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.
