Interface Basics

Interface Basics

This section describes the interface types and numbering rules.

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

  • 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.

    The console interface is a management interface. Table 6-1 describes functions of the console interface.

    Table 6-1  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.

    NOTE:

    This chapter only describes physical and logical interfaces. For detailed configurations of management interfaces, see Basic Configuration Guide.

  • Physical interfaces

    Physical interfaces exist on interface cards and transmit service data

    Currently, physical interfaces on the device are Layer 2 Ethernet interfaces, which are connected to other network devices.

    Table 6-2 describes the physical interfaces supported by the device.

    Table 6-2  Description of physical interfaces
    Type Interface Description
    Layer 2 Ethernet interface FE interface A LAN-side FE interface works at the data link layer, provides a maximum of 100 Mbit/s transmission rate, processes Layer 2 protocol packets, and implements Layer 2 forwarding.
    GE interface A LAN-side GE interface works at the data link layer, provides a maximum of 1000 Mbit/s transmission rate, processes Layer 2 protocol packets, and implements Layer 2 forwarding.
    MultiGE interface A LAN-side MultiGE interface works at the data link layer, provides a maximum of 2500 Mbit/s transmission rate, processes Layer 2 protocol packets, and implements Layer 2 forwarding.
    10GE interface A LAN-side 10GE interface works at the data link layer, provides a maximum of 10000 Mbit/s transmission rate, processes Layer 2 protocol packets, and implements Layer 2 forwarding.
    NOTE:
    Currently, only the AD9431DN-24X supports 10GE interfaces.
    NOTE:
    • GE0/0/47 is a logical interface of a cloud AP. It is an internal communication interface and cannot be configured or modified by users.
    • Currently, only the AP7050DN-E supports MultiGE interfaces.
  • Logical interfaces

    Logical interfaces are manually configured interfaces and can be used to exchange data but do not exist physically.

    Table 6-3 describes the logical interfaces that the router supports.

    Table 6-3  Description of logical interfaces
    Interface Type Description
    Eth-Trunk interface An Eth-Trunk interface has Layer 2 and Layer 3 features and is formed by binding multiple Ethernet interfaces to provide more bandwidth and higher transmission reliability.
    VLANIF interface A VLANIF interface has Layer 3 features and enables VLANs to communicate after being assigned an IP address.
    Loopback interface A loopback interface is always Up and can be configured with a 32-bit subnet mask.
    Null interface A null interface is used to filter routes because any data packets received by the null interface are discarded.
  • Radio interfaces

    Radio interfaces are used to send or receive radio signals. They allow the device to provide wireless services. Table 6-4 describes the radio interfaces supported by the device.

    Table 6-4  Description of radio interfaces
    Interface Description
    2.4 GHz radio interface Based on IEEE 802.11 series standards, the 2.4 GHz radio interface uses the 2.4 GHz frequency band as a transmission medium to transmit wireless data.
    5 GHz radio interface Based on IEEE 802.11 series standards, the 5 GHz radio interface uses the 5 GHz frequency band as a transmission medium to transmit wireless data.
    NOTE:
    This section describes only the physical and logical interfaces of the device. For details about parameter configurations of the radio interfaces, see WLAN Service Configuration Guide (Common AP).

Interface Numbering Rules

  • Numbering Rules for Management Interfaces

    The following table lists the numbers of the management interfaces.

    Table 6-5  Management interface numbers

    Interface

    Number

    Console interface

    Console 0

  • Numbering Rules for Physical Interfaces

    The device's physical interfaces are numbered in the format slot ID/subcard ID/interface sequence number.
    • slot ID: indicates the slot where an interface is located. The value is 0.
    • subcard ID: indicates the ID of a subcard. The value is 0.
    • interface sequence number: indicates the sequence number of an interface on the device.
