Example
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.

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:
