qos rtpq

Use qos rtpq to enable RTP queuing for RTP packets with even UDP destination port numbers in the
specified range on the interface/PVC.
Use undo qos rtpq to disable RTP queuing on the interface/PVC.
Syntax
qos rtpq start-port first-rtp-port-number end-port last-rtp-port-number bandwidth bandwidth [ cbs burst ]
undo qos rtpq
Default
RTP queuing is disabled on an interface or PVC.

2: System level
Parameters
start-port first-rtp-port-number: First UDP port number in the range of 2000 to 65535.
end-port last-rtp-port-number: Last UDP port number in the range of 2000 to 65535.
bandwidth bandwidth: Bandwidth for the RTP priority queue, in the range of 8 to 1000000 in kbps and
is a part of the maximum reserved bandwidth.
cbs burst: CBS in the range of 1500 to 2000000 bytes.
Usage guidelines
This command provides preferential services for delay-sensitive applications, such as real-time voice
transmission.
Set the bandwidth argument to a value greater than the total bandwidth that the real-time application
requires to allow bursty traffic. In addition, reserve 20% of the bandwidth for Layer 2 frame headers,
which are not taken into account in bandwidth allocation.
You must enable the rate limit function for the queuing function to take effect on these interfaces: tunnel
interfaces, subinterfaces, Layer 3 aggregate interfaces, HDLC link bundle interfaces, RPR logical
interfaces, and VT interfaces configured with PPPoE, PPPoA, or PPPoEoA.
