Usage Guidelines

Usage Scenario

If both inner and outer tags of all packets transmitted on an interface need to be swapped, run the vlan-swap enable command on the interface. After VLAN tag swapping is configured on the interface, all its sub-interfaces are enabled with VLAN tag swapping automatically.

Configuration Impact

The vlan-swap enable command swaps the two VLAN tags of double-tagged packets and has no impact on single-tagged packets.

After BA classification based on 802.1p values is configured on a VLAN-swap-capable interface, BA classification is implemented based on the 802.1p values of the swapped outer VLAN tag.

Example

# Enable VLAN tag swapping on GE 0/1/1.
