LACP to Unifi

Hi all,

I've been running a Fortigate 61E in LAG mode (ie: static) on an Edgeswitch for some months now and it has worked well. I never managed to make it work in LACP.

Now I'm moving to a Unifi Switch, which only supports LACP, and ... they don't negotiate. Wether I use passive or active, they just won't talk to each other.

Any clue ?

Pretty sure it was a bug when LAGs were introduced to sub 100 models in 6.2.1. Static LAGs worked but it wouldn't do LACP.

The fix may not have made it into 6.4.x

According to bug fixes in 6.2.3 they fixed:

Aggregate link does not work for LACP mode active for FG-60E internal ports but works for wan1 and wan2 combination.

What firmware are you on? I remember there was a bug when they introduced LAGs on the lower models that LACP didn't work properly. Pretty sure it was fixed in 6.2.3, but I haven't tested it.
