Usg flex 500 loop

Darkn3ss

Hi, I'm having trouble configuring multi vlan on lan groups. As you can see from the image I have set everything on different vlans, but as soon as I connect 2 LAN cables (p4 and p5) on port 1 and 2 of the switch, everything goes in a loop. How can I solve it?

Firewall USG FLEX 500

SWITCH GS1920-24HP

Thanks

You may have a check P1 & P2 port setting on switch, and have a try to disable "Management control" function from these ports and make sure if it helps.
