portBeacon

Sets port beaconing mode.

Synopsis chassisbeacon [mode] [slot]port

chassisbeacon --help

Description Use this command to enable or disable beaconing on a specified 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.

When beaconing mode is enabled on a port, the port LED flashes amber and green for 2.5 seconds

each in an alternating pattern. The beaconing mode continues until you turn it off. Beaconing mode

is useful if you are trying to locate a specific port.

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.
