Command History Release

Usage Guidelines
VLANs are created the first time that you enter the interface vlan vlan-id command for a particular
VLAN. The vlan-id corresponds to the VLAN-tag associated with data frames on an IEEE 802.1Q
encapsulated trunk or the VLAN ID configured for an access port.
If you delete a VLAN by entering the no interface vlan vlan-id command, the deleted interface is no
longer visible in the output from the show interfaces privileged EXEC command.
Note You cannot delete the VLAN 1 interface.
You can re-instate a deleted VLAN by entering the interface vlan vlan-id command for the deleted
interface. The interface comes back up, but the previous configuration is gone.
Examples
This example shows how to create a new VLAN with VLAN ID 23 and to enter interface configuration
mode:
Switch(config)# interface vlan 23
Switch(config-if)#
You can verify your setting by entering the
EXEC commands.
