The configuration enables EF traffic to be forwarded preferentially when congestion occurs.

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.
RTP priority queuing configuration example
Network requirements
Configure RTP priority queuing on interface Serial 1/1/1 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, whose maximum reserved bandwidth is configured as 70% of the available bandwidth.
Configuration procedure
# Enter system view.
<Sysname> system-view
# Enter interface view.
[Sysname] interface serial 1/1/1
# Configure the maximum reserved bandwidth as 70% of the available bandwidth on Serial 1/1/1.
[Sysname-Serial1/1/1] qos reserved-bandwidth pct 70
# Configure RTP priority queuing on interface Serial 1/1/1: the start port number is 16384, the end port
number is 32767, and 64 kbps of bandwidth is reserved for RTP packets. When congestion occurs to the
outgoing interface, RTP packets are assigned to the RTP priority queue.
