STRANGE ERROR WITH WIFI AP ETH PORT

[LeLLa]

Hello,
i have a strange issue with the eht interface used for wifi (Zyxel AP Wifi 6)
The conf is like this

eth1 --> 192.168.10.0/24 - WIFI --> AP ZYXEL WIFI 6
eth2 --> 192.168.0.0/24 - LAN --> SWITCH HPE



I had no error since 1 month but today after enabling collision detection on the HPE i had issue on the other interface (eth1)
After loggin to the firewall i saw a bunch of errors on eth1 and errors on the DHCP for the subnet

The only fix was a full reboot
