Hello list,


I have a firewall with 2x Intel pro dual port cards.

On Intel A , port 1 goes to switch 1, port 2 goes to switch 2
On Intel B , port 1 goes to switch 1, port 2 goes to switch 2


I have created the following 2 lagg devices using LACP:

lagg0 = A1 + B1
lagg1 = A2 + B2

This works fine.


Now, what I had in mind was creating a lagg2 device using lagg0 and
lagg1 with failover.

That would provide redundancy in case of a switch failure.

ifconfig won't let me though:

# ifconfig lagg2 laggproto failover laggport lagg0 laggport lagg1
ifconfig: SIOCSLAGGPORT: Invalid argument



I suppose it's not possible to aggregate lagg interfaces ?

That would shatter my dreams :(
