Enabling SNMP notifications for the MAC address

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.
