which is not used by any traffic that is traversing the network, 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.

Commands
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.

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.

queue can consume up to 66.67 percent of available shared buffer by default.
