Enabling SNMP notifications for the MAC address
table
After you enable SNMP notifications for the MAC address table, the device will send SNMP
notifications to the SNMP module to notify the NMS of important events. You can set the notification
sending parameters in SNMP to determine the attributes of sending notifications.
After you disable SNMP notifications for the MAC address table, the device will only send log
messages to the information center module. You can set the output rules and destinations to
examine the log messages of the MAC address table module.
For more information about SNMP notifications and information center, see
