Configuring WFQ
WFQ is enabled by default on physical interfaces with a bandwidth less than
2.048 Mbps. If it has been disabled, or to enable it on another interface, use
the interface command fair-queue [congestive-discard-threshold [dynamicqueues
[reservable-queues]]]. For example, the following commands enable
WFQ on the serial interface, set a CDT of 100, increase the number of flow
queues to 512, and reserve 10 queues for RSVP to use.
Router(config)#int s1/0/0:0
Router(config-if)#fair-queue 100 512 10
To change the size of the hold queue, use the hold-queue number {in | out}
interface command, as shown:
Router(config-if)#hold-queue 2000 out
To monitor the interface queues, use either show interface interface or show
queue interface:
Router#show interface s1/0/0:0
