This section describes interface types, physical interface numbering rules, interface views and prompts to help you easily operate and configure the device.
Interfaces of a device are used to exchange data and interact with other network devices. Interfaces are classified into physical interface, and logical interfaces, as shown in Table 1.

Physical Interfaces |
Layer-3 Ethernet interface |
Works at the network layer to process Layer-3 packets with an IPv4 or IPv6 address specified and supports routing functions. NOTE:
An Ethernet interface works at Layer-3 by default. To use the Layer-3 Ethernet interface as a Layer-2 interface, switch the Ethernet interface to Layer-2 mode. |
Configured by following the procedure in Configuring a Layer-3 Ethernet Interface |
Configured by following the procedure in Configuring a Layer-3 Ethernet Interface |
Layer-2 Ethernet interface |
Works at the data link layer and processes Layer-2 packets, implementing rapid Layer-2 forwarding. |
Configured by following the procedure in Configuring a Layer-2 Ethernet Interface |
Configured by following the procedure in Configuring a Layer-2 Ethernet Interface |
|
Logic Interfaces |
Eth-Trunk Interface |
Multiple Layer-2 or Layer-3 Ethernet interfaces can be bundled into an Eth-Trunk interface. The Eth-Trunk interface provides all functions that Ethernet interfaces have and higher bandwidth and reliability, compared with a single Ethernet interface. |
Configured by following the procedure in Configuring an Eth-Trunk Interface |
Configured by following the procedure in Configuring an Eth-Trunk Interface |
Sub-interface |
Sub-interfaces are virtual interfaces configured on an interface for communicating with remote ends. |
Configured by following the procedure in Configuring a Layer-3 Ethernet Subinterface and Configuring a Layer-2 Ethernet Subinterface |
Configured by following the procedure in Configuring a Layer-3 Ethernet Subinterface and Configuring a Layer-2 Ethernet Subinterface |
|
VLAN Interface |
VLAN interfaces are Layer-3 logical interfaces. IP addresses can be configured for the VLAN interfaces for inter-VLAN communication. |
Configured by following the procedure in Configuring a VLAN Interface |
Configured by following the procedure in Configuring a VLAN Interface |
|
Loopback Interface |
Loopback interfaces remain Up after they are created and can be configured with 32-bit subnet masks. |
Configured by following the procedure in Configuring a Loopback Interface |
Configured by following the procedure in Configuring a Loopback Interface |
|
Dialer Interface |
Dialer Interfaces apply to PPPoE. A PPPoE session can be created using a dialer interface. |
- |
Configured by following the procedure in Configuring a Dialer Interface |
|
Tunnel Interface |
Tunnel interfaces are logical interfaces that have Layer-3 features. Devices on the two ends of a tunnel use the tunnel interfaces to send, receive, identify, and process tunnel packets. Tunnel interfaces apply to GRE and tunnel features for IPv6 transition. |
Tunnel interfaces are automatically created and configured when you configure GRE on the web management page. Configured by following the procedure in Configuring GRE |
Configured by following the procedure in Configuring a Tunnel Interface |
|
Virtual-if Interface |
Virtual-if interface: The interface is used by the virtual system to communicate with another virtual system for packet forwarding. A Virtual-if interface is a logical interface, each of which corresponds to one virtual system.
NOTE:
For details on virtual systems, see Virtual System. |
Configured by following the procedure in Deploying a Virtual System Using the Web UI |
Configured by following the procedure in Deploying a Virtual System Using the CLI |
|
Virtual-Template Interface |
Virtual-Template interfaces apply to L2TP for PPP negotiation and tunnel encapsulation. |
Virtual-Template interfaces are automatically created and configured when you configure L2TP on the web management page. Configured by following the procedure in Configuring the LNS |
Configured by following the procedure in Configuring a Virtual Template Interface |
|
BDIF Interface |
BDIF interfaces are Layer-3 logical interfaces. IP addresses can be configured for the BDIF interfaces for inter-VXLAN communication. |
Configured by following the procedure in Configuring VXLAN Interfaces |
Configured by following the procedure in Configuring BDIF Interfaces (VXLAN Interfaces) |
