Set Inner and Outer CoS as a Policer Action

Set Inner and Outer CoS as a Policer Action
The Set Inner and Outer CoS as a Policer Action feature uses the police command to set the inner and
outer VLAN class of service (CoS) bits for QinQ traffic on the PRE2, PRE3, and PRE4. The 3-bit CoS
field is part of the VLAN tag and indicates the priority level of the frame. IEEE 802.1p establishes eight
levels of priority: 0 to 7
This feature polices the traffic on the inbound interface of the provider edge (PE) router where the
attachment VC terminates. Marking of frames using the set-cos-transmit and set-cos-inner-transmit
policing actions occurs on the outbound interface. Therefore, when configuring this feature, you must
attach a policy map that includes the both of these policing actions to an outbound interface, not to an
inbound interface.
The set-cos-transmit policing action sets the outer CoS bits whereas the set-cos-inner-transmit action
sets the inner CoS bits. To configure marking of both inner and outer CoS bits at the same time, you must
specify both the set-cos-transmit and set-cos-inner-transmit policing actions in a single police command.
You can specify these policing actions as conform, exceed, or violate actions.
The router supports simultaneous inner and outer CoS marking in single-rate and dual-rate policing
policies, and in hierarchical policies.

Dual Police Actions

The router allows you to specify dual actions for conforming, exceeding, and violating traffic, one line
at a time. After you provide the police rates, press Return to enter the policy-map-class-police
configuration mode. While in this mode, you can configure the dual conform, exceed, and violate actions
by entering an action keyword and action value, and pressing Return after each specified action. Valid
combinations of dual actions are:
•
•
•
The router allows only the dual action combinations listed above and does not do error checking for these
Note
actions.
For example, you can specify the first conform-action as set-frde-transmit and the second
conform-action as set-mpls-exp-imposition-transmit. If desired, you can then specify these same two
actions as the action for the first and second exceed actions and for the two violate actions.
