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. Converged data center services 1451
