vlan dot1q tag native
vlan dot1q tag native
Use the vlan dot1q tag native global configuration command on the switch stack or on a standalone
switch to enable tagging of native VLAN frames on all IEEE 802.1Q trunk ports. Use the no form of this
command to return to the default setting.
vlan dot1q tag native
no vlan dot1q tag native
Syntax Description This command has no arguments or keywords.
Defaults The IEEE 802.1Q native VLAN tagging is disabled.
Command Modes Global configuration
Command History
Usage Guidelines When enabled, native VLAN packets going out all IEEE 802.1Q trunk ports are tagged.
When disabled, native VLAN packets going out all IEEE 802.1Q trunk ports are not tagged.
You can use this command with the IEEE 802.1Q tunneling feature. This feature operates on an edge
switch of a service-provider network and expands VLAN space by using a VLAN-in-VLAN hierarchy
and tagging the tagged packets. You must use IEEE 802.1Q trunk ports for sending packets to the
service-provider network. However, packets going through the core of the service-provider network
might also be carried on IEEE 802.1Q trunks. If the native VLANs of an IEEE 802.1Q trunks match the
native VLAN of a tunneling port on the same switch, traffic on the native VLAN is not tagged on the
sending trunk port. This command ensures that native VLAN packets on all IEEE 802.1Q trunk ports are
tagged.
For more information about IEEE 802.1Q tunneling, see the software configuration guide for this
release.
Examples This example shows how to enable IEEE 802.1Q tagging on native VLAN frames:
Switch# configure terminal
Switch (config)# vlan dot1q tag native
Switch (config)# end
You can verify your settings by entering the show vlan dot1q tag native privileged EXEC command.
