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.

NOTES 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.
