Description: Fortinet legacy SNMP MIB for firmware version 3.00 products providing base system and interface management objects for older FortiGate devices.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is FORTINET-300-MIB?

FORTINET-300-MIB is a legacy Fortinet enterprise MIB written for FortiOS firmware version 3.00 on older FortiGate security appliances, providing baseline system and interface management objects. No sample objects were available in the source, but as a legacy "300-series" firmware MIB it would typically expose basic system identity/status objects (model, firmware version, uptime) and per-interface configuration/statistics, predating Fortinet's later, more detailed FORTINET-FORTIGATE-MIB. Administrators use such a MIB to monitor basic hardware/software status of an older FortiGate unit, such as system uptime, firmware version, and interface up/down state, though modern deployments would typically use the newer Fortinet MIB instead. There is no apparent dependency on other MIBs beyond standard IETF interface conventions it likely extends. It would be deployed on legacy FortiGate firewall/UTM appliances still running FortiOS 3.00 firmware in older network environments. Engineers can download the FORTINET-300-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in FORTINET-300-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • legacy FortiGate firewall/UTM appliance (FortiOS 3.00)

Monitoring Examples

Without concrete sample object names for this legacy module, a specific grounded example cannot be constructed; typically an admin would poll a system object for firmware version and uptime to confirm the appliance's basic health, alongside interface status objects to detect a down WAN or LAN interface on an older FortiGate unit.

What Can Be Monitored

  • system uptime
  • firmware version
  • interface up/down status

How to Use in IPNetwork Monitor

Example using fnHaStatsPktCount OID:

Select a Fortinet FortiGate firewall/UTM appliance (legacy FortiOS 3.00) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type fnHaStatsPktCount into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. Packets Counter of HA Cluster's unit. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
