Configuring MAC Threshold Notification Traps

When you configure MAC threshold notification, an SNMP notification is generated and sent to the
network management system when a MAC address table (MAT) threshold limit is reached or exceeded.
To configure MAC address threshold notification, perform this task:
Command

set this string by using the snmp-server host

feature.
To disable this feature, use the
no address-table notification threshold global

percentage of the MAT utilization; valid values
are from 1 to 100 percent. Default is 50 percent.

•
between notifications; valid values are greater
than or equal to 120 seconds. Default is 120
seconds.
