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 buffer-threshold (Global Configuration)
Assign the dcb buffer threshold policy on the stack ports. To apply the dcb buffer threshold policy on the stack-units, use the
configuration 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-buffer-
threshold
Configure the profile name for the DCB buffer threshold.
profile-name Enter the name of the profile, which can be a string of up to 32 characters in length.
stack-unit all Enter the stack unit identification. Indicates the specific 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
Command Modes CONFIGURATION mode

Version Description
9.3(0.0) Introduced on the MXL platform.
Usage Information You can configure up to a maximum of four lossless (PFC) queues. By configuring four lossless queues, you can
configure four different 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 file transfers. You can configure the amount of buffer space for each priority and the pause or
resume thresholds for the buffer. This method of configuration enables you to manage and administer the
behavior of lossless queues.
