FortiGate traps
The FortiGate agent can send traps to up to three SNMP trap receivers on your
network that are configured to receive traps from the FortiGate unit. For these SNMP
managers to receive traps, you must load and compile the Fortinet trap MIB onto the
SNMP manager.

Agent Up An administrator enables the SNMP agent. This trap is also sent
when the agent starts during system startup.
