2 portBeacon portBeacon Sets port beaconing mode. SYNOPSIS portbeacon --enable [slot/]port portbeacon --disable [slot/]port portbeacon --show [slot/]port portbeacon --help DESCRIPTION NOTES OPERANDS 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. The portBeacon command is one of three commands that control beaconing. Each command has a clearly defined scope of action: • The portBeacon command enables or disables beaconing on a specified port. • The switchBeacon command enables or disables beaconing on all ports in the current logical switch. • The chassisBeacon command to enables or disables beaconing on all ports in the chassis. The actions of the beaconing commands are independent and mutually exclusive. Existing portBeacon settings remain unaffected if you enable or disable beaconing on the switch or on the chassis. Failure to disable existing beaconing commands before using a different type of beaconing may cause the commands to interfere with each other in unexpected ways. Issue the portBeacon --show [slot/]port command to display beaconing for a specific port. The switchShow command displays the status of the switchBeacon command only. 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. This command has the following operands: slot For bladed systems only, specifies the slot number of the port group to display, followed by a slash (/). port Specifies the number of the port to be configured, relative to its slot for bladed systems. Use switchShow for a listing of valid ports. --enable Enables beaconing mode on the specified port. --disable Disables beaconing mode on the specified port. 622 Fabric OS Command Reference 53-1002746-01
