This process starts out by defining a NotifyName which specifies the row in the snmpNotifyTable. This table will contain a Tag that will link this table to the "Target/TargetAddr" page where we will find the addresses of the destination management stations are stored. Additionally each row specifies the type of unsolicited packet associated with the destinations. I.e an "Inform" or a "Trap" packet.
Once the Notify Table is done the target parameters and addresses need to be specified. The parameters specify security and format information which are entered on the Target/TargetParams tab which supports the snmpTargetParams Table. First we give it a name for later reference. In the case below the simple names p_1 to p_3 are used.
The "Message Processing Model" defines the function which processes the parameters and has acceptable values of SNMPv1, SNMPv2c and SNMPv3. The security model and security levels have the same allowed values as always and a security name is the last element in the parameters.
The last step is to specify the targets to which the notifications will be sent, in the snmpTargetAddrTable as below. Once again a AddrName is given just to be a unique identifier of an address. The actual address has it’s own dialog box which guides you through entering an IP address and a port number. There is another dialogue box for "TagLists" which refers to the Tags defined in the first step. This allows you to send different formats of packets to the same destination as is demonstrated in the Address named "t2" below. Tag1 causes a trap to be sent while Tag2 causes an inform to be sent. The snmpTargetAddrParams name associates the address parameters from the Target Params tab to this row.
Now that we have specified the mechanisms that will be used for the unsolicited agent to management station communications it still remains to apply access control to the data which the Notification is attempting to send. This is done through "Filtering Notifications".
