Parameters

start-port first-rtp-port-number: Specifies the start UDP port number in the range of 2000 to 65535.

end-port last-rtp-port-number: Specifies the end UDP port number in the range of 2000 to 65535.

bandwidth bandwidth: Specifies the maximum bandwidth allowed for the RTP priority queue, in the range of 8 to 1000000 kbps.

cbs committed-burst-size: Specifies the CBS in the range of 1500 to 2000000 bytes.

Usage guidelines

This command provides preferential service for delay-sensitive applications, such as real-time voice traffic transmission.

Set the bandwidth argument to a value greater than the required bandwidth for real-time applications to allow bursts of traffic.

Examples

# Enable RTPQ on GigabitEthernet 1/0/1 for RTP packets with a destination UDP port number in the range of 16384 to 32767.
