required port. The statistics displayed are indicated in the following figure and table. Etherlike Statistics Etherlike Statistics display key statistics from the Ethernet-like MIB for each port. Error statistics on the traffic passing through each port are displayed.
RMON Statistics RMON Statistics display key statistics for each port from RMON group 1. (RMON groups 2, 3 and 9 can only be accessed using SNMP management software.) The following screen displays overall statistics on traffic passing through each port. RMON statistics provide access to a broad range of statistics, including a total count of different frame types passing through each port. Values displayed have been accumulated since the last system reboot. Figure 3-42.
Parameter Description Collisions The best estimate of the total number of collisions on this Ethernet segment. 64 Byte Frames The total number of frames (including bad packets) received and transmitted that were 64 octets in length (excluding framing bits but including FCS octets). 65-127 Byte Frames The total number of frames (including bad packets) received and transmitted that were between 65 and 127 octets in length inclusive (excluding framing bits but including FCS octets).

APPENDIX A. TROUBLESHOOTING This appendix describes problems potentially encountered when using Digital Networks WebView and presents suggested solutions for correcting these problems. Troubleshooting Cannot Connect to the Switch If you attempt to connect to the switch and the main window does not appear, make sure that the correct IP address is entered in the URL field of the browser. • Check the network connections of both your workstation and the switch.
Frequently Asked Questions Can I Open More Than One Window for Same Switch? Yes. You can start multiple browser sessions with the switch at once. Will Network Congestion Prevent Use of Digital Networks WebView? It could. If there is significant network delay after a configuration command is issued, the system could time out. In addition, excessive delays when gathering switch statistics could interfere with the accuracy of performance statistics.
