Configuring a CoS Scheduling Policy on Logical Tunnel Interfaces

You can configure a CoS scheduling policy on a logical tunnel interface (LT ifl). Logical tunnel interfaces can be used to terminate a pseudowire into a virtual routing and forwarding (VRF) instance. If an lt device is used to terminate a pseudowire, CoS scheduling policies can be applied on the lt interface to manage traffic entering the pseudowire. You accomplish this by configuring the hierarchical-scheduler attribute on the physical interface.


It is important to first commit the hierarchical-scheduler configuration under the logical tunnel physical interface (LT ifd), and subsequently add and commit the class-of-service configuration.


The output-traffic-control statement applies only to the LT ifl that is part of an L3 VRF instance.

The following example shows two pseudowires (pw1 and pw2) over lt-1/0/10. pw1 carries data, voice, and video traffic, and pw2 carries only data and voice traffic. All pseudowire traffic is restricted to 800m bps. The shaping rate for traffic over pw1 is 400m bps and the shaping rate for traffic over pw2 is 400m bps.
