Each domain +VIF can then be configured with one or more VLAN IDs, one of which will be +the PVID. + +The example files create a bridge device called br0, with a physical inter= face=20 +called enp0s0. You will need to update this with your system's device name. + +Key points of the configuration are: + +1. In br0.netdev, VLANFiltering=3Don is set. This is required to ensure the + VLAN tags are handled correctly. If it is not set then the packets + from the VIF interfaces will not have the correct VLAN tags set. + +2. In br0.network, a system IPv4 address is configured that can be updated + according to your local network settings. + +3. In enp0s0.network, Bridge=3Dbr0 sets the bridge device to connect to. T= here + is also a [BridgeVLAN] section for each VLAN allowed on the external + interface. Note, if you want to create an internal VLAN private to the + host, do not include its VLAN ID in this file. + + +Domain configuration +-------------------- + +Add the vlan=3D keyword to the vif definition in the domain. The simplest +and most common example is a domain that wishes to connect to a single VLA= N: + +vif =3D [ 'mac=3Dxx:xx:xx:xx:xx:xx, bridge=3Dbr0, vlan=3D10' ] + +If you wish to configure a domain to route between two VLANs, you have two +options. Option 1 is to create multiple interfaces on different VLANs: + +vif =3D [ 'mac=3Dxx:xx:xx:xx:xx:xx, bridge=3Dbr0, vlan=3D10', + 'max=3Dxx:xx:xx:xx:xx:xx, bridge=3Dbr0, vlan=3D20' ] + +Alternatively, you can create single interface: + +vif =3D [ 'mac=3Dxx:xx:xx:xx:xx:xx, bridge=3Dbr0, vlan=3D10p/20' ] + +In the domain, you would, for example, use enX0 for VLAN 10 and enX0.20 fo= r=20 +VLAN 20. + + +Hints and tips +-------------- + +You can run the following commands on dom0 or a driver domain: + +1. To check if vlan_filtering is enabled: + # cat /sys/devices/virtual/net//bridge/vlan_filtering + +2. To check the bridge port VLAN assignments: + # bridge vlan + +3. To check the vlan setting in the xenstore (dom0 only): + # xenstore-ls -f | grep 'vlan =3D' + diff --git a/docs/misc/linux-bridge-vlan/br0.netdev b/docs/misc/linux-bridg= e-vlan/br0.netdev new file mode 100644 index 0000000000..ae1fe487c3 --- /dev/null +++ b/docs/misc/linux-bridge-vlan/br0.netdev @@ -0,0 +1,7 @@ +[NetDev] +Name=3Dbr0 +Kind=3Dbridge +MACAddress=3Dxx:xx:xx:xx:xx:xx + +[Bridge] +VLANFiltering=3Don diff --git a/docs/misc/linux-bridge-vlan/br0.network b/docs/misc/linux-brid= ge-vlan/br0.network new file mode 100644 index 0000000000..b56203b66a --- /dev/null +++ b/docs/misc/linux-bridge-vlan/br0.network @@ -0,0 +1,8 @@ +[Match] +Name=3Dbr0 + +[Network] +DNS=3D8.8.8.8 +#Domains=3Dexample.com +Address=3D10.1.1.10/24 +Gateway=3D10.1.1.1 diff --git a/docs/misc/linux-bridge-vlan/enp0s0.network b/docs/misc/linux-b= ridge-vlan/enp0s0.network new file mode 100644 index 0000000000..6ee3154dfc --- /dev/null +++ b/docs/misc/linux-bridge-vlan/enp0s0.network @@ -0,0 +1,16 @@ +[Match] +Name=3Denp0s0 + +[Network] +Bridge=3Dbr0 + +# If Jumbo frames are required +#[Link] +#MTUBytes=3D9000 + +[BridgeVLAN] +VLAN=3D10 + +[BridgeVLAN] +VLAN=3D20 + --=20 2.39.2
