CLI Guide

• “pfc priority” CLI is mutually exclusive to “no dcb pfc enable”
command.
• Deprecated CLI “dcb-policy input” and “no dcb pfc enable” cannot
coexist at interface level.
• Deprecated CLI “dcb-policy output” and “no dcb ets enable” cannot
coexist at interface level.
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.
Command Modes INTERFACE mode
Supported Modes Full–Switch
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%
