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.

The IP address of an interface of a FortiGate unit changes. The trap
message includes the name of the interface, the new IP address of
the interface, and the serial number of the FortiGate unit. This trap
can be used to track interface IP address changes for interfaces
configured with dynamic IP addresses set using DHCP or PPPoE.
