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.
Default By default, LR is disabled.
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.
