Creating VLAN Adapters
Managing Parallels Server Bare Metal Network
Parallels Server Bare Metal allows you to create new VLAN adapters on the Parallels server. You
can use these adapters later on to connect your virtual machines and Containers to any of the
available Virtual Networks (for more information on Virtual Networks, see Managing Virtual
Networks (p. 175)). VLAN adapters can be made using the vznetcfg vlan add command. To
create a new VLAN adapter, you need to specify two parameters.
• VLAN ID—an arbitrary integer number which will uniquely identify the virtual LAN among other
VLANs on the server.
• Physical network adapter on the server to which the VLAN is to be bound.
For example, you can execute the following command to make a new VLAN adapter, associate it
with a VLAN having the ID of 5 (i.e. with VLAN 5), and attach the VLAN adapter to the eth0
physical adapter on the server:
# vznetcfg vlan add eth0 5
To check that the VLAN adapter has been successfully created, execute the following command:
# vznetcfg if list
Name Type Network ID Addresses
eth0 nic 192.168.0.150/22,dhcp
eth0.5 vlan
...
VLAN adapters can be easily identified by the vlan designation shown in the Type column of the
command output. As you can see, only one VLAN adapter currently exists on the server. It is
assigned the name of eth0.5. This name is generated automatically on the basis of the specified
VLAN ID and the name of the physical adapter to which the VLAN adapter is tied.
At any time, you can delete the eth0.5 VLAN adapter and thus destroy VLAN 5 by issuing the
following command:
# vznetcfg vlan del eth0.5
Networking Modes in Parallels Server Bare Metal
In Parallels Server Bare Metal, any virtual machine and Container can operate in one of the two
networking modes:
• host-routed
• virtual network
Detailed information on these modes is given in the following sections.
