Netgear switch dhcp
I have two Netgear switches (XS716T and XS728T) connected to a Juniper firewall. When I connect the laptops to the switches, sometimes I get the incorrect dhcp and default gateway. I called Juniper, and after 2 hours they said it's the switch causing the issue because I can see the switch making dhcp request.
How do I stop the Netgear switches from making dhcp decisions?

Check the switch and disable any DHCP snooping, DCHP static bindings, DHCP snooping persistent entries, ...

so far, I'm only seeing DHCP snooping, and disabled on both switches. I think I'm having the same issue, I'll double check tomorrow.
I don't have any static bindings etc.
I ran WireShark, and I can see the switches handling dhcp instead of the firewall for some reason.
Operating bunches of XS7xxT in core, backhaul, and device access with customers and here at home/office. All fully DHCP transparent, all DHCP is handled by the designated systems for the various VLANs (some on similar security appliances, some on Windows AD Servers) in a transparent way (with hundreds of systems/devices btw.).
Proabbly time for a factory reset and a manul reconfig from scratch?
Without more insight it's hard to help.
