Important SNMP traps

Link Down and Link Up traps

This trap is sent when a FortiGate port either goes down or is brought up.

For example, the following traps are generated when the state of port34 is set to down using set status down, and then brought up using set status up:

NET-SNMP version 5.7.3 2019-01-31 14:11:48 10.1.100.1(via UDP: [10.1.100.1]:162->[10.1.100.11]:162) TRAP, SNMP v1, community REGR-SYS SNMPv2-MIB::snmpTraps Link Down Trap (0) Uptime: 0:14:44.95 IF-MIB::ifIndex.42 = INTEGER: 42 IF-MIB::ifAdminStatus.42 = INTEGER: down(2) IF-MIB::ifOperStatus.42 = INTEGER: down(2) FORTINET-CORE-MIB::fnSysSerial.0 = STRING: FG140P3G15800330 SNMPv2-MIB::sysName.0 = STRING: FortiGate-140D-POE

fgFmTrapIfChange trap

This trap is sent when any changes are detected on the interface. The change can be very simple, such as giving an IPV4 address.

For example, the user has given the IP address of 1.2.3.4/24 to port 1 and the EMS Manager has detected the following trap:

DISMAN-EXPRESSION-MIB::sysUpTimeInstance = Timeticks: (7975058) 22:09:10.58 SNMPv2-MIB::snmpTrapOID.0 = OID: FORTINET-FORTIGATE-MIB::fgFmTrapIfChange FORTINET-CORE-MIB::fnSysSerial.0 = STRING: FG140P3G15800330 IF-MIB::ifName.45 = STRING: port1 FORTINET-FORTIGATE-MIB::fgManIfIp.0 = IpAddress: 1.2.3.4 FORTINET-FORTIGATE-MIB::fgManIfMask.0 = IpAddress: 255.255.255.0 FORTINET-FORTIGATE-MIB::fgManIfIp6.0 = STRING: 0:0:0:0:0:0:0:0 

entConfigChange trap

The change to the interface in the previous example has also triggered the ConfChange Trap which is sent along with the fgFmTrapIfChange trap:

2018-11-15 09:30:23 FGT_A [UDP: [172.16.200.1]:162->[172.16.200.55]:162]: DISMAN-EXPRESSION-MIB::sysUpTimeInstance = Timeticks: (8035097) 22:19:10.97 SNMPv2-MIB::snmpTrapOID.0 = OID: ENTITY-MIB::entConfigChange 

fgTrapDeviceNew trap

This trap is triggered when a new device, like a FortiSwitch, is connected to the FortiGate.

For example, the following scenario has given the device a new trap for adding FortiAP on a PoE interface a FortiGate 140D-POE. The trap has important information about the device name, device MAC address, and when it was last seen.

fgTrapAvOversize trap

The fgTrapAvOversize trap is generated when the antivirus scanner detects an oversized file:
