Configuration Overview

Fibre Channel Port Configuration

By default, the configuration of the Fibre Channel ports is set to N_Port, forcing
the router to negotiate a fabric only mode.
Channel port speed must be manually set, such as for 1 Gb/s. If set incorrectly and the
router is plugged into a Loop or Fabric, the unit may receive framing errors, which can be
found in the trace logs, and the fiber link light will be off because of the incorrect Fibre
Channel link speed. For more information on manually setting the Fibre Channel port
speed, see Chapter 3,

Fibre Channel Switched Fabric Configuration

When connected to a Fibre Channel switch, the router is identified to the switch as
a unique device by the factory programmed World Wide Name (WWN).

Discovery Mode

This feature makes it easy to discover attached Fibre Channel and SCSI target
devices and automatically map them on the host side for the bus/port in question.
There are two discovery methods available:
Auto Discovery can be set to occur after reboot events (when the router reboots)
or link-up events (for instance, when cables are attached or a hub is rebooted).
Auto Discovery can be disabled by setting the router to Manual Discovery.
For more information on setting the Discovery Mode, see Chapter 3,

Host Device Configuration

A host system using a Fibre Channel Host Bus Adapter (HBA) will typically map
devices into the existing device-mapping scheme used by that operating system.
Refer to the HBA manual for the mapping table.
By default, the Fibre Channel port speed is set to 2 Gb/s. Changes to the Fibre
