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.
