Create a CoS classifier for a traffic class that will use PFC:

user@switch# set classifiers ieee-802.1 pfc-class import default
Configure this traffic class (pfc-class) to use forwarding class

user@switch# set classifiers ieee-802.1 pfc-class forwarding-class af2 loss-priority low

Bind the classifier to all interfaces of the FCoE VLAN:

Set a scheduler for this queue, allocating at least 20 percent of the buffer:
