Users 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 congure the amount of buer space to be allocated for each priority and 
the pause or resume thresholds for the buer. This method of conguration enables you to eectively manage and 
administer the behavior of lossless queues.
Example
Dell(conf-if-te-1/1/1)# dcb-policy buffer-threshold test
dcb-policy dcb-buer-threshold (Global 
Conguration)
Assign the dcb buer threshold policy on the stack ports. To apply the dcb buer threshold policy on the stack-units, use the conguration 
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-buer-
threshold
Congure the prole name for the DCB buer threshold
prole-name Enter the name of the prole, which can be a string of up to 32 characters in length.
stack-unit all Enter the stack unit identication. Indicates the specic 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.

9.3(0.0) Introduced on the S4810 and S4820T platforms.
Usage Information You can congure up to a maximum of four lossless (PFC) queues. By conguring four lossless queues, you can 
congure four dierent 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 congure the amount of buer space for each priority and the pause or 
resume thresholds for the buer. This method of conguration enables you to manage and administer the behavior 
of lossless queues.
