Usage
Information
Use the pfc priority command to configure PFC operation on an Ethernet
interface for specified CoS traffic without using a DCB map in a network topology
that uses the default ETS setting (assigns equal bandwidth to each 802.1p priority).
The maximum number of lossless queues supported per port is two. If you
reconfigure the lossless queues for no-drop priorities in a DCB map and reapply
the map to the interface, traffic may be interrupted due to an interface flap (going
down and coming up).
The maximum number of lossless queues supported per port is two.
A PFC peer must support the configured priority traffic (as detected by DCBx) to
apply PFC.
