Send SNMP Trap
Applies To: Opalis 6.3
The Send SNMP Trap object will raise an SNMP event that can be detected by a network systems manager application. By using an enterprise identifier of a known network device, you can send SNMP Traps on behalf of a network device in your system.
To configure SNMP version 3 security in the client, on the Options menu click SNMP.
Use the Send SNMP Trap to create events for Policies that need to be tracked using an SNMP monitoring product.
Configuring the Send SNMP Trap Object
To configure the Send SNMP Trap object you need to know the IP address of the device where you are sending your SNMP trap, the identifiers of the trap, the SNMP version you will use, and the address of the agent that you want to identify as the sender of the SNMP trap information.
To configure the Send SNMP Trap object
From the Objects pane, drag a Send SNMP Trap object to the active Policy.
Double-click the Send SNMP Trap object icon. The Properties dialog opens.
