Chapter 59: Port-based and Tagged VLAN Commands

NO SWITCHPORT TRUNK NATIVE VLAN
Syntax
no switchport trunk native vlan
Parameters
None
Mode
Port Interface mode
Description
Use this command to reestablish the Default_VLAN as the native VLAN of
tagged ports. The native VLAN of a tagged port specifies the appropriate
VLAN for ingress and egress untagged packets. A tagged port can have
only one native VLAN.
Note
This command will not work if the tagged port is already a tagged
member of the Default_VLAN because a port cannot be both a
tagged and untagged member of the same VLAN.
Confirmation Command
“SHOW RUNNING-CONFIG” on page 166
Example
This example reestablishes the Default_VLAN as the native VLAN for
tagged ports 18 and 19:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.18,port1.0.19
awplus(config-if)# no switchport trunk native vlan
