Parameters
dcb-buer-
threshold

prole-name Enter the name of the prole, which can be a string of up to 32 characters in
length.
stack-unit all Enter the stack unit identication. Indicates the specic the stack unit or units.

Version Description
9.9(0.0) Introduced on the M I/O Aggregator and the FN I/O Aggregator.
Usage Information You can congure up to a maximum of four lossless (PFC) queues. By conguring four lossless queues, you
can congure four dierent priorities and assign a particular priority to each application that your network is
used to process. For example, you can assign a higher priority for time-sensitive applications and a lower
priority for other services, such as le transfers. You can congure the amount of buer space for each
priority and the pause or resume thresholds for the buer. This method of conguration enables you to
manage and administer the behavior of lossless queues.

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.
