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:

shared-threshold-weight on the queue	% of available shared buffer that can be consumed by the queue.
0	No dynamic sharing; shared buffer = 0.
1	0.77%
2	1.54%
3	3.03%
4	5.88%
5	11.11%
6	20%
7	33.33%
8	50%
9	66.67%
10	80%
11	88.89%
