Table 16. Applying a DCB map to an Ethernet port
Step Task Command Command Mode
1
Enter interface configuration
mode on an Ethernet port.
interface
{tengigabitEthernet slot/
port fortygigabitEthernet
slot/port}
CONFIGURATION
2
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
Dell(config-if-te-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.
Table 17. Configuring PFC without a DCB Map
Step Task Command Command Mode
1 Enter interface configuration
mode on an Ethernet port.

CONFIGURATION
2 Enable PFC on specified
priorities. Range: 0-7. Default:
None.
Separate priority values with a
comma. Specify a priority
range with a dash, for
example: pfc priority 3,5-7

using the pfc priority
command on an interface
on which a DCB map has
been applied or which is
already configured for
