1. Install Open vSwitch

apt update
apt install openvswitch-switch -y

2. Define LACP Bond

cat >> /etc/network/interfaces <<'EOF'
auto bond0
iface bond0 inet manual
        ovs_type OVSBond
        ovs_bridge vmbr0
        ovs_bonds eno1 eno2
        ovs_options bond_mode=balance-tcp lacp=active other_config:lacp-time=fast
EOF

3. Configrue Switch Side (Huawei Example)

interface Eth-Trunk10
 description to-pve-node1
 port link-type trunk
 undo port trunk allow-pass vlan 1
 port trunk allow-pass vlan 10 to 4094
 mode lacp

interface GigabitEthernet0/0/1
 description uplink-1
 eth-trunk 10

interface GigabitEthernet0/0/2
 description uplink-2
 eth-trunk 10

4. Create Management VLAN Interface

cat >> /etc/network/interfaces <<'EOF'
auto mgmt
iface mgmt inet static
        address 10.10.10.11/24
        gateway 10.10.10.1
        ovs_type OVSIntPort
        ovs_bridge vmbr0
        ovs_options tag=10
EOF

5. Define the OVS Bridge

cat >> /etc/network/interfaces <<'EOF'
auto vmbr0
iface vmbr0 inet manual
        ovs_type OVSBridge
        ovs_ports bond0 mgmt
EOF

6. Complete /etc/network/interfaces

# Loopback
auto lo
iface lo inet loopback

# Physical NICs
auto eno1
iface eno1 inet manual

auto eno2
iface eno2 inet manual

# Bond
auto bond0
iface bond0 inet manual
        ovs_type OVSBond
        ovs_bridge vmbr0
        ovs_bonds eno1 eno2
        ovs_options bond_mode=balance-tcp lacp=active other_config:lacp-time=fast

# Management VLAN
auto mgmt
iface mgmt inet static
        address 10.10.10.11/24
        gateway 10.10.10.1
        ovs_type OVSIntPort
        ovs_bridge vmbr0
        ovs_options tag=10

# Bridge
auto vmbr0
iface vmbr0 inet manual
        ovs_type OVSBridge
        ovs_ports bond0 mgmt
