Administration of Other Link Types

The separation between network configuration and network hardware configuration introduces the same flexibility to other types of link configurations. For example, virtual local area networks (VLANs), link aggregations, and IP tunnels can be assigned administratively-chosen names and then configured by referring to those names. Other related tasks, such as performing dynamic reconfiguration (DR) to replace hardware devices, are also easier to perform because no further network reconfiguration is required, provided that the network configuration was not deleted.

The following figure shows the interrelationship among devices, link types, and their corresponding interfaces.

Note - In the figure, the datalinks are named according to specific functions that they perform in the system, such as video0 or sales2. The figure intends to highlight the flexibility with which you can name the datalinks. However, using the default neutral names such as net0 as supplied by the OS is sufficient and preferable.

The figure also provides a sample of how administratively chosen names can be used in the network setup;

All of the link and interface configurations in this figure are independent of the configurations in the underlying hardware. For example, if the qfe card is replaced, the video0 interface configuration for video traffic remains and can later be applied to a replacement NIC.

The following figure shows a bridge configuration. Two interfaces, net0 and videoagg0, are configured as a bridge, bridge0. Packets that are received on one are forwarded to the other. After bridge configuration, both interfaces can still be used to configure VLANs and IP interfaces.
