z After the switches form a fabric, you can use the info-center switch-on command to enable the
information output for the switches to make the log, debugging and trap information of each switch
in the fabric synchronous. Each switch sends its own information to other switches in the fabric and
receives information sent by other switches at the same time to update the information on itself. In
this way, the switch ensures the synchronization of log, debugging and trap information in the
whole fabric.
z Be sure to set the correct IP address when using the info-center loghost command. A loopback IP
address will cause an error message prompting that this address is invalid.
