Command Reference
gts
Purpose Use the gts command to configure traffic shaping for a behavior.
Use the
undo gts command to delete traffic shaping for a behavior.
Syntax gts cir committed-information-rate [ cbs committed-burst-size [ ebs
excess-burst-size [ queue-length queue-length ] ] ]
undo gts
Parameters cir
committed-information-rate
CIR, in the range of 8000 to 155,000,000 bps. Note
that in policy embedding, the CIR specified in a child
policy could be less than 8 kbps.
cbs committed-burst-size
CBS, in the range of 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.
ebs excess-burst-size
EBS, in the range of 0 to 155,000,000 bits.
queue-length queue-length
The maximum length of a queue, in the range 1 to
1024.
Default By default, committed-burst-size is half of
committed-information-rate, excess-burst-size is 0, and
queue-length is 50.
Example Configure GTS for a behavior. The normal traffic is 38400 bps. Burst traffic twice of
the normal traffic can pass initially and later the traffic is transmitted normally when
the rate is less than or equal to 38400 bps. When the rate exceeds 38400 bps, the
traffic will enter the queue buffer and the buffer queue length is 100.
