switchBeacon 2 switchBeacon Sets switch beaconing mode on or off. SYNOPSIS switchbeacon [mode] DESCRIPTION NOTES OPERANDS EXAMPLES Use this command to enable or disable switch beaconing mode. Switch beaconing can be used to locate a failing unit. 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. 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 (such as portLoopbackTest) 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. The switchBeacon 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. For example, if you enabled beaconing on the logical switch (1) and you want to enable beaconing on the entire chassis, you must first disable switch beaconing with the switchBeacon command before you can use the chassisBeacon command to enable beaconing on the entire chassis. Likewise, 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. To determine whether or not beaconing is enabled or disabled on the switch or chassis, use the switchBeacon or chassisBeacon command without operands. A value of 0 indicates that the command is disabled, a value of 1 indicates that the command is enabled. Issue the portBeacon --show command to display beaconing for a specific port. The switchShow command displays the status of the switchBeacon command only. The switchBeacon command is not supported on the Brocade FCOE10-24 blade. 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 operand: mode Specify 1 to enable beaconing mode or 0 to disable beaconing mode. This operand is optional. If no operand is specified, the current value is displayed. To turn beaconing mode on and to verify the configuration: switch:admin> switchbeacon 1 switch:admin> switchbeacon value = 1 Fabric OS Command Reference 53-1002746-01 1001
