1 Apply the PFC service policy on an ingress interface or interface range in INTERFACE mode.
interface ethernet node/slot/port:[subport]
service-policy input type network-qos policy—map-name
interface range ethernet node/slot/port:[subport]-node/slot/port[:subport]
service-policy input type network-qos policy—map-name
2 Enable PFC without DCBX for FCoE and iSCSI trac in INTERFACE mode.
priority-flow-control mode on
Congure PFC
PFC is enabled on trac classes with dot1p 3 and 4 trac. The two trac classes require dierent ingress queue processing. In the
network-qos pp1 policy map, class cc1 uses customized PFC buer size and pause frame settings; class cc2 uses the default
settings.
