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 ISL or 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.

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.
