Chapter 24 Configuring QoS

Configuring Quality of Service (QoS)

Step 6 Use the priority command to specify the priority percentage allocated to the traffic class assigned to the policy map. You can use the burst parameter to configures the network to accommodate temporary bursts of traffic.

Router(config-pmap-c)# priority percent 10

Step 7 Use the bandwidth command to specify the bandwidth available to the traffic class within the policy map. You can specify the bandwidth in kbps or by a percentage of bandwidth.

Router(config-pmap-c)# bandwidth percent 30

Step 8 Exit configuration mode.

Router(config-pmap-c)# end

Router#

Note You can use the show policy-map,show policy-map policy-map class class-name, or show

policy-map interface commands to verify your configuration.

Configuring Multiple Priority Queueing

Multiple priority queuing allows you to configure more than one class with priority percentage. The queue-number decides the ordering. The QoS group is serviced in the descending order starting with the highest queue number. This guarantees each of the queues its allocated bandwidth. This configuration has a higher latency on the lower priority queue like voice, due to servicing multiple traffic types on priority.

Restrictions

There is no provision to configure the priority level for a traffic class.

Complete the following steps to configure multiple priority queueing.
