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.

To turn on the trapping information synchronization switch of the unit 2, enter the 
following:

 Log information.

 Trap information.

 Debugging information.

 Time elapsing after system starts. Format: xxxxxx.yyyyyy, xxxxxx is the high 

32 bits of the elapsed time (in milliseconds) after system starts, and yyyyyy is the 
low 32 bits.

 Current system date and time. It shows as 

yyyy/mm/dd-hh:mm:ss

 in 

Chinese environment and 

mm/dd/yyyy-hh:mm:ss

 in Western language 

environment.

 No timestamp format.

Use the
