How to Preserve Advanced Bonding Options When Using Proxmox GUI

[rpierluigi]

Dear community,

I'm configuring a bonded interface on Proxmox VE using the active-backup mode and need to include some advanced ARP monitoring parameters for failover detection.

Here's the relevant part of my manual configuration in /etc/network/interfaces:

auto bond0
iface bond0 inet static
address 10.200.0.101/24
bond-slaves eno7 eno8
bond-mode active-backup
bond-primary eno7
bond-arp-interval 100
bond-arp-ip-target 10.200.0.201
bond-arp-validate filter

These last three parameters are essential for monitoring link state using ARP.
However, I understand that if I later make any changes via the Proxmox web GUI, the network configuration file might be regenerated and overwrite or discard these advanced options.

My question is:
How can I safely preserve these custom bonding parameters while still being able to manage other aspects of the network configuration via the GUI in the future?
Is there a recommended way to integrate these advanced bonding options into Proxmox in a persistent and GUI-compatible manner?

Any guidance would be greatly appreciated!
Best regards,

Pierluigi

Welcome to the Proxmox forum, rpierluigi!

The options should still be preserved even after changing them through the web interface. This shouldn't be necessary, but if you want to make sure that there is no interference, you can always create an extra configuration file in /etc/network/interfaces.d/, but this will make the network device invisible from the web interface list of network devices.
