chassisBeacon

Sets chassis beaconing mode.

Synopsis chassisbeacon [mode]

Description Use this command to enable or disable beaconing on a chassis. Chassis beaconing can be used to

locate a failing port.

When beaconing mode is turned on, the port LEDs flash green at various rates across the chassis.

The beaconing continues until you turn it off.

Beaconing mode takes over the port LEDs. The normal flashing LED pattern associated with an

active, faulty, or disabled port is suppressed, and only the beaconing pattern is shown. Other

commands are still executable and functional. However, if diagnostic frame-based tests such as

portLoopbackTest are executed, the diagnostic LED pattern is interleaved with the beaconing

pattern.

Note 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.

Operands This command has the following operand:

mode Specify 1 to enable chassis beaconing mode or 0 to disable beaconing mode.

This operand is optional. If no operand is specified, the current value is

displayed.

Examples To turn chassis beaconing mode on:

switch:admin> chassisbeacon 1

Chassis beacon success 1

To turn beaconing mode off:

switch:admin> chassisbeacon 0

Chassis beacon success 0
