Description This article describes the reasons behind the 'RADVD unloaded interface' log.
Scope FortiGate, system logs.
Solution

In some scenarios, the following log output is continuously generated in FortiGate:


date=2026-02-23 time=00:50:43 eventtime=1729730993598460793 tz="+0000" logid="0100020058" type="event" subtype="system" level="information" vd="root" logdesc="RADVD unloaded interface" msg="Interface port22 reloaded!"

 

The condition that triggers this log:
When system rebooting, interfaces will get a linklocal address from their own MAC address. After HA established, they will have another linklocal address to communicate with HA. At this point, any configuration change will trigger linklocal compare: each time the configuration changes, the code unloads and reloads the interface.

 

This issue does not impact the traffic: it is only a debug message.
