Searching the Forwarding Database
Use the following procedures to search the forwarding database.
1. Enter the two-byte hexadecimal VLAN ID followed by the six byte hexadecimal MAC address in two-digit
groups separated by colons.
For example, 01:23:45:67:89:AB:CD:EF where 01:23 is the VLAN ID and 45:67:89:AB:CD:EF is the MAC
address.
2. Click Search.
If the address exists, that entry is displayed as the first entry in the table after the screen refreshes. The
entry is followed by the remaining (greater) MAC addresses. An exact match is required. If you click
Refresh, the MAC addresses with lower values are displayed again. fake
Managing VLANs
Adding Virtual LAN (VLAN) support to a Layer 2 switch offers some of the benefits of both bridging and routing.
Like a bridge, a VLAN switch forwards traffic based on the Layer 2 header, which is fast, and like a router, it
partitions the network into logical segments, which provides better administration, security and management
of multicast traffic.
A VLAN is a set of end stations and the switch ports that connect them. You may have many reasons for the
logical division, such as department or project membership. The only physical requirement is that the end
station and the port to which it is connected both belong to the same VLAN.
Each VLAN in a network has an associated VLAN ID, which appears in the IEEE 802.1Q tag in the Layer 2 header
of packets transmitted on a VLAN. An end station may omit the tag, or the VLAN portion of the tag, in which
case the first switch port to receive the packet may either reject it or insert a tag using its default VLAN ID. A
given port may handle traffic for more than one VLAN, but it can only support one default VLAN ID.
VLAN Configuration
Use the VLAN Configuration page to define VLAN groups stored in the VLAN membership table. Your switch
supports up to 3965 VLANs. VLAN 1 is the default VLAN of which all ports are members.
To display the VLAN Configuration page, click LAN > L2 Features> VLAN > VLAN Configuration in the
navigation tree.
