Send SNMP Trap
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,
use the
SNMP Options in the
Client.
How it is used
Use the Send SNMP Trap to create
events for Policies that need to be tracked using an SNMP
monitoring product.
Configuration
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.

Success if it was able to send the data, regardless of whether the
data were correct, or readable, or not.
