Introduction to Interfaces

An interface is an important part of the Eudemon. It can exchange data and interact with other devices in the network.

Interfaces can be grouped into two types:

• Physical interface
• Logical interface

A physical interface exists physically and supported by physical parts, including:

• Local Area Network (LAN) interface

The LAN interface is mainly the Ethernet interface, by which the Eudemon exchanges data with the net device in local network.

• Wide Area Network (WAN) interface

The WAN interface is mainly the AUX interface and the E1/T1 interface, by which the Eudemon exchanges data with devices of external networks through WAN interfaces.

A logical interface is the interface that has not a physical existence. And at the same time, you need to create the following interfaces by configuring:

1. Sub-interface
2. Logical tunnel interface
3. Virtual template interface
4. Loopback interface
5. Null interface
