Chapter 24 Configuring IP Storage
Configuring FCIP
The IPS module supports FCIP links that originate from a B port SAN extender device by implementing
the B access ISL protocol on a Gigabit Ethernet interface. Internally, the corresponding virtual B port
connects to an virtual E port which completes the end-to-end E port connectivity requirement.
Figure 24-12 FCIP Link Terminating in a B Port Mode
The B port feature in the IPS module allows remote B port SAN extenders to communicate directly with
a Cisco MDS 9000 Family switch, therefore eliminating the need for local bridge devices.
Configuring B Ports
When a FCIP peer is a SAN extender device that only supports Fibre Channel B ports, you need to enable
the B port mode for the FCIP link. When a B port is enabled, the E port functionality is also enabled and
they coexist. If the B port is disabled, the E port functionality remains enabled.
E Port Configurations
All configuration commands that apply to E ports, also apply to FCIP interfaces. The following features
are also available FCIP interfaces:
•
VSANs
–
FCIP interfaces can be a member of any VSAN.
–
Trunk mode
– Trunk mode can be configured.
–
