Hello, I have 500+ list of IP-MAC Reservation in my college environment. I cannot do the same by adding single at a time. it is very time consuming. Please help with your assistance to conclude my test quickly.
If you're adding these to the DHCP pool, the only way to add them will be via that dialogue box. If you're making that many reservations, I'd suggest using a DHCP relay or using a different DHCP server.

There is a feature request (FBX-9345) to allow a bulk import/export of this, but right now this will be the only way to accomplish that.
