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
S6000 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.
