Chapter 48: Port-based and Tagged VLAN Commands

SWITCHPORT TRUNK NATIVE VLAN
Syntax
switchport trunk native vlan vid |none
Parameters
vid
Specifies the VID of the VLAN that will act as the default VLAN for
all ingress and egress untagged packets on the tagged port. You
can enter just one VID.
none
Reestablishes the Default_VLAN as the native VLAN of the port.
This is equivalent to the NO form of this command.
Mode
Port Interface mode
Description
Use this command to designate native VLANs for tagged ports. The native
VLAN of a tagged port specifies the appropriate VLAN for ingress
untagged packets. A tagged port can have only one native VLAN, and the
VLAN must already exist on the switch.
Note
You cannot assign a native VLAN to a port that is already a tagged
member of that VLAN because a port cannot be both a tagged and
untagged member of the same VLAN.
Confirmation Command
“SHOW RUNNING-CONFIG” on page 130
Examples
This example designates VLAN 17 as the native VLAN for tagged port 15:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.15
awplus(config-if)# switchport mode trunk
awplus(config-if)# switchport trunk native vlan 17
