with a VLAN membership of 23. Received untagged packets are processed on
VLAN 23. Received packets tagged with VLAN 23 are also accepted. Other
received tagged packets are discarded.
console(config)#interface gigabitethernet 1/0/8
console(config-if-Gi1/0/8)#switchport access vlan 23
The following example sets the PVID for interface Gi1/0/12 to VLAN ID 33.
Since VLAN 33 does not exist, it is automatically created.
