Applying a DCB Map in a Switch Stack
Apply the same DCB map with PFC and ETS configuration to all stacked ports in a switch stack. You
cannot apply different DCB maps to different stacked switches. This functionality is supported on the
platform.
To remove all PFC and ETS settings applied to stacked ports from the DCB map and reset PFC and ETS to
their default settings, use the
no dcb-map stack-unit all
command.
Task Command Command Mode
Apply the specified DCB map on all
ports of the switch stack.
