The IPS module and MPS-14/2 module support 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 a virtual E port that completes the end-to-end E port
connectivity requirement (see

The B port feature in the IPS module and MPS-14/2 module allows remote B port SAN extenders to
communicate directly with a Cisco MDS 9000 Family switch, eliminating the need for local bridge
devices.
Configuring B Ports
When an 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.
To enable B port mode using Fabric Manager, follow these steps:
Step 1 Choose ISLs > FCIP from the Physical Attributes pane.
You see the FCIP profiles and links in the Information pane.
From Device manager, choose IP > FCIP. You see the FCIP dialog box.
Click the Tunnels tab.
Step 2
You see the FCIP link information.
Click the Create Row icon in Fabric Manager or the Create button in Device Manager.
