No SNMP Response from Fortigate Firewall

Published by at 12:47 pm under Fortinet

SNMP protocol is used to get a lot of metrics on most network hardware. I configured SNMP on the internal interface of a Fortigate 100D from Fortinet, and even though the enable checkbox is ticked, I am getting a timeout running cfgmaker (to configure MRTG) or snmpwalk. No SNMP response from the Fortigate. I do not get this issue on a Fortiwifi 60B.

It took me a while to figure it out but here is the trick. You have to configure the management interface and query that interface if you want to get SNMP information for all other interfaces. Management is a dedicated interface with a physical port just below the DMZ port.


Fortigate 100D physical ports


I looked up on Fortinet online documentation but this does not seem to be posted anywhere at the moment of this writing.

    I also have the issue of not being able to get any SNM answer from my fortigate 100D firewalls. forums I see lots of issues and work around. only I have not yet found the 1 to solve my issue.

    and I was from the beginning using the mgmt interface.

    my setup is an HA A-P setup with several VDOM’s

    anyone that can give tips would be great
