Dell SmartFabric OS10 User Guide Release 10.5.3

Marking Traffic

After you classify the ingress traffic, you can set the value or change an existing value (remarking) for CoS or DSCP. Marking sets the IP precedence or IP DSCP value for traffic at ingress. The switch then uses the new marking to process the traffic.

Traffic class IDs identify the traffic flow when the traffic reaches egress for queue scheduling.

Mark traffic

1. Create a QoS type class-map to match the traffic flow.

   OS10(config)# class-map cmap-cos3
   OS10(config-cmap-qos)# match cos 3

2. Create a QoS type policy-map to mark it with a traffic class ID and assign it to the CoS flow.

   OS10(config)# policy-map cos3-TC3
   OS10(config-pmap-qos)# class cmap-cos3
   OS10(config-pmap-c-qos)# set qos-group 3
