Switch> show vlan dot1q tag native
dot1q native vlan tagging is disabled
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. 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.
This is an example of output from the show vlan private-vlan command:
Switch> show vlan private-vlan
