CoS Scheduling Policy on Logical Tunnel Interfaces Overview
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.
This feature is supported on MIC and MPC interfaces.
