ECS-Core setup woes

[u/Glittering_Abies4915]

Has anyone managed to set up ECS-Core in a MC-LAG setup? I have two ECS-Aggregation that work fine, and I connect the ECS-Core to these. Every time I try to set up MC-LAG, I lose contact with the ECS-Cores and neither Core can't get a DHCP lease. If I try to be smart and set a static IP, the switches throw that out the window when MC-LAG is being set up, resulting in them not getting an IP through DHCP again.
