Configuring Weighted Fair VoIP Queuing (WFVQ)

Weighted Fair VoIP Queuing (WFVQ) combines weighted fair queuing (WFQ) for data streams
and priority VoIP queuing to provide the real-time response time that is required for VoIP.
WFQ is applied to data streams to provide fair bandwidth distribution among different data
streams, with faster response times for shorter packets that are typical for interactive
applications such as telnet. Priority VoIP queuing is applied to VoIP bearer and signaling traffic.
WFVQ is the default queuing mode for all Serial interfaces and all Fast Ethernet interfaces for
which traffic-shaping is enabled. To disable WFVQ, you must enable another queuing mode,
using either the voip-queue or the priority-queue command in interface context. To
re-enable WFVQ, use the fair-voip-queue command in interface context. WFVQ is the
recommended queuing mode.
Note:
There is no no form of the fair-voip-queue command. If you enter the
Note:
command no fair-voip-queue, it will actually enable WFVQ if WFVQ is not
already enabled.
Use the following commands to set the WFVQ queuing parameters.
Use the voip-queue-delay command to set the maximum query delay. To determine
●
the queue size you currently have, use the show queueing command.
Use the fair-queue-limit command to specify the maximum number of packets that
●
can be queued in the weighted fair queue. The upper and lower limits of this command
depend on the amount of bandwidth configured for the interface.
Note:
This command should generally be used only for troubleshooting.
