command.

Syntax Description This command has no arguments or keywords.

Defaults None.

Command Modes Administrator.

Command History

Usage Guidelines Use this command to change all FC interfaces to diagnostic mode prior to performing internal or external

loopback testing on individual FC interfaces.

• Use the fcswitch enable command to reenable all FC interfaces. An FC interface must be enabled

to run online loopback tests or to allow access to storage targets.

• Use the no fcswitch enable command to disable all FC interfaces. When you are ready to allow

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

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

Examples The following example sets all FC interfaces into a diagnostic state and then performs an internal

loopback test on the FC interface named fc6:

[SN5428-2A]# fcswitch diag

[SN5428-2A]# interface fc6 loopback internal
