S2D# priority-group 0 bandwidth 5 pfc off
S2D# priority-group 3 bandwidth 95 pfc on
S2D# priority-pgid 0 0 0 3 0 0 0 0
S2D# exit
*** Example #2 ***
Example for ports for Storage and Virtual Guest (VM) traffic with one Physical Network Adapter (2 Ports):
PFC control on QoS Class 3 (SMB) and Class 5 (Cluster)
S2D# configure
