Abstract
In one embodiment, a network device is provided that includes a plurality of ports, where each port is associated with a plurality of traffic classes for prioritizing traffic received on the port. The network device further includes a packet buffer memory, an ingress traffic management engine, and an egress traffic management engine. The network device is configured to allow, for each port, concurrent operation of tail-drop and priority-based flow control (PFC) with respect to different traffic classes of the port.
