Use the command to configure to apply Realtime Transport Protocol (RTP)

Priority Queuing.
Use the command to remove the application.
undo rtpq
The application of a FR class configured with RTPQ to a PVC results in the creation
of a strict priority queue on the PVC. Packets in the port range specified by RTPQ
of the destination UDP port will enter RTPQ. When congestion occurs in the virtual
circuit, the packets in the queue will be absolutely sent with preference without
exceeding the configured bandwidth. When congestion does not occur in the
virtual circuit, the RTP packets in the specified port range can occupy the available
bandwidth on the virtual circuit. Generally, the UDP port range used by VoIP can
be configured as from 16384 to 32767.
# Configure RTP priority queue on the FR class named test1 with a bandwidth of
20 kbps.
