dcb-map
Create a DCB map to configure priority flow control (PFC) and enhanced transmission selection (ETS) on Ethernet ports that support
converged Ethernet traffic. Apply the DCB map to an Ethernet interface.
Syntax dcb-map map-nameTo remove a DCB map from an ethernet interface, use the no dcb-map command.
Parameters
map-name Enter a DCB map name. The maximum number of alphanumeric characters is 32.
Defaults None.

Usage Information
A DCB map is a template used to configure DCB parameters and apply them on converged Ethernet interfaces.
DCB parameters include priority-based flow control (PFC) and enhanced traffic selection (ETS).
To display the PFC and ETS settings in DCB maps, enter the show qos dcb-map name command.
Use the dcb-map command to create a DCB map to specify PFC and ETS settings and apply it on Ethernet
ports. After you apply a DCB map to an interface, the PFC and ETS settings in the map are applied when the
Ethernet port is enabled. DCBx is enabled on Ethernet ports by default.
The dcb-map command is supported only on physical Ethernet interfaces.
To remove a DCB map from an interface, enter the no dcb-map map-name command in Interface
configuration mode.
You can enable or disable pfc mode on the DCB mode using the pfc mode on or pfc mode off command.
While removing a DCB map, ensure that the no dcb-map command is used on the interfaces that need a
configuration change. Entering the no dcb-map command globally or for a range of interfaces may result in
traffic loss and protocol session flaps running on the interfaces.
priority-pgid
Assign 802.1p priority traffic to a priority group in a DCB map.
