Configure PFC
PFC provides a pause mechanism that is based on the 802.1p priorities in ingress traffic. PFC prevents frame loss due to
network congestion. Configure PFC lossless buffers, and enable pause frames for dot1p traffic on a per-interface basis. Repeat
the PFC configuration on each PFC-enabled interface. PFC is disabled by default.
Decide if you want to use the default dot1p-priority-to-traffic class mapping and the default traffic-class-to-queue mapping. To
change the default settings, see PFC configuration notes.
Configuration steps:
1. Create PFC, dot1p traffic classes.
2. Configure ingress buffers for PFC traffic.
3. Apply a service policy and enable PFC.
4. (Optional) Configure the PFC shared buffer for lossless traffic.
Create PFC dot1p traffic classes
1. Create a network-qos class map to classify PFC traffic classes in CONFIGURATION mode, from 1 to 7. Specify the traffic
classes using the match qos-group command. QoS-groups map 1:1 to traffic classes 1 to 7; for example, qos-group 1
