| 8.6.7 |  | Configuring LLQ |

To give priority to a class within a policy map, use the following command in policy-map class configuration mode:

> Router(config-pmap-c)#priority bandwidth

The following example shows the configuration for a policy-map that provides 80 kbps for the traffic class “llqtraffic”:

> Router(config)#policy-map prioritybw
> Router(config-pmap)#class class-default fair-queue
> Router(config-pmap-c)#class llqtraffic priority 80

The configuration and operation of LLQ can be verified with the following commands:

> Router#debug priority

The debug priority command displays priority queuing output if packets are dropped from the priority queue:

> Router#show queue interface-type interface-number

The show queue command displays queuing configuration and statistics for a particular interface:

> Router#show policy-map interface interface-name

The show policy-map interface command displays the configuration of all classes configured for all traffic policies on the specified interface. Displays if packets and bytes were discarded or dropped for the priority class in the traffic policy attached to the interface.
