Description (partial)

Packet buffer utilization goes high under oversubscription condition.

When using ASR1001-X, ASR1002-X or ESP100/200 hardware with aggregate port-channel feature.     If there has been a QoS policy applied and removed from the port-channel interface which contains the "fair-queue" feature, we might see the packet buffer utilization goes high with oversubscribed traffic condition.   If the packet buffers utilization goes really high, then the important control protocols packets might get dropped.
