R2511-HP MSR Router Series ACL and QoS Command Reference(V5)

166
end-port max-dest-port: Upper threshold for destination UDP port numbers, in the range of 2000 to
65535. The value of the max-dest-port argument cannot be smaller than that of the min-dest-port
argument.
bandwidth: Specifies the RTP priority queue bandwidth in the range of 8 to 1000000 kbps.
cbs committed-burst-size: CBS in the range of 1500 to 2000000 bytes. The default is 55550 bytes.
Usage guidelines
With the FR class configured with RTPQ applied to a PVC, an SP queue is established on the PVC, and
the packets destined to the UDP ports within the port range specified in RTPQ are assigned to the RTP
priority queue. When congestion occurs to the PVC, packets in the RTP priority queue are transmitted
preferentially within the configured bandwidth. When no congestion occurs to the PVC, packets
destination to the UDP ports within the specified range can be transmitted using the available bandwidth
of the PVC. The UDP port range for VoIP is generally configured as 16384 to 37267.
Examples
# Apply RTPQ to the FR class test1 and set the RTP priority queue length to 20 kbps.

traffic-shaping adaptation
Use traffic-shaping adaptation to enable FRTS adaptation.
Use undo traffic-shaping adaptation to disable this function.
Syntax
traffic-shaping adaptation { becn percentage | interface-congestion number }
undo traffic-shaping adaptation { becn | interface-congestion }
Default
FRTS adaptation is enabled for traffic with the BECN flag, and 25% of the total traffic is regulated every
time.

Default command level
2: System level
Parameters
becn: Regulates the traffic of packets with the BECN flag.
percentage: Percentage of the regulated traffic to the total traffic, in the range of 1 to 30. This argument
is 25 by default.
interface-congestion: Performs traffic regulation according to the number of packets in the output queues
on the interface.
number: Number of packets in the output queue of the interface, in the range of 1 to 40.
