switchBeacon
Sets switch beaconing mode on or off.
Synopsis switchbeacon [mode]
Description 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.
Use the switchShow command to display the status of beaconing.
Note The execution of this command is subject to Admin Domain restrictions that may be in place. Refer
to chapter 1, "Understanding Admin Domain Restrictions" and Appendix A, "Command Availability"
for details.
