Enable/Configure LLDP Notification Status/Type

By default, notification status is Disabled, and notification type is Mis-configuration. Notification type can be set to any of the following values:

Mis-configuration
Remote table change

Setting notification type to Mis-configuration enables LLDP to send notification to SNMP manager when mis-configuration is observed in the system. Setting notification type to remote table change enables LLDP to send notification to SNMP manager whenever remote table change occurs with the configured notification interval between successive notifications.
