User–dened QoS map
You can override the default mapping by creating a QoS map.
Congure user–dened QoS map
1 Create a QoS map.
OS10(config)# qos-map traffic-class tc-q-map
2 Dene the set of trac 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 specic interface or on a 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 trac classied for a queue
1 Create a queuing type class-map to match queue 5.
OS10(config)# class-map type queuing q5
2 Dene the queue to match.
OS10(config-cmap-queuing)# match queue 5
Policing trac
Use policing to limit the rate of ingress trac ow. The ow can be all the ingress trac on a port or a particular ow assigned with a trac
class ID.
In addition, use policing to color the trac:
