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.

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 (like portLoopbackTest and

spinSilk) 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.

The execution of this command is subject to Admin Domain restrictions that may be in place.

Operands This command has the following operand:

mode Specify 1 to enable beacon mode or 0 to disable beacon mode. This operand

is optional.

If no operand is specified, the current value is displayed.

Examples To turn beaconing mode on:

switch:admin> switchbeacon 1

To turn beaconing mode off:

switch:admin> switchbeacon 0
