[PVE-User] Experimenting with bond on a non-LACP switch...

[Laurent Dumont]

It's not made very clear from the documentation. I assume there are good
technical reasons why the cluster traffic would be impacted.

Afaik, proxmox leverages corosync which can leverage multicast for the
cluster checks. I don't think it can be badly impacted by LACP but
something to keep in mind.

There is this old thread with a similar discussion :
