Configure FIP snooping, an FCoE-trusted port, and PFC on the switch:
NOTE: The configuration of PFC includes two different
configuration statements:
ieee-802.1 (Congestion Notification)—Use to configure the congestion
notification profile.
ieee-802.1—Use to configure the CoS classifier.
Enable FIP snooping on the VLAN and modify the FC-MAP value to match the
1.
FC-MAP value being used by the FCF:

Configure a congestion notification profile, specifying the name of the profile and

applying it to the traffic class that is indicated by the User Priority bits in the 802.1Q
tagged frame of an incoming packet:
NOTE: The ENode and the switch must use the same traffic class for
the FCoE traffic.
