Qinq Configuration Commands; Nest - HP 6125G Command Reference Manual

QinQ configuration commands

Throughout this document, customer network VLANs (CVLANs), also called inner VLANs, refer to
•
the VLANs that a customer uses on the private network; and service provider network VLANs
(SVLANs), also called outer VLANs, refer to the VLANs that a service provider uses to carry VLAN
tagged traffic for customers.
Selective QinQ is achieved through QoS policies. For more information about QoS policy
•
configuration commands, see ACL and QoS Command Reference.

nest

Syntax
nest top-most vlan-id vlan-id
undo nest top-most
View
Traffic behavior view
Default level
2: System level
Parameters
vlan-id vlan-id: Specifies a VLAN tag ID, ranging from 1 to 4094.
Description
Use nest to add a VLAN nest action to a traffic behavior. If the traffic behavior already contains a VLAN
nest action, the new one overwrites the old one.
Use undo nest to remove the action.
The nest action enables a port to insert an outer VLAN tag in VLAN tagged traffic.
If a QoS policy contains a VLAN nest action, apply it only to the incoming traffic of a port, and you must
enable basic QinQ on the port first.
If this command is configured multiple times for the same traffic behavior, the last configured applies.
The nest action cannot be applied to a VLAN or globally.
Related commands: qos policy, traffic behavior, and classifier behavior (ACL and QoS Command
Reference).
Examples
# Create traffic behavior b1, and add the action of inserting outer VLAN tag 123.
<Sysname> system-view
[Sysname] traffic behavior b1
[Sysname-behavior-b1] nest top-most vlan-id 123
