Description: Trap is sent to managing FortiManager if an interface changes IP

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' FORTINET-300-MIB::fnFMTrapIfChange
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.12356.0.100

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:

zoo11-linux.zoo [UDP: [192.168.30.111]:59958->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (512440374) 59 days, 7:26:43.74
