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 1 as the native VLAN
of the tagged ports. The native VLAN is the repository for untagged frames
received by tagged ports.
When the default VLAN 1 is assigned to untagged ports, this command
removes the default VLAN 1 assignment from untagged ports and assigns
the default VLAN 1 to the native VLAN of untagged ports.
To reestablish the default VLAN 1 as the native VLAN, ports must be
tagged ports.
Confirmation Command
“SHOW RUNNING-CONFIG” on page 116
Example
This example reestablishes the default VLAN 1 as the native VLAN for
tagged ports 1.0.18 and 1.0.19:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.18,port1.0.19
awplus(config-if)# no switchport trunk native vlan
