Logical Interface

Logical Interface

Context

The web platform supports the configuration of logical interfaces including loopback interfaces and tunnel interfaces.

  • A loopback interface is always Up at the physical layer and link layer unless it is manually shut down. You can configure loopback interfaces to enhance network reliability.

  • Tunnel interfaces are used to establish tunnels.

Procedure

  • Creating a logical interface
    1. Choose WAN Access > Logical Interface.

      Figure 12-47  Logical Interface Page

    2. Click Create.
    3. Set parameters in the Create Logical Interface dialog box. The parameters are as described in Table 12-55.

      • Figure 12-48  Create Logical Interface (Interface type is LoopBack)

      • Figure 12-49  Create Logical Interface (Interface type is Tunnel)

      Table 12-55  Logical interface parameters
      Parameter Description
      Interface type Logical interface type.

      Loopback interfaces and tunnel interfaces are supported, see Figure 12-48 and Figure 12-49 respectively.

      Interface number Logical interface number.
      Description Description of an interface.

      By default, the description of an interface is empty.

      IP address IPv4 address of the interface.

      The IP address of the interface cannot conflict with the IP address of any other interfaces or devices.

      NOTE:

      For a loopback interface, this parameter is available when the IPv4 check box is selected.

      Subnet mask Subnet mask of the interface.
      NOTE:

      For a loopback interface, this parameter is available when the IPv4 check box is selected.

      IPv6 address IPv6 address of an interface.
      NOTE:

      This parameter is available only when Interface type is set to LoopBack and the IPv6 check box is selected.

      Subnet prefix length Length of the IPv6 address prefix.
      NOTE:

      This parameter is available only when Interface type is set to LoopBack and the IPv6 check box is selected.

      Tunnel mode This parameter is valid when you create a tunnel interface.

      The following tunnel modes are supported:

      • IPSec
      • GRE
      Source IP Source address of the tunnel interface.
      • Generic Routing Encapsulation (GRE) tunnels use tunnel interfaces at both endpoints of the tunnels. The source address of the local tunnel interface is the destination address of the peer tunnel interface. The destination address of the local tunnel interface is the source address of the peer tunnel interface.

      • Two or more tunnel interfaces encapsulated by the same protocol cannot be configured with the same source or destination address. Two or more point-to-multipoint (P2MP) tunnel interfaces cannot be configured with the same source address.

      Destination IP Destination address of the tunnel interface.

      On GRE tunnels, the source address of the local tunnel interface is the destination address of the peer tunnel interface, and the destination address of the local tunnel interface is the source address of the peer tunnel interface.

      VPN instance VPN instance bound to an interface.
      NOTE:

      Before setting this parameter, you must create a VPN instance. For the detailed procedure, see VPN Instance.

    4. Click OK.
  • Modifying logical interface configuration
    1. Choose WAN Access > Logical Interface
    2. Click corresponding to the logical interface to be configured in the Operation column of Logical Interface List to display the modification page.
    3. Set the parameters described in Table 12-55.
    4. Click OK to complete the configuration.
  • Deleting a logical interface

    1. Choose WAN Access > Logical Interface.

    2. Select the check box next to a logical interface, and click Delete.

    3. Click OK.

  • Disabling a logical interface

    1. Choose WAN Access > Logical Interface to display the Logical Interface page.

    2. Click corresponding to the logical interface to be disabled in the Operation column of Logical Interface List.

    3. Click OK.

  • Enabling a logical interface

    1. Choose WAN Access > Logical Interface to display the Logical Interface page.

    2. Click corresponding to the logical interface to be disabled in the Operation column of Logical Interface List.

    3. Click OK.
