# Network Usage

Networks are attached to interfaces on a compute server. The interfaces can be the physical ports themselves or bond interfaces that combine two physical ports into an aggregated pipe. Bond interfaces provide the benefits of aggregated bandwidth on a single interface and also high availability by providing port-level redundancy.

Once the decision is made on what kind of interfaces to use, networks can be chosen from the preconfigured list to attach to the network interfaces. This determines which VLANs are configured on which switch ports (or LAGs). As mentioned earlier, the primary VLAN is provisioned as an untagged VLAN, and the trunk VLANs are provisioned as tagged VLANs on the server ports.

The supported bond types are:

- Static Bond: This uses an L2+L3-based hash on the server OS and a static LAG on the switches.
- LACP Bond: This uses the LACP mode on the server OS and LACP LAG on the switches.
- Switch Independent Bond: This uses the balance-tlb mode on Linux servers and the switch-independent mode on Windows. The switch is configured as independent physical ports.
