Define a bridge
auto vmbr-int allow-ovs vmbr-int iface vmbr-int inet manual ovs_type OVSBridge ovs_ports l2port
- auto is necessary to allow an automatic start (Ubuntu 16.04 using systemd)
- allow-ovs is the marker for an Openvswitch bridge. The bridge name follows, here vmbr-int
- iface is the well known /etc/network/interfaces identifier to start an interface configuration
- ovs_type defines the interface type for ovs. OVSBridge identifies an Openvswitch bridge
Define a L2 port (untagged)
allow-vmbr-int l2port iface l2port inet manual ovs_bridge vmbr-int ovs_type OVSPort ovs_options tag=444
- allow-[name of the bridge to attach the port] defines the name of the bridge, to which the port should be attached to. In our example this is vmbr-int. The name of the port follows (here l2port)
- iface is the well known /etc/network/interfaces identifier to start an interface configuration — set the config to manual
- ovs-bridge holds the name of the bridge to which the port should be attached to. In our example this is vmbr-int.
- ovs_type defines the interface type for ovs. OVSPort identifies an Openvswitch port not seen by the Linux Operating system
- ovs_options defines additional options for the port – here define an untagged port, which is member of Vlan 444. If this option is not set, a port may use all vlan tags on the interfaces, because all ports transport vlan tags by default.
Define a L3 interface
allow-vmbr-int l3port iface l3port inet static ovs_bridge vmbr-int ovs_type OVSIntPort ovs_options tag=444 address 192.168.1.254 netmask 255.255.255.0
- iface — set the mode to static — because an IP address is configured on this interface
- ovs_type — an L3 port must be defined as an internal port — must be set to OVSIntPort
- address and netmask are the well known parameters for IPV4 an address/netmask combination
Define a L2 port (tagged/trunking)
allow-vmbr-int l2taggedport iface l2taggedport inet manual ovs_bridge vmbr-int ovs_type OVSPort ovs_options trunks=2101,2102,2110,2120,2999,3000
- A trunking port does not require an additional definition. In the example above, we want to limit the vlans on the port. This requires a trunk definition using the ovs_options line.
Define a tagged LACP bond port
allow-vmbr-int bondpub iface bondpub inet manual ovs_bridge vmbr-int ovs_type OVSBond ovs_bonds eth4 eth5 ovs_options other_config:lacp-port-id=103 bond_fake_iface=true bond_mode=balance-slb lacp=active other_config:lacp-time=fast bond_updelay=2000 bond_downdelay=400 trunks=2101,2102,2110,2120,2999,3000
