1. OVERVIEW Enterasys WebView Description This user guide describes Enterasys WebView, a web browser-based utility which allows you to remotely configure and manage Enterasys Networks products, including the VH-2402S/VH-2402S2 stackable switches. There is no software to install as Web management capability is built into the unit’s VH-SMGMT/VH-SMGMT2 Management Module. -
Page 8: Conventions
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. -
Page 9: Using Web-Based Management
Setting an IP Address The IP address for the switch in the stack containing the management agent must be set before it can be managed with Enterasys WebView. The switch IP address may be automatically set using BootP protocol, in which case the actual address assigned to the switch must be known. -
Page 10: Setting A Default Gateway
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 Enterasys WebView from a remote network or across the Internet. -

Page 12: Enterasys Webview User Interface
Enterasys WebView User Interface The Enterasys 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 Enterasys WebView user interface. The user interface is divided into four distinct areas as described in Table 2-1. - Page 13 Table 2-1. Areas of the User Interface Area Function Displays the Enterasys Networks logo. Selecting this area takes you directly to the Enterasys Networks Web site. Presents a graphical near real-time image of the front panel of the selected switch. This area displays the switch’s ports and expansion modules, showing port activity, duplex mode, or flow control, depending on the specified mode.

(If for some reason your password is lost, or you cannot gain access to the system’s configuration program, contact your Enterasys distributor for assistance.) Change Password This password is for the system Administrator, with access privilege of Read/Write for all screens. -
Page 23: Firmware Upgrade Options
Use the Web Upload Management menu to load software updates into the switch. The upload file should be an VH-2402S/VH-2402S2 binary file from Enterasys; otherwise the agent will not accept it. The success of the upload operation depends on the quality of the network connection. After uploading the new software, the agent will automatically restart itself. -
Page 24: Tftp Download Management
Use the TFTP Download Management menu to load software updates into the switch. The download file should be an VH-2402S/VH-2402S2 binary file from Enterasys; otherwise the agent 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. -
Page 25: Configuration Save And Restore
Use the Configuration Save&Restore 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. -
Page 26: Address Table Configuration
All entries, sorted by address or VLAN ID. Address Table Sort The system displays the MAC address of each node, the switch unit and port whose address table includes this MAC address, the associated VLAN(s), and the address status (i.e., dynamic or static). -
Page 27: 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, STA compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network. -
Page 28: Spanning Tree Information
(i.e., listening to learning to forwarding). The number of the port on this switch that is closest to the root. This switch communicates with the root device through this port. If there is no root port, then this switch has been accepted as the root device of the spanning tree network. - Page 29 • A port on a network segment with no other STA- compliant bridging device is always forwarding. • If two ports of a switch are connected to the same segment and there is no other STA device attached to this segment, the port with the smaller ID forwards packets and the other is blocked.

Page 32: Sta Port Configuration
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., lowest value) will be configured as an active link in the spanning tree. -
Page 33: Configuring Bridge Mib Extensions
(Refer to the Address Table Configuration on page 19.) Configurable This switch allows you to override the default PVID setting (Port PVID Tagging VLAN ID used in frame tags) and its egress status (VLAN- Tagged or Untagged) on each port. (Refer to VLAN Port Configuration on page 37.) -
Page 34: Bridge Settings
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. -
Page 35: Priority
Priority IEEE 802.1p defines up to 8 separate traffic classes. This switch supports Quality of Service (QoS) by using two priority queues, with strict priority 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. -
Page 36: Port Traffic Class Information
Port Traffic Class Information This switch provides two priority levels with strict priority queuing for port egress. This means that any frames with a default or user priority from 0~3 are sent to the low priority queue “0” while those from 4~7 are sent to the high priority queue “1”... -

Page 44: Igmp Multicast Filtering
This switch uses IGMP (Internet Group Management Protocol) to query for any attached hosts who want to receive a specific multicast service. The switch looks up the IP Multicast Group used for this service and adds any port which received a similar request to that group. It then propagates the service request on to any neighboring multicast switch/router to ensure that it will continue to receive the multicast service. -
