Notifications are the messages sent by the agent to the manager on any event happening on the agent side. The SNMPv3 agent requires a mechanism for identifying the management targets to which notifications should be sent to perform authentication. SNMPv3 framework recommends the implementation of the SNMP-TARGET-MIB to do this operation.
If the agent is only SNMPv3 compliant, the implementation of the SNMP-TARGET-MIB is recommended. In case of multi-lingual agents where the agent wants to send notification to v1/v2c/v3 managers, the implementation of SNMP-NOTIFICATION-MIB is recommended. The SNMP-NOTIFICATION-MIB module contains objects for the remote configuration of the parameters used by an SNMP entity for the generation of notifications.
The SNMPv3 agent which has implemented the SNMP-NOTIFICATION-MIB sends the notification messages to the managers, irrespective of their versions. The various tables defined in the NOTIFICATION-MIB performs this functionality.
Remote Configuration
The notification table information in the agent can be configured by the SNMPv3 manager. Following are the steps to configure the agent from the manger.
Load the notification MIB, which contains all the tables to configure the community details.
Add an entry from the manager to the various notification tables of the notification MIB. This can be done by any of the following options.
Send SET requests for adding entries to the table.
Perform a multi variable set.
Using the SNMP TablePanel of the MibBrowser.
This is similar to adding a row to a table as explained in the Table Handling in Applications section.
