Hi.
I am just a beginner in cumulus so just doing some hands-on but i m facing some issue with this error message. Can anyone tell me the reason of this error message when the config is correct on both the switches
"An illegal loopback as occurred on adapter swp1"
"check the configuration and verify that all the adapters are connected on 802.3ad complaint switch port.

I am doing it on Cumulus VX

Hi, what does your config looks like? Are you bonding over the correct interfaces?

Same MAC address coming back in causes this message. That can happen in a back-to-back MLAG scenario where the same Sys-MAC is used but it can also happen in the scenario described above or if the virtual connections have accidentally created a loopback.
