currently in use.

takes you to the Basic Port Configuration tab, where

you can:

■Assign a name (or label) to the port

■Enable or disable the port

■Enable or disable flow control

■Configure the speed duplex settings

Accessing the Interface Without Using Discovery

The Discovery application works by automatically

detecting the IP address that is assigned to the

Switch, and then using that address to connect to the

Web interface. If you know the Switch’s IP address,

you can access the Web interface without using Dis-

covery.

This section describes how to access the interface

directly, without using Discovery.

Port Configuration Allows you to configure the Switch’s

port settings

VLANs Allows you to create VLAN groups,

add port members, and specify how

VLAN tagging is used

Trunking Allows you to set up and maintain

trunk membership for port groups

Traffic Monitoring Allows you to perform port traffic

monitoring on the Switch. To monitor

a port, you will also need a network

analyzer.

System Tools Contains tabs that allow you to:

■Restart and reset the Switch

■Back up and restore configuratio

■Upgrade the firmware

■Configure forwarding of BPDU

packets to support a spanning tree

topology

■Enable and disable 802.1p prioriti-

zation
