switchBeacon

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.
