Command History

Usage Guidelines Use this command to change the named FC interface to diagnostic mode prior to performing an internal

or external loopback test.

• Use the interface fc? enable command to reenable the FC interface. An FC interface must be

enabled to run an online loopback test, or to allow access to storage targets.

• Use the no interface fc? enable command to disable the FC interface. When you are ready to allow

access to the storage targets, you can enable all FC interfaces at once via the interface fc enable

command, or enable individual interfaces via the interface fc? enable command.

Examples The following example sets the FC interface fc6 into a diagnostic state and then performs an internal

loopback test:

[SN5428-2A]# interface fc6 diag

[SN5428-2A]# interface fc6 loopback internal

fc? The name of the FC interface to be placed into diagnostic mode. Valid

values are fc1 through fc8. When you type the interface fc? command, the

CLI lists the interfaces available. You cannot specify a nonexistent

interface.
