Chapter12 Configuring VLANs
Displaying VLANs
Beginning in privileged EXEC mode, follow these steps to create an extended-range VLAN:
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 page12-10.
This example shows how to create a new extended-range VLAN 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 inform ation. To
view normal-range VLANs in the VLAN database (1 to 1005) u se 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.
Table12-3 lists the commands for monitoring VLANs.
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 vtp mode transparent Configure the switch for VTP transparent mode, disabling VTP.
Step3 vlan vlan-id Enter an extended-range VLAN ID and enter config-vlan mode. The
range is 1006 to 4094.
Step4 mtu mtu-size (Optional) Modify the VLAN by changing the MTU size.
Note Although all commands appear in the CLI help in config- vlan
mode, only the mtu mtu-size command is supported for
extended-range VLANs.
Step5 end Return to privileged EXEC mode.
Step6 show vlan id vlan-id Verify that the VLAN has been created.
Step7 copy running-config startup config Save your entries in the switch startup configuration file. To save
extended-range VLAN configurations, you need to save the VTP
transparent mode configuration and the extended-range VLAN
configuration in the switch startup configuration file. Otherwise, if the
switch resets, it will default to VTP server mode, and the extended-range
VLAN IDs will not be saved.
