CLI Guide

Version Description
9.3 (0.1) Introduced on S6000, S4810, and S4820T.
Usage Information
PFC and ETS are enabled by default on the interfaces when DCB is globally enabled
(refer to dcb enable). In some network topology, you may want to disable PFC on
an interface and apply link level flow control; Similarly you may want to disable ETS
on an interface and apply QoS bandwidth configurations.
Limitations
• “dcb-map” CLI on interface is mutually exclusive to “no dcb ets enable” and
“no dcb pfc enable”.
• “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
