372 CHAPTER 12: USING SYSTEM MANAGEMENT COMMANDS
After the forming of a Fabric by switches which support the XRN, the log,
debugging and trap information among the switches is synchronous. The
synchronization process is as follows: each switch sends its own information to
other switches in the Fabric and meantime receives the information from others,
and then the switch updates the local information to ensure the information
coincidence within the Fabric.
The switch provides command line to turn on/off the synchronization switch in
every switch. If the synchronization switch of a switch is turned off, it does not
send information to other switches but still receives information from others.
Example
To turn on the trapping information synchronization switch of the unit 2, enter the
following:
<SW4500>system-view
System View: return to User View with Ctrl+Z.
[SW4500]info-center switch-on 2 trapping
[SW4500]
info-center timestamp Syntax
info-center timestamp { log | trap | debugging } { boot | date | none
}
undo info-center timestamp { log | trap | debugging }
View

Parameter
log: Log information.
trap: Trap information.
debugging: Debugging information.
boot: Time elapsing after system starts. Format: xxxxxx.yyyyyy, xxxxxx is the high
