switchBeacon

Sets switch beaconing mode on or off.

Synopsis

switchbeacon [mode]

Description

Use this command to enable or disable switch beaconing mode. Switch beaconing can be used to
locate a failing unit.

When beaconing mode is turned on, the port LEDs flash amber, left to right and right to left, from
port 0 to the highest port number and back to port 0. The beaconing mode continues until you turn
it off.

The beaconing LED pattern continues until you turn it off. Beaconing mode takes over the port
LEDs. Other commands are still executable and functional. The normal flashing LED pattern
(associated with an active, faulty or disabled port for example) is suppressed and only the
beaconing pattern is shown. However, if diagnostic frame-based tests (such as portLoopbackTest)
are executed, two patterns are interleaved. The diagnostic test flickers the LEDs green and the
beaconing mode runs the LEDs amber at the same time.

Use the switchShow command to display the status of beaconing.

Note

The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command
Availability" for details.
