Hi all, after a week of tests and errors I'm really going crazy to figure how to carry out my VLAN configuration, so I ask some help here.
This is my setup:
Proxmox 3.4.6 installed on a HP ProLiant DL380e; the server has 4 ethernet cards connected to a Cisco SG200-26 switch. I use eth0 only for management and I bonded together the other three cards in LAG mode for VM traffic. I need to use VLANs, so I configured the Cisco in this way:
LAG1: mode trunk, default VLAN untagged, VLAN 10 and 100 tagged member
switch port connected to my pc: mode trunk, default VLAN untagged, VLAN 10 and 100 tagged member.
Here's my /etc/network/interface:
I created 2 openvz machines (vm1 and vm2) for testing and this is the result:
- If I bind the vms on vmbr1 all works fine, I can ping them from my pc and they can ping each other;
- If I bind the vms on vmbr100 (or vmbr10) the vms can ping each other (so I assume the vlan interfaces are ok), but there's no traffic between them and my pc. The ping command says: Destination Host Unreachable
Can anyone tell me if the problem is in the Cisco switch configuration or in Proxmox?
I would greatly appreciate any hint, and sorry for my poor english
