Enabling Fibre Channel Capability on the Switch
Enable the FC Flex IO module on an MXL 10/40GbE Switch or an M I/O Aggregator that you want to
configure as an NPG for the Fibre Channel protocol. When you enable Fibre Channel capability, FCoE
transit with FIP snooping is automatically enabled on all VLANs on the switch, using the default FCoE
transit settings.
Task Command Command Mode
Enable an MXL 10/40GbE Switch and M I/O
Aggregator with the FC Flex IO module for the
Fibre Channel protocol.

CONFIGURATION
Creating a DCB Map
Configure the priority-based flow control (PFC) and enhanced traffic selection (ETS) settings in a DCB
map before you apply them on downstream server-facing ports on an MXL 10/40GbE Switch or an M I/O
Aggregator with the FC Flex IO module.
Step Task Command Command Mode
1
Create a DCB map to specify PFC and ETS
settings for groups of dot1p priorities.

CONFIGURATION
2
Configure the PFC setting (on or off) and the
ETS bandwidth percentage allocated to traffic
in each priority group. Configure whether the
priority group traffic should be handled with
strict-priority scheduling. The sum of all
allocated bandwidth percentages must be
100 percent. Strict-priority traffic is serviced
first. Afterward, bandwidth allocated to other
priority groups is made available and allocated
according to the specified percentages. If a
priority group does not use its allocated
bandwidth, the unused bandwidth is made
available to other priority groups.
Restriction: You can enable PFC on a
maximum of two priority queues.
Repeat this step to configure PFC and ETS
traffic handling for each priority group, for
example: priority-group 0 bandwidth
60 pfc off priority-group 1
bandwidth 20 pfc onpriority-group 2
bandwidth 20 pfc on
priority-group 4
strict-priority pfc off
