Filtering Notifications

The Notification Filter functions in very much the same way as the VACM access control security does. First, in the snmpNotifyFilterTable, you define a profile name by including or excluding MIB objects which may be masked. Notifications associated with OIDs other than those specified are sent to the "bit bucket".

Next you use the snmpNotificationFilterProfileTable to associate the filter defined above with the snmpTargetParamsName which is a row in the snmpTargetParamsTable which supplies the parameters to the interface which will send the packet.

In this case the Notification is checked that all it’s elements fall in the view labeled "fp1" and if so, sends them using parameters labeled "p_1". Which is to say, use an SNMPv1 Message Processing Module using a SNMPv1 security Model. The Security Name of "initial" and the security Level of "noAuthNoPriv" are not necessary for the SNMPv1 Message Processing Module but are supplied here for those Modules that do require them.
