This is an example of output from the show vlan internal usage command. It shows that VLANs 1025
and 1026 are being used as internal VLANs for Gigabit Ethernet routed ports 23 and 24 on stack
member
1. If you want to use one of these VLAN IDs, you must first shut down the routed port, which
releases the internal VLAN, and then create the extended-range VLAN. When you start up the routed
port, another internal VLAN number is assigned to it.
Switch> show vlan internal usage
