Do I need to delete my interfaces before creating a LAGG group?
-
My current pfSense router has two Ethernet ports. One port was for the cable modem and the other went to a managed switch.
I'd now like to connect my cable modem to my switch (on a dedicated VLAN), and then create a fault-tolerant LAGG on the two ports on my router to my switch.
However, do I need to delete all my existing interfaces? I have a lot of reserved DHCP addresses, etc, that I'd rather not need to recreate.
Thanks!

I have zero networking knowledge, but this don't sound the slightest bit right. To plug your cablemodem into your switch sounds incorrect. Even with your proposed VLAN method.
Just wanted to save you the headache. You are creating problems for yourself.

Even if you could manage to migrate you interfaces how are you going to administer them? You really need 3 interfaces. You could use wifi(standing by for flak!!).

Seems like just from a latency viewpoint you are introducing 3 extra hops for every internet packet with your VLAN approach..

Plus I think that you basically would have your switch "Internet Facing" so any vulnerabilities there could be nasty. VLAN or Not.
I really wish a network professional would chime in as I am not trained. Maybe your VLAN method is hunky dory. It sounds risky to me. Did you find this method in a how-to or what?If its just for experimentation you may be able to get it working.
That second post from the forum was to show how messed up things can go. The official pfSense instructions look fine, but you will lose all your interface settings. Count on it your first couple of times. Especially if interface 'constrained'.

And what sense should this make?

If you want to start messing around with LAGG you'll probably just need to bit the bullet and get more interfaces.
Amazing how you start to chew through switch ports and interfaces when you start down this road. I just had to get a 48-port switch for my home/bench. Ran out at 24.
