Configuring VLAN Translation
QinQ tunneling uses double tagging to preserve the customer’s VLAN tags on traffic crossing the
service provider’s network. However, if any switch in the path crossing the service provider’s
network does not support this feature, then the switches directly connected to that device can be
configured to swap the customer’s VLAN ID with the service provider’s VLAN ID for upstream traffic,
or the service provider’s VLAN ID with the customer’s VLAN ID for downstream traffic.
This section describes commands used to configure VLAN translation.
switchport vlan-translation
This command maps VLAN IDs between the customer and service provider.
Syntax
switchport vlan-translation original-vlan new-vlan
no switchport vlan-translation original-vlan
original-vlan - The original VLAN ID. (Range: 1-4093)
new-vlan - The new VLAN ID. (Range: 1-4093)
