Apply the DCB map on the Ethernet port to
configure it with the PFC and ETS settings in the
map; for example:
Dell# interface tengigabitEthernet
1/1/1
Dell(config-if-te-1/1/1)# dcb-map
SAN_A_dcb_map1 Repeat Steps 1 and 2 to apply
a DCB map to more than one port.
You cannot apply a DCB map on an interface
that has been already configured for PFC using
thepfc priority command or which is
already configured for lossless queues (
pfc no-
drop queues command).

Configuring PFC without a DCB Map
In a network topology that uses the default ETS bandwidth allocation (assigns equal bandwidth to each
priority), you can also enable PFC for specific dot1p-priorities on individual interfaces without using a DCB
map. This type of DCB configuration is useful on interfaces that require PFC for lossless traffic, but do not
transmit converged Ethernet traffic.

CONFIGURATION
2 Enable PFC on specified priorities. Range: 0-7.
Default: None.
Maximum number of lossless queues
supported on an Ethernet port: 2.
Separate priority values with a comma. Specify
a priority range with a dash, for example: pfc
priority 3,5-7
