Managing Networks

You manage a hypervisor's networks from the Networks tab of its detail page in the Gallium Console. For how bridges, the NAT network, and VLANs fit together, see the networking overview.

Bridges​

Bridges correspond to the physical adapters Gallium discovered on the server, so you cannot create or delete them. Select Edit on a bridge to change its Name or its MTU, which must be between 1500 and 9000. The built-in NAT network cannot be edited or deleted.

VLAN Networks​

VLAN networks are created as children of a bridge, letting one physical adapter carry several tagged networks that match the 802.1q trunk configuration on your switch.

  1. On the Networks tab, find the bridge that will carry the VLAN and select Add VLAN.
  2. Enter a Name for the network.
  3. Enter a VLAN ID between 2 and 4094. This must match the VLAN configuration on the switch port the bridge's adapter is connected to.
  4. Select Create.

The new VLAN appears nested beneath its parent bridge and becomes selectable when you attach a network adapter to a virtual machine. See network interfaces.

After creation only the name can be edited. The VLAN ID and parent bridge are fixed, so to change the ID, delete the VLAN and add a new one.
