is aggregated to form the committed burst size. Traffic is considered to be green-
colored up to the point at which the unused bandwidth does not exceed the
committed burst size.

qos-policy-output — creates a QoS output policy.
rate police — specifies traffic policing on the selected interface.
service-class buffer shared-threshold-weight
Create a service class and associate the threshold weight of the shared buffer with each of the queues
per port in the egress direction. A global buffer pool that is a shared buffer pool accessed by multiple
queues when the minimum guaranteed buffers for the queue are consumed can be configured on the
switch.

Syntax
[No] Service-class buffer shared-threshold-weight {[queue0
number] || [queue1 number] || [queue2 number] || [queue3
number] || [queue4 number] || [queue5 number] || [queue6
number] || [queue7 number]}
Parameters
buffer Define the shared buffer settings
shared-threshold-
weight
Specify the weight of a queue for the shared buffer space
queue 0 to queue
7
Specify the queue number to which the WRED parameters
apply
number Enter a weight for the queue on the shared buffer as a
number in the range of 1 to 11.
Default The default threshold weight on the shared buffer for each queue is 9. Therefore,
each queue can consume up to 66.67 percent of available shared buffer by default.

The following table describes the mapping between the threshold weight of the
shared buffer on the queue and the percentage of available shared buffer that is
used by the queue for each of the corresponding threshold weights of the shared
buffer:
