end-port-number >. If this command is frequently used under a class, the last
configuration will overwrite the previous ones.
Related command: traffic classifier.
Example
# Define the match rule of class1 as matching the packets whose RTP port number is
the even UDP port number between 16384 and 32767.

2.5.24 lr
Syntax
lr cir committed-information-rate [ cbs committed-burst-size [ ebs excess-burst-size] ]
undo lr
View
Traffic behavior view
Parameter
committed-information-rate: CIR in the range 8000 to 155,000,000 bps.
committed-burst-size: CBS in the range 15,000 to 155,000,000 bits. When the CIR
value is less than 30,000, the default CBS value is 15,000; when the CIR value is
greater than 30,000, the default CBS value is half of the CIR value.
excess-burst-size: EBS in the range 0 to 155,000,000 bits. It defaults to 0, meaning
only one token bucket is used for policing.
Description
Use the lr command to configure LR.
Use the undo lr command to disable LR.
By default, LR is disabled.
LR is different from GTS in the sense that the former is functioning at the link layer
whereas the latter is functioning at the IP layer.
Related command: display traffic policy interface.
Example
# For the specified behavior, set CIR to 38400 bps and CBS to 76800 bits. This allows
bursty traffic twice the CIR to pass at the first time. After that, traffic smaller than 38400
bps is sent and traffic larger than 38400 bps is put in queues.
