2Apply the DCB map on the Ethernet port to
configure it with the PFC and ETS settings in
the map; for example:
Dell# interface tengigabitEthernet 0/0
Dell(config-if-te-0/0)# 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

pfc priority command on an
