Egress traffic classification
Egress traffic is classified into different queues based on the traffic-class ID marked on the traffic flow.
You can set the traffic class ID for a flow by enabling trust or by classifying ingress traffic and mark it with a traffic class ID
using a policy map. By default, the value of traffic class ID for all the traffic is 0.
The order of precedence for qos-map is:
1. Interface level map
2. System-qos level map
3. Default map
Table 37. Default mapping of traffic class ID to queue
Traffic class ID Queue ID
0 0
1 1
2 2
3 3
4 4
5 5
6 6
7 7
User–defined QoS map
You can override the default mapping by creating QoS map.
Configure user–defined QoS map
1. Create a QoS map
OS10(config)# qos-map traffic-class tc-q-map
2. Define the set of traffic class values mapped to a queue
OS10(config-qos-map)# queue 3 qos-group 0-3
3. Verify the map entries.
OS10# show qos maps type tc-queue
Traffic-Class to Queue Map: tc-q-map
Queue Traffic-Class
--------------------------
3 0-3
4. Apply the map on a specific interface or on system-qos (global) level.
● Interface level
OS10(conf-if-eth1/1/1)# qos-map traffic-class tc-q-map
● System-qos level
OS10(config-sys-qos)# qos-map traffic-class tc-q-map
Choose all traffic classified for a queue
