FCoE overview 1 In addition to FCoE capabilities, the Brocade 8000 switch also implements complete Fibre Channel Protocol (FCP) and Fiber Channel Forwarding (FCF) capabilities and delivers Advanced Fabric Services found in other Brocade FC switches. FIGURE 2 Brocade 8000 switch port side with CEE (blue) and FC (red) ports Figure 3 shows a logical view of the Brocade 8000 switch. There are two independent switches, one for CEE and the other for FC. There are six embedded FCoE virtual ports bridging the two switches. Each of these is a 10-Gigabit FCoE port. The Fabric OS has FCoE-specific CLI commands for the configuration and management of these FCoE ports. FCoE ports differ from the usual concept of a port in a Brocade switch. FCoE ports are embedded and are not directly associated with an external physical port on the switch. Configuration of the FCoE ports through the regular Fabric OS FC CLI is disabled; only the Fabric OS fcoe CLI commands can be used to configure and manage these ports. The FCoE ports are displayed as "ports" in some show command displays. The data displayed for a single FCoE port is the sum of the individual ports comprising the FCoE port. CEE statistics are not shown for the FCoE ports. NOTE In the Fabric OS CLI the FCoE ports can be enabled or disabled; there is no other configuration required. Each of the embedded FCoE ports is used explicitly for FCoE VF_port service and provides four MAC addresses and flow isolation for up to four flows per FCoE port.

FCoE overview
1
In addition to FCoE capabilities, the Brocade 8000 switch also implements complete Fibre Channel
Protocol (FCP) and Fiber Channel Forwarding (FCF) capabilities and delivers Advanced Fabric
Services found in other Brocade FC switches.
FIGURE 2

Figure 3
shows a logical view of the Brocade 8000 switch. There are two independent switches,
one for CEE and the other for FC. There are six embedded FCoE virtual ports bridging the two
switches. Each of these is a 10-Gigabit FCoE port. The Fabric OS has FCoE-specific CLI commands
for the configuration and management of these FCoE ports.
FCoE ports differ from the usual concept of a port in a Brocade switch. FCoE ports are embedded
and are not directly associated with an external physical port on the switch. Configuration of the
FCoE ports through the regular Fabric OS FC CLI is disabled; only the Fabric OS
fcoe
CLI commands
can be used to configure and manage these ports.
The FCoE ports are displayed as “ports” in some
show
command displays. The data displayed for a
single FCoE port is the sum of the individual ports comprising the FCoE port. CEE statistics are not
shown for the FCoE ports.
NOTE
In the Fabric OS CLI the FCoE ports can be enabled or disabled; there is no other configuration
required.
Each of the embedded FCoE ports is used explicitly for FCoE VF_port service and provides four MAC
addresses and flow isolation for up to four flows per FCoE port.

The FCoE VF_ports provide FC services to FCoE initiators and targets, as well as an FCoE-to-FC
bridging service that allows FCoE initiators to access FC targets and conversely, allows FC targets to
access FCoE initiators.
