priority-flow-control priority
The
priority-flow-control priority
command is used in the Datacenter-Bridging Config mode in order to
enable the priority group for lossy (drop) or lossless (no-drop) behavior on the given interface. A
maximum of two lossless priorities may be enabled on a single interface. In order to ensure end-to-end
lossless behavior, the
administrator must configure the no-drop priorities to be the same across the
network.
The command does not have any effect on those interfaces not enabled for PFC. In addition, VLAN
tagging must be turned on to transmit the dot1p value through the network, while the setting of
dot1pmapping to class-of-service must be one-to-one.
The
no
command is used in the Datacenter-Bridging Config mode in order to enable lossy behavior for all
priorities on the given interface. Use of the command will have no effect, however, on those interfaces not
enabled for PFC or that have no lossless priorities configured.

Parameters
