Hi,so as part of doing inter vlan routing, i have setup interface gigabitethernet 1/0/2 as a routed port and setup a default route using my routers interface ip address as the next hop for 0.0.0.0/0 ,etc.  My g1/0/2 interface keeps going down, almost daily. i have the routed port connected to the lan port on my pfsense router and somehow when i lose internet connection (which is normal for me...) the routed port seems to also go down and disable a bunch of stuff on vlan1000, its internal vlan, but also disables dhcp filter globally which is very annoying.

 

I get that dhcp filter is a layer 2 security and this switch is basically "emulating" a layer 3 interface *cuz its using internal vlans* by using the no switchport command and disabling some layer 2 protocols, but is there no way to not have it disable dhcp filter globally? its not even enabled on that port...

 

here are the logs that i get almost daily:
