How To Bond NICs In Proxmox That Support VLANs

Video Description

In this video, we show how to configure Proxmox to bond multiple network interfaces and support VLANs We show how to bind multiple interfaces together for more network throughput or network redundancy And cover how to re-configure the management interface so it's in your management VLAN We show how to configure a network switch to support VLAN tagging for Proxmox And how to add additional VLAN interfaces to Proxmox as well as how to configure virtual machines to support VLAN tagging Useful links: https://pve.proxmox.com/wiki/Network_Configuration#_vlan_802_1q ============================= SUPPORT THE CHANNEL Donate through Paypal: https://paypal.me/DavidMcKone Donate through Buy Me A Coffee: https://buymeacoffee.com/dmckone Become a monthly contributor on Patreon: https://www.patreon.com/dmckone Become a monthly contributor on YouTube: https://www.youtube.com/channel/UCNrXJt8B931zF7nDC_rM85A/join ============================== Steps taken 1) Configure Proxmox The default installation creates a dedicated management interface so we need to reconfigure Proxmox to bind the physical interfaces into a bond The quickest way is to edit the /etc/network/interfaces cp /etc/network/interfaces /etc/network/interfaces.bak nano /etc/network/interfaces To load balance traffic, the recommendation is to use LACP, for example auto lo iface lo inet loopback iface enp0s25 inet manual iface enp7s0 inet manual auto bond0 iface bond0 inet manual bond-slaves enp0s25 enp7s0 bond-miimon 100 bond-xmit-hash-policy layer2+3 bond-mode 802.3ad NOTE: If your switches support technology such as MLAG, you can connect the interfaces to different switches. Otherwise they need to be connected to the same switch To support network redundancy, an example would be auto lo iface lo inet loopback iface enp0s25 inet manual iface enp7s0 inet manual auto bond0 iface bond0 inet manual bond-slaves enp0s25 enp7s0 bond-miimon 100 bond-xmit-hash-policy layer2+3 bond-mode 802.3ad bond-mode active-backup bond-primary enp0s25 Either way, we need to reconfigure Proxmox with a management VLAN interface and make the Linux bridge VLAN aware. For example, to use VLAN 100 auto vmbr0.100 iface vmbr0.100 inet static address 192.168.100.10/24 gateway 192.168.100.254 auto vmbr0 iface vmbr0 inet manual bridge-ports bond0 bridge-stp off bridge-fd 0 bridge-vlan-aware yes bridge-vids 2-4092 Then we reboot Proxmox to make sure the changes are applied 2) Configure Switch Because Proxmox is now doing VLAN tagging but the network switch is not, we cannot access Proxmox remotely anymore so we need to reconfigure the switch ports We need to turn the port into a trunk port i.e. one which supports multiple VLANs and set the default, PVID or native VLAN to something unused Once this is done, the switch will send VLAN tagged traffic to Proxmox and our connection will be restored 3) Add VLAN interfaces to Proxmox Proxmox now has a VLAN aware bridge, so we can add VLAN interfaces to it for direct access to a storage VLAN for instance To do this select the computer in the left hand pane, navigate to System | Network and from the Create drop down menu select Linux VLAN Change the name to match the bridge and VLAN ID, for example for VLAN 200, we'd use vmbr0.200 Give the interface an IP address and mask, for example, 192.168.200.10/24 Then click Create On the switch, update the port connected to Proxmox to allow this VLAN Proxmox should now have access to other computers on your network in this VLAN 4) Assign VMs to VLANs Because Proxmox and the switch are using VLAN tagging, virtual machines will need to support VLANs For existing virtual machines, select the VM in the left hand pane then select Hardware Click on the Network Device and click Edit In the VLAN Tag field, enter the VLAN ID then click OK On the switch, update the port connected to Proxmox to allow this VLAN Repeat this for any other interfaces the VM has For new VMs, add the VLAN tag as part of the installation process Credits: LoveLife | Instrumental Prod.
