Question about LAGG
-
Hey all, Ive tried to find a definitive answer on this, but I cant, and I dont have the equipment to lab this myself at the moment. Basically Im just wondering how pfSense handles LACP with two switches. If I have two switches, and want to LACP two NICs from each switch to a pfSense, do I LAGG 4 interfaces on the pfSense, or create two separate LAGG with 2 NICs in each. Lets assume the LAN is flat. Picture for reference:

A or B?

@bigups43 Are the two switches stackable ?
-
@nogbadthebad the two switches that I HOPEFULLY will be using are Aruba 2930f's. It looks like they CAN be stacked with VSF, but lets assume they cant be.
Cheers!

@bigups43 If you can get VSF working you should be able to have 1 LAGG across both switches.
If you can’t you’ll only be able to create a LAGG between one of the switches and pfSense.
-
@nogbadthebad OK, that makes sense. And if I cant get VSF working, how is that handled? Do you create two LAGG on the pfsense and address them both in the LAN?
-
@bigups43 Two or more interfaces in a single LAGG carrying all your VLANS to a LAGG on switch 1, then another LAGG on Switch 1 carrying all the VLANS to a LAGG on switch 2.
Never played with VSF as I’ve been using 2939m switches that stack from a dedicated stacking port otherwise I’ve been using VSX with the 8325 range.
-
@nogbadthebad If I wanted to use multiple switches with a pfsense, that werent stackable, would they still need to be daisy chained?
-
@bigups43 Yes.
The big advantage of stackable switches that that you have redundancy as you can run a single LAGG over multiple switches.
