priority-flow-control priority

Use the priority-flow-control priority command in Datacenter-Bridging Config
mode to enable the priority group for lossless (no-drop) or lossy (drop) behavior on the
selected interface. Up to two lossless priorities can be enabled on an interface. The
administrator must configure the same no-drop priorities across the network in order to
ensure end-to-end lossless behavior.
The command has no effect on interfaces not enabled for PFC. VLAN tagging needs to be
turned on in order to carry the dot1p value through the network. Additionally, the
dot1pmapping to class of service must be set to one to one.
Default The default behavior for all priorities is drop.
