switchBeacon

Sets switch beaconing mode on or off.

Synopsis switchbeacon [mode]

Description Use this command to enable or disable switch beaconing mode.

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. This

can be used to beckon to locate a failing unit, for example.

Beaconing mode affects only the port LEDs. Other commands are still executable and functional. The

normal flashing LED pattern (associated with an active, faulty, or disabled port) is suppressed and the

beaconing pattern is shown. However, if diagnostic frame-based tests (portLoopbackTest,

crossPortTest, and spinSilk) are executed, two patterns are interleaved. The diagnostic test flickers the

LEDs green and simultaneously the beaconing mode runs the LEDs amber.

Use the switchShow command to display the status of beaconing.
