R3303-HP HSR6800 Routers ACL and QoS Command Reference
113
bandwidth bandwidth: Bandwidth for the RTP priority queue, in the range of 8 to 1000000 in kbps and
is a part of the maximum reserved bandwidth.
cbs burst: CBS in the range of 1500 to 2000000 bytes.
Usage guidelines
This command provides preferential services for delay-sensitive applications, such as real-time voice
transmission.
Set the bandwidth argument to a value greater than the total bandwidth that the real-time application
requires to allow bursty traffic. In addition, reserve 20% of the bandwidth for Layer 2 frame headers,
which are not taken into account in bandwidth allocation.
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.
Examples
# Configure RTP queuing on interface Serial 2/0/1: the RTP packets with even UDP destination port
numbers in the range 16384 to 32767 are assigned to the RTP queue when congestion occurs on the
outgoing interface, and the bandwidth for RTP packets is 64 kbps.
