You can apply a DCB output policy with ETS configuration to all stacked ports in a
switch stack or an individual stacked switch. You can apply different DCB output
policies to different stack units.
NOTE: Please note that Dell Networking does not recommended to use this
command as it has been deprecated in the current 9.4.(0.0) release. A warning
message appears when you try to run this command indicating that you have
to use the
dcb-map
commands in the future.

queues {
1-2
}
To remove the configuration for the PFC buffer on all switches in the stack, use the
no dcb stack-unit all pfc-buffering pfc-port-count pfc-queues
command.
Parameters
pfc-port-count
{
1-56
}
Enter the pfc-port count. The range is 1 to 56.
pfc-queues

History
Version 9.2(0.0)
Introduced on the M I/O Aggregator. This command is
supported in Programmable-Mux (PMUX) mode only.
Version 8.3.16.1
Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
If you configure PFC on a 40GbE port, count the 40GbE port as four PFC-enabled
ports in the pfc-port number you enter in the command syntax.
To achieve lossless PFC operation, the PFC port count and queue number used for
the reserved buffer size that is created must be greater than or equal to the buffer
size required for PFC-enabled ports and lossless queues on the switch.
You must reload the stack or a specified stack unit (use the reload command in
EXEC Privilege mode) for the PFC buffer configuration to take effect.
