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.

Syntax
priority-group
group-num
{bandwidth
percentage
| strict-
priority} pfc {on | off}
Parameters
priority-group
group-num
Enter the keyword
priority-group
followed by the
number of an 802.1p priority group. Use the
priority-
pgid
command to create the priority groups in a DCB map.
bandwidth
percentage
Enter the keyword
bandwidth
followed by a bandwidth
percentage allocated to the priority group. The range of valid
values is 1 to 100. The sum of all allocated bandwidth
percentages in priority groups in a DCB map must be 100%.
strict-priority
Configure the priority-group traffic to be handled with strict
priority scheduling. Strict-priority traffic is serviced first,
before bandwidth allocated to other priority groups is made
available.
pfc {on | off}
Configure whether priority-based flow control is enabled
(on) or disabled (off) for port traffic in the priority group.
