Administrator Guide

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-1/1/1)# dcb-policy buffer-threshold test
dcb-policy dcb-buer-threshold (Global
Conguration)
Assign the dcb buer threshold policy on the stack ports. To apply the dcb buer threshold policy on the stack-units, use the conguration
mode. To apply on front-end ports, use the interface mode.
Syntax
dcb-policy buffer-threshold stack-unit all stack-ports all profile-name
Parameters
dcb-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.
stack-unit all Enter the stack unit identication. Indicates the specic the stack unit or units. Entering
all shows the status for all stacks.
stack-port all Enter the port number of a port in a switch stack.
Default None

Version Description
9.9(0.0) Introduced on the S6000 and the S6000–ON.
9.8(0.0) Introduced on the S4048-ON.

9.3(0.0) Introduced on the S4810 and S4820T 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 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.
