SNMP ifIndex Persistent Command for FortiGate Firewall

Greetings to everyone,

I am experiencing an issue where the ifIndex values for interfaces on my FortiGate firewall change dynamically. This causes discrepancies in my SNMP monitoring setup, as it relies on static ifIndex values.

Is there any command or configuration setting to make ifIndex values persistent on a FortiGate firewall?

Thanks in advance for your support!
