Can We Configure Multiple Cos Values For Pfc ?

1.	Can We Configure Multiple Cos Values For Pfc ?
Answer» Yes, if you are asking you can use different COS values for PFC. PFC uses the IEEE 802.1p CoS values in the IEEE 802.1Q VLAN TAG to differentiate up to eight CoSs that can be subject to flow control independently. So on Nexus 5K,by default we have 8 lanes , 8 QOS-groups. Qos 6 and Qos 7 are reserved for control plane trafic and the rest 6 qos-groups can be assigned to drop-class or no-drop-class. By default FCoE is assigned COS 3. Yes, if you are asking you can use different COS values for PFC.
