Interface Type

Interface Type

Interfaces of a device are used to exchange data and interact with other network devices. Interfaces are classified into physical interface and logical interfaces.

  • Physical interfaces

    A device provides physical interfaces. Physical interfaces are categorized as management interfaces and service interfaces.

    • Management interfaces

      Management interfaces are used to log in to devices. Users can use management interfaces to configure and manage devices. Management interfaces do not transmit service data.

      NOTE:

      This document provides only configuration of service and logical interfaces. For the configuration of management interfaces, see the Huawei AR100&AR120&AR150&AR160&AR200&AR1200&AR2200&AR3200&AR3600 Series Enterprise Routers Configuration Guide -- Basic Configurations.

      Table 1-1 describes the management interfaces.

      Table 1-1  Description of management interfaces

      Interface

      Description

      Application

      Console interface

      A data connection equipment (DCE) interface that complies with the EIA/TIA-232 standard.

      The console interface is connected to the COM serial interface of a configuration terminal to set up an on-site configuration environment.

      mini USB interface

      Complies with the USB 1.0 standard.

      The mini USB interface is connected to the USB interface of a PC through a mini USB cable to set up an on-site configuration environment.

      MEth interface

      Complies with the 10/100BASE-TX standard.

      NOTE:

      Only the AR3670 supports the MEth interface.

      The MEth interface can be connected to the network interface of the configuration terminal or network management workstation, setting up on-site or remote configuration environments.

      NOTE:
      At any time, only one of the console interface and mini USB interface of a router can be used as the serial interface. By default, the console interface is used as the serial interface of the router.
    • Service interfaces

      Service interfaces transmit services and are classified into the following types:
      • LAN-side interface: used by routers to exchange data with network devices on LANs.
      • WAN-side interface: used by routers to exchange data with devices on external networks.

      Table 1-2 describes the service interfaces that the router supports.

      Table 1-2  Description of service interfaces

      Synchronous/Asynchronous serial (SA) interface An SA interface can work in synchronous mode as a synchronous serial interface or in asynchronous mode as an asynchronous serial interface. Link layer protocols such as PPP and FR can be configured on synchronous serial interfaces. Parameters such as the stop bit and data bit can be set on asynchronous serial interfaces.
      Async interface An async interface is used as a synchronous serial interface. The link layer protocol is PPP when async interfaces work in protocol mode. Parameters such as the stop bit and data bit can be set on asynchronous serial interfaces.

It can be assigned an IP address, processes Layer 3 protocol packets, has the same logical interfaces as a synchronous serial interface, works in different modes, and supports Point-to-Point (PPP), Frame Relay (FR), and Integrated Services Digital Network (ISDN).
      E1-F/T1-F interface An E1-F/T1-F interface is an E1/T1 interface working in fractional channelized mode. It is a simplified CE1/PRI or CT1/PRI interface. To reduce costs, E1-F/T1-F interfaces can be used in E1/T1 access scenario.
