portBeacon

Sets port beaconing mode.

Synopsis

portbeacon --enable [slot]port

portbeacon --disable [slot]port

portbeacon --show [slot]port

portbeacon --help

Description

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

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. Running switch beaconing or HBA- side (E2E) beaconing also overwrites the 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.
