Addendum

If you configure more than one priority group as strict priority, the higher numbered priority queue is
given preference when scheduling data traffic.
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.

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
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.
