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.
