We tested proxmox cluster of 3 server where management interface is not lacp bonded interface. Everything seems to work. But I read in wiki https://pve.proxmox.com/wiki/Network_Configuration that lacp not supported for management interface. Here whats the wiki wrote: ... If your switch support the LACP (IEEE 802.3ad) protocol then we recommend using the corresponding bonding mode (802.3ad). Otherwise you should generally use the active-backup mode. If you intend to run your cluster network on the bonding interfaces, then you have to use active-passive mode on the bonding interfaces, other modes are unsupported. The following bond configuration can be used as distributed/shared storage network. ... ... Anyone can clarify this ?
