Chapter 14 Configuring VLANs
Displaying VLANs
To delete an extended-range VLAN, use the no vlan vlan-id global configuration command.
The procedure for assigning static-access ports to an extended-range VLAN is the same as for
normal-range VLANs. See the “Assigning Static-Access Ports to a VLAN” section on page 14-11.
This example shows how to create a new extended-range VLAN (when the EI is installed) with all
default characteristics, enter config-vlan mode, and save the new VLAN in the switch startup
configuration file:
Switch(config)# vtp mode transparent
Switch(config)# vlan 2000
Switch(config-vlan)# end
Switch# copy running-config startup config
Displaying VLANs
Use the show vlan privileged EXEC command to display a list of all VLANs on the switch, including
extended-range VLANs. The display includes VLAN status, ports, and configuration information. To
view normal-range VLANs in the VLAN database (1 to 1005,) use the show VLAN configuration
command (accessed by entering the vlan database privileged EXEC command). For a list of the VLAN
IDs on the switch, use the show running-config vlan privileged EXEC command, optionally entering a
VLAN ID range.
Table 14-3 lists the commands for monitoring VLANs.
For more details about the show command options and explanations of output fields, refer to the
command reference for this release.
