SNMP MAC-notification trap support

The SNMP MAC-notification trap functionality allows an SNMPv3 trap to be sent to the SNMP manager when MAC addresses are added or deleted in the device. The SNMP manager or management software can then use these traps to define a security policy based on the requirement of the enterprise where the device is installed. With this functionality, management software can easily monitor the devices and build a security policy for enterprise networks.

Access ports can be manually configured to enable the MAC-notification feature. While enabling MAC-notification on a particular port, you can configure the interval at which the trap messages will be sent to management software, and the buffer size which maintains maximum trap events that can be maintained in the system. Ports enabled for MAC-notification will send SNMP traps to management software for various MAC address events such as addition, deletion, and MAC address movement.

The access devices in an enterprise network typically connect to the end host, and MAC-notification can be deployed on such devices on the access port only. An access port by definition is a port that connects to an end host and typically does not result in a network loop.
