vlan dot1q tag native
To enable tagging of native VLAN frames on all IEEE 802.1Q trunk ports, use the vlan dot1q tag native
command in global configuration mode. To return to the default setting, use the no form of this command.

Usage Guidelines
When enabled, native VLAN packets going out of all IEEE 802.1Q trunk ports are tagged.
When disabled, native VLAN packets going out of 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 device
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 device, 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:
Device# configure terminal
Device (config)# vlan dot1q tag native
Device (config)# end
You can verify your settings by entering the show vlan dot1q tag native privileged EXEC command.
