Hi,
Until today I had the standard Linux bridge vmbr0 with eth2 as the only bridge port - that worked fine.
I now have a use case where I need an LACP 802.3ad bond between my main PVE host and my switch so I configured an active 802.3ad LAG port on the switch and added one of the spare 10GbE ports to it. I then created a Linux bond called bond0 and added the only 802.3ad member port to the bond and set an IP on it (for testing). bond0 is in LACP bond mode. That works fine i.e. I can ping the bond's IP, so I assume that means LACP 802.3ad is working. (Does it?)
So then I removed the IPV4 address from bond0 and removed eth2 from vmbr0 and added bond0 as the only bridge port and restarted networking but I immediately lost my connection to the PVE host. I checked the /etc/network/interfaces configuration and can see bridge-ports is set to bond0 so the configuration did save, but it doesn't work. I reverted back to eth2 as the only bridge port and the host came back online.
I somewhat confirmed this "looks" right based on a comment from Dunuin here: https://forum.proxmox.com/threads/proxmox-bonding-used-bond-for-containers-vms.105485/
I then created a test bridge called vmbr1 and added bond0 to it. That saved OK and I still have a connection. BUT, VMs and LXCs can't get a DHCP IP so something's not right.
What am I doing wrong? The desired end case is a 20Gbps bond but I'm happy with 10Gbps until I confirm this all works.
I'm sure I'm doing something basic wrong but I can't figure out what it is. Thanks in advance for any help.
Here's my current /etc/network/interfaces:
(eth1 is connected to the physical switch port that is also the only LAG port member)
The only line that changed when I reconfigured vmbr0 to contain bond0 and not eth2 was this line:
