Each switch sends its own information to other switches in the fabric andreceives information sent by other switches at the same time to update the information on itself. Inthis way, the switch ensures the synchronization of log, debugging and trap information in thewhole fabric.z Be sure to set the correct IP address when using the info-center loghost command. A loopback IPaddress will cause an error message prompting that this address is invalid.Setting to Output System Information to the Trap BufferFollow these steps to set to output system information to the trap buffer:To do… Use the command… RemarksEnter system view system-view —Enable the information center info-center enable OptionalEnabled by default.Enable system informationoutput to the trap bufferinfo-center trapbuffer[channel { channel-number |channel-name } | sizebuffersize]*OptionalBy default, the switch usesinformation channel 3 to outputtrap information to the trapbuffer, which can holds up to256 items by default.
