FCoE configuration tasks
There are several tasks related to FCoE configuration. The following list describes the high level
tasks in a suggested order:
• Quality of Service (QoS) configuration (optional)—If you intend to implement a specific QoS
scheme to prioritize data traffic, it is recommended that you finish your QoS configuration
before you begin port configuration. QoS values are referenced when you configure ports.
• LLDP-DCBX configuration (optional)—If you intend to implement DCBX, it is recommended that
you finish LLDP-DCBX configuration before you configure ports. LLDP-DCBX values are
referenced when you configure ports.
• DCB interface configuration (mandatory).
• Link Aggregation Group (LAG) configuration (mandatory)—Ports must be configured before they
can be placed into a LAG. The parameters applied to the LAG reflects on each port that is
member of the LAG.
• VLAN configuration (optional)—Port and LAG names are referenced in VLAN configuration, and
must be defined before you can successfully complete a VLAN configuration.
• Login group configuration (optional)—Login group configuration is not dependent on any of the
previous configurations. It can be done as a separate task.
Quality of Service configuration
As a general concept, Quality of Service (QoS) is a mechanism for classifying and scheduling data
traffic based on priority settings. QoS can be used to control traffic congestion, allocate bandwidth,
and carry data traffic with different characteristics over a common interface.
The following two configuration options are available:
• You can edit the DCB map. The DCB map defines priority and priority group tables that support
Enhanced Transmission Selection (ETS). ETS allows allocation of bandwidth to different traffic
classes. DCB maps also allow you to enable Priority Flow Control (PFC).
• You can create a traffic class map. A traffic class map can be used to map a specific class of
traffic to a specific Class of Service (CoS).
