Parameter
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.
By default, committed-burst-size is half of committed-information-rate,
excess-burst-size is 0, and queue-length is 50.
Description
Use the gts command to configure traffic shaping for a behavior.
Use the undo gts command to delete traffic shaping for a behavior.
A policy in which shape is used on an interface can only be applied in the outbound
direction of the interface.
Application of class-based GTS policy including shape policy on an interface will cause
the previously configured qos gts command ineffective.
If this command is frequently configured on the same traffic behavior, the last
configuration will overwrite the previous ones.
Related command: qos policy, traffic behavior, and classifier behavior.
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.
