Hello Lovely internet land.

I'm currently configuring:

Dell R510, Ubuntu 18.04 with a Mellanox ConnectX-2 (2x SFP+)
|| (SFP+)
LB8
|| (SFP+)
LB4m ---[Cat5e]--- WiFi AP ->) (<- Laptop
| (Cat5e)
Router

I have my Internet coming into a port on a LB4m which goes into a Bonded Pair of SFP+ which go into ports 1&2 of the LB8, works perfectly. Can ping and everything through the internet great.

When I enable LACP and plug both SFP+ cables in the connection fails, unable to ping the internet from the server or server from my laptop. When I unplug either of the SFP+ cables from either end. The link comes back up and can ping the set IP address and access the internet.

Can anyone see an issue with my setup? This is my first time setting up a LAG with Netplan
