FCoE services include:
FC fabric services for FCoE VN_port devices. FCoE VF_port services provide access to FCoE
VN_port devices similar to those provided by FC F_port to FC N_port devices.
FCoE-to-FC switching and translation services:
- FCoE servers to/from FC targets.
- FCoE targets to/from FC servers.
FCoE features include:
FIP—Solicited and unsolicited FCF advertisements (per June 10, 2008 version of T11-FC-BB5).
FCoE FLOGI.
VF_ports.
N_port ID virtualization (NPIV) on VF_ports, up to 1000 devices per FCF.
NOTE
NPIV is an FC facility allowing multiple N_port IDs to share a single physical N_port. This allows
multiple FC initiators to occupy a single physical port.
For FCoE ENodes, there is support for only directly-connected links.
Flow isolation.
Logical connectivity
Figure 2 shows a logical view of the Brocade 8000 CEE 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 as they are embedded ports
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 provide four MAC
addresses and flow isolation for up to four flows per FCoE port.
