Bobnded/trunked interfaces with vmbr0 on untagged vlan

[kameleon]

Just as the title says I am looking to get my proxmox servers to reside on my untagged vlan which in my configuration is vlan 1. On my Xen servers I have done this with little to no issue. However when I attempt it in proxmox I am left with an unreachable network. I can put them on any other vlan and it works but cannot have it on vlan1. Am I missing something?

It just hit me that I can run it on vlan1 if it is not in a bonded interface. This may be due to running mode4 bonding. I am going to try mode6 and see what happens.

I encountered a similar situation with 802.3ad while back. It turned out to be a problem with how the LAGs were configured.

The other issue I am running into is on a mode4 bond it seems impossible to get my Dell DRAC cards to work. So I may be forced to go with mode6 afterall. If I read right mode6 will also allow full aggregate bandwidth on the bonded interfaces right? Like I have 2 gigabit interfaces it theoretically should do a maximum of 2gb/sec? Also, what is the LAGs you are referring to?

Does this look right for a single interface that is only a trunk? Two of my servers only have 2 NIC's and I need one to be the trunk'd interface while the other goes for SAN traffic only.

I found the way to make it work on an untagged vlan. At least it is working so far. Would someone look over this and make sure I did not mess up anything?
