You must enable the rate limit function for the queuing function to take effect on these interfaces: tunnel
interfaces, subinterfaces, HDLC link bundle interfaces, and VT/dialer interfaces configured with PPPoE,
PPPoA, PPPoEoA, PPPoFR, or MPoFR (frame relay traffic shaping is not enabled on the frame relay
interface).
RTP priority queuing configuration example
Network requirements
Configure RTP priority queuing on interface Serial 2/0 as follows:
The start port number is 16384, the end port number is 32767, and 64 kbps bandwidth is reserved for
RTP packets. When congestion occurs to the outgoing interface, RTP packets are assigned to the RTP
priority queue.
