3. Configure default values for ingress buffers used for the network-qos class maps in POLICY-CLASS-MAP mode. pause (Optional) Change the default values for the ingress-buffer size that is reserved for the network-qos class-map traffic and the thresholds that are used to send XOFF and XON pause frames in kilobytes. pause [buffer-size kilobytes {pause-threshold kilobytes | resume-threshold kilobytes}] 4. Enable the PFC pause function for dot1p traffic in POLICY-CLASS-MAP mode. The dot1p values must be the same as the qos- group traffic class numbers in the class-map in Step 2. Enter a single dot1p value, from 1 to 7, a hyphen-separated range, or multiple dot1p values separated by commas. pfc-cos dot1p-priority 5. (Optional) Set the static and dynamic thresholds that are used to limit the shared buffers that are allocated to PFC traffic-class queues. Configure a static, fixed queue-limit (in kilobytes) or a dynamic threshold (weight 1-10; default 9) based on the available PFC shared buffers. queue-limit thresh-mode {static kilobytes | dynamic weight} 6. (Optional) Repeat Steps 2-4 to configure PFC on additional traffic classes. Apply service policy and enable PFC 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 traffic in INTERFACE mode. priority-flow-control mode on Configure PFC PFC is enabled on traffic classes with dot1p 3 and 4 traffic. The two traffic classes require different ingress queue processing. In the network-qos pp1 policy map, class cc1 uses customized PFC buffer size and pause frame settings; class cc2 uses the default settings.
