LAGG (Link Aggregation)

[MR-NT]

using LAGG (Link Aggregation) gaining extra bandwidth, redundancy, or some combination faetures

Is that mean this feature can replace the a broadband bonding device infront of pfSense Box ?

i appreciate your recommendation

Probably not.

It depends exactly what that box is doing though. For example pfSense can do ML-PPP itself:
