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.

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
1. You cannot configure PFC
using the pfc priority
command on an interface on
which a DCB map has been
applied or which is already
configured for lossless
queues (pfc no-drop
queues command).
