[SOLVED] Management network on LACP

[Rizki Rivai]

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 ?

Hi,

what is the question?
The cluster network is not necessarily the management network.
Corosyc can get a problem with LACP.
The recommendation for the cluster network is a dedicated NEtwork.
A VLAN segment is not a dedicated network.

Sorry my question wasnt clear. On normal proxmox instalation management network is same with management network.

Your answer already clarify this. Now i need to find documentation on how to move cluster network to dedicated network with minimal downtime. Thank you very much.
