Web interface not accessible with VLAN tag?

[sofakng]

How do I configure Proxmox (Debian?) to allow a VLAN tag on my management interface?

For example, I have a dedicated port on my network switch for Proxmox web management. However, this port is tagged with a VLAN tag. However, when I enable tagging on the port it stops responding.

How can I fix this?

I'd like to have the following setup:

eth0 = management interface, DHCP assigned, VLAN 10, ProxMox web interface
eth1 + eth2 = bridged, used for VMs, needs to support VLAN tagging (VLAN 10, 30, etc)

Tag the port in Proxmox ?

or

which ever flavour tickles your fancy.

Thanks!

Can anybody verify my interfaces? It's working, but it seems like if I make a change on my physical switch (48-port EdgeSwitch Lite) that I need to reboot ProxMox which doesn't seem correct. I'm also using the built-in Linux bond/bridge instead of OVS but OVS does look interesting and perhaps a bit easier to understand...

Here is my goal:

bond0 - eth3 and eth0 using LACP. This is only used for ProxMox web interface (and lightweight FTP server I installed on ProxMox/Debian). This communicates on VLAN 10.

bond1 - eth1 and eth2 using LACP. This is used for VMs and uses several different VLAN IDs specified in the LXC configuration files.

Thanks for any information!
