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.
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
To apply the shared-threshold weight, specify the queue number
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.

Usage
Information
You can configure all the data queues. You can configure queues 0-7.
The following table describes the mapping between the threshold weight of the shared buffer on the
queue. It also shows the percentage of the available shared buffer used by the queues for each of the
corresponding threshold weights of the shared buffer:
