service-class buer shared-threshold-weight
Create a service class and associate the threshold weight of the shared buer 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
buer Dene the shared buer settings
shared-threshold-
weight
Specify the weight of a queue for the shared buer 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 buer as a number in the range of 1 to 11.
Default The default threshold weight on the shared buer for each queue is 9. Therefore, each queue can consume up to
66.67 percent of available shared buer by default.

You can congure all the data queues. You can congure queues 0-7.
The following table describes the mapping between the threshold weight of the shared buer on the queue. It also
shows the percentage of the available shared buer used by the queues for each of the corresponding threshold
weights of the shared buer:
