There are many synonims, but the so called static bonding doesn't require a switch that supports the dynamic LACP protocol. It will simply be bunch of ports acting as one.

I agree that if this is for bandwith, bonding is the way to do it. Otherwise it makes no sense having IPs from the same subnet on two ports.

PS EDIT: To complement my post, it would still require a switch that support static LA but even ancient switches support this, even the ones not supporting LACP.
