Configuring QinQ

QinQ must be configured on all the devices and ports participating in the
provider bridge. Typically, customer facing ports are configured as untagged
members of S-VLANs and provider facing ports are configured as tagged
members of S-VLANs. Per the IEEE 802.1ad specification, there is no condition
binding port types (customer or provider) to untagged or tagged S-VLAN
memberships. Therefore, when configuring QinQ tunnelling on the switch,
you would first configure per-port S-VLAN membership (tagged or untagged),
and then configure the port type as 'customer-network' or 'provider-network'
depending on the device to which the switch port is connected.
A customer-network port can receive S-VLAN tagged frames if the customer
and provider agree upon the S-VID association for that customer and the
customer device is capable of sending S-VLAN tagged frames.

General Configuration Steps

To configure QinQ, you would take the following steps on all participating
provider switches (see the following sections for details and refer to page 7-15
for a configuration example):
1. Enable QinQ on the device, selecting the appropriate qinq mode (svlan or
mixed vlan mode).
2. Save the configuration and reboot the switch.
3. Configure S-VLANs and assign per port VLAN membership.
4. Configure port-types for all of the switch ports that carry QinQ traffic
across the network.
5. (Optional) Verify the configuration (see "Displaying QinQ Config and
Status" on page 7-22).
A reboot is required to enable/disable QinQ operations on the switch. When
moving between qinq modes (qinq mixedvlan to qinq svlan or vice versa), the
switch boots up with a default configuration for the new qinq mode and the
configuration parameters of the current mode will be erased out. Refer to
"Updating QinQ Configurations" on page 7-20 for details.
