Chapter 42 Configuring PFC QoS

PFC QoS Configuration Guidelines and Restrictions

•For these commands, PFC QoS applies identical configuration to all LAN ports controlled by the same application-specific integrated circuit (ASIC):

–rcv-queue random-detect

–rcv-queue queue-limit

–wrr-queue queue-limit

–wrr-queue bandwidth (except Gigabit Ethernet LAN ports)

–priority-queue cos-map

–rcv-queue cos-map

–wrr-queue cos-map

–wrr-queue threshold

–rcv-queue threshold

–wrr-queue random-detect

–wrr-queue random-detect min-threshold

–wrr-queue random-detect max-threshold

•Configure these commands only on physical ports. Do not configure these commands on logical interfaces:

–priority-queue cos-map

–wrr-queue cos-map

–wrr-queue random-detect

–wrr-queue random-detect max-threshold

–wrr-queue random-detect min-threshold

–wrr-queue threshold

–wrr-queue queue-limit

–wrr-queue bandwidth

–rcv-queue cos-map

–rcv-queue bandwidth

–rcv-queue random-detect

–rcv-queue random-detect max-threshold

–rcv-queue random-detect min-threshold

–rcv-queue queue-limit

–rcv-queue cos-map

–rcv-queue threshold

PFC3 Guidelines

•With Release 12.2(18)SXE and later releases, all versions of the PFC3 support QoS for IPv6 unicast and multicast traffic.

•To display information about IPv6 PFC QoS, enter the show mls qos ipv6 command.
