Users Guide

although a DCB input policy is present, the peer-provided priorities become eective for buer
conguration. This method of conguration provides an easy and exible technique to accommodate both
administratively-congured and peer-congured priorities.
Example
Dell(conf)# qos-policy-buffer test
Dell(conf-qos-policy-buffer)#queue 0 pause no-drop buffer-size 128000
pause-threshold 103360 resume-threshold 83520
Dell(conf-qos-policy-buffer)# queue 4 pause no-drop buffer-size 128000
pause-threshold 103360 resume-threshold 83520
dcb-policy buer-threshold (Interface Conguration)
Assign the DCB policy to the DCB buer threshold prole on interfaces. This setting takes precedence over the global buer-
threshold setting.
Syntax
dcb-policy buffer-threshold profile-name
Parameters
buer-threshold Congure the prole name for the 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.
Default None
Command Modes INTERFACE mode

Version Description
9.7(0.0) Introduced on the S6000-ON.
9.3(0.0) Introduced on the S4810, S4820T, and S6000 platforms.
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 to be
allocated for each priority and the pause or resume thresholds for the buer. This method of conguration
enables you to eectively manage and administer the behavior of lossless queues.
Example
Dell(conf-if-te-1/1)#dcb-policy buffer-threshold test
dcb-policy dcb-buer-threshold (Global Conguration)
Assign the DCB policy to the DCB buer threshold prole on stack ports that applies globally throughout the system. This utility is
supported on the S4810 and platforms. This command is not supported on the S6000 platform because it does not contain stack
ports.
