Displaying VLANs
To display the VLAN assignments for all of the switch ports, do the
following:
1. Hover the cursor over the Switching tab.
The Switching tab is displayed. See Figure 20 on page 59.
2. From the Switching tab drop-down menu, select Virtual LANs.

The following fields are displayed:
 Vlan ID— VLAN identifier. The range is 2 to 4094. The VID of 1 is
reserved for the default VLAN. The VID cannot be the same as the
VID of an existing VLAN on the switch. If this VLAN is unique in
your network, its VID must also be unique. However, if this VLAN is
part of a larger VLAN that spans multiple switches, the VID value
for the VLAN must be the same on each switch. For example, if
you are creating a VLAN called Sales with a VID of 3 that spans
three switches, assign the Sales VLAN on each switch the same
VID value.
 Name— VLAN name. A name can be from 1 to 20 characters in
length. The first character must be a letter; it cannot be a number.
VLANs are easier to identify if their names reflect the functions of
their subnetworks or workgroups (for example, Sales or
Accounting). A name cannot contain spaces or special characters,
such as asterisks (*) or exclamation points (!). A name cannot be

is unique in your network, then its name must be unique as well. A
