• scheduler — schedules priority trac in port queues.
dcb-enable
Enable data center bridging.
Syntax
dcb enable
To disable DCB, use the no dcb enable command.
Defaults none
Command Modes CONFIGURATION
Command History
Version 9.2(0.0) Introduced on the M I/O Aggregator.
Version 8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information DCB is not supported if you enable link-level flow control on one or more interfaces.
dcb-policy 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
9.3(0.0) Introduced on the MXL platform.
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.
