1834 CHAPTER 116: RTP PRIORITY QUEUE CONFIGURATION COMMANDS
View Interface view
Parameters pct percent: Percentage of the reserved bandwidth to the available bandwidth. It
is in the range 1 to 100 and the default value is 80.
Description Use the
qos reserved-bandwidth command to set the maximum reserved
bandwidth percentage.
Use the
undo qos reserved-bandwidth command to restore the default value.
Usually the bandwidth configured for the QoS queue is less than 80 percent of the
total bandwidth, considering that part of the bandwidth should be used for
controlling protocol packets, layer 2 frame headers and so on.
Caution should be taken in using this command to modify the maximum
preserved bandwidth.
Related commands: qos rtpq.
Examples # Set the maximum reserved bandwidth allocated for RTP priority queue to 70%
of the available bandwidth.

Parameters start-port first-rtp-port-number: Specifies the first UDP port number to initiate
RTP messages, in the range 2000 to 65535.
end-port last-rtp-port-number: Specifies the last UDP port number to initiate RTP
messages, in the range 2000 to 65535.
bandwidth bandwidth: Bandwidth for RTP priority queue, which is part of the
maximum reserved bandwidth in kbps, in the range 8 to 1000000.
cbs burst: Committed burst size, in the range 1500 to 2000000 in byte.
Description Use the
qos rtpq command to enable RTP queue feature on an interface so as to
reserve a real-time service for the RTP packets sent to some UDP destination port
ranges.
