switchBeacon

Set switch beaconing mode on or off.

Synopsis switchBeacon 0|1

Availability admin

Description Use this command to set the switch beaconing mode on (if the operand is 1) or off (if the operand is

0).

When beaconing mode is turned on, the port LEDs flash amber in a running pattern from port 0 to

port 15, and then back again. The user sees a running pattern in amber LEDs, from left to right and

right to left. The pattern continues until turned off by the user.

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.
