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: 1-4094)
new
-
vlan
- The new VLAN ID. (Range: 1-4094)
Default Setting
Disabled
Command Mode
Interface Configuration (Ethernet)
Command Usage
◆
If the next switch upstream does not support QinQ tunneling, then use this
command to map the customer’s VLAN ID to the service provider’s VLAN ID for
the upstream port. Similarly, if the next switch downstream does not support
QinQ tunneling, then use this command to map the service provider’s VLAN ID
to the customer’s VLAN ID for the downstream port. Note that one command
maps both the
original-vlan
to
new-vlan
for ingress traffic and the
new-vlan
to
original-vlan
for egress traffic on the specified port.
For example, assume that the upstream switch does not support QinQ
tunneling. If the command
switchport vlan-translation 10 100
is used to map
VLAN 10 to VLAN 100 for upstream traffic entering port 1, and VLAN 100 to
VLAN 10 for downstream traffic leaving port 1, then the VLAN IDs will be
swapped as shown below.
