Users Guide

Decide if you want to use the default traffic-class-queue mapping or configure a nondefault traffic-class-to-queue mapping.
Traffic Class : 0 1 2 3 4 5 6 7
Queue : 0 1 2 3 4 5 6 7
If you are using the default traffic-class-to-queue map, no further configuration steps are necessary.
1.
Create a traffic-class-to-queue map in CONFIGURATION mode. Assign a traffic class (qos-group) to a queue in QOS-MAP mode
using 1-to-1 mappings. For a PFC traffic class, map only one
qos-group value to a queue number. A qos-group number is used
only internally to classify ingress traffic.
qos—map traffic-class tc-queue-map-name
queue {0-7} qos-group {0-7}
exit
2. Apply the traffic-class-queue map in SYSTEM-QOS or INTERFACE mode.
qos-map traffic-class tc-queue-map-name
Configure traffic-class to queue mapping for Z9332F-ON
The Z9332F-ON supports 12 queues per Ingress Traffic Manager (ITM) in the front-panel ports. The 12 queues are divided into eight
unicast (UC) and four multicast (MC) combinations. For multicast queues, MCQ index 0 to 2 are used for MC flows. MCQ index 3 sends
control packets from the CPU.
By default, multicast traffic map in the following order:
TC0-TC2 : Q0
TC3-TC5 : Q1
TC6-TC7 : Q2
You can map different traffic classes of UC and MC traffics to different queues, based on the requirement.
