Hello,
I have a pair of proxmox servers I'm attempting to configure to supply multiple VLANS over a pair of bonded interfaces to the hosted guest VMs.
If I give the sub interfaces an IP within the respective VLAN things work as expected. I don't want to number the interfaces but am unable the have them come up at system initialization time without an IP assigned. I have tried a few things within /etc/network/interfaces.
Is there a method to have these unnumbered interfaces come up via the interfaces file at boot time?
If I manually ifconfig up the sub-interface, it comes up and starts passing traffic. I'd like to have this happen automagically at boot time.
some info:
I tried using the variable and real name of the interface on both the sub and bond using documentation found both on proxmox and debian wikis. Not having any luck at all..
pre-up ifconfig $IFACE up
and
pre-up ifconfig bond0.140 up
as an example if I configure interfaces as below, they come up and are usable.
auto bond0.110
iface bond0.110 inet static
address 1.1.1.1
mask 255.255.255.255
All the other defined VLANs work as expected as well (if they also have an IP configured).
The managment network (10.101.8.x below) is not part of any of the defined VLANS.
Below is some information, if there is something you would like to see let me know and thanks in advance.
