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 Fast 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
