VLAN Interface

VLAN Interface

Context

Departments in different network segments need to communicate with each other. The gateway allows communication among different LANs. You can configure and enable interface-based DHCP on VLAN interfaces to dynamically set network parameters such as the IP address for departments in an enterprise, implementing communication among departments.

Procedure

  • Creating a VLAN interface
    1. Choose LAN Access > LAN > VLAN Interface, as shown in Figure 11-2.

      Figure 11-2  VLAN interface configuration page

    2. In the VLAN Interface List area, click Create.
    3. In the Create VLAN Interface dialog box that is displayed, set parameters listed in Table 11-2 based on the site requirements.

      Table 11-2  VLAN interface parameters

      Parameter

      Description

      VLAN interface

      ID of a VLAN to be created.

      Interface status

      Status of a VLAN interface: enabled or disabled.

      Description

      Description of a VLAN interface, for example, HUAWEI, AR Series, Vlanif1 Interface.

      IPv4

      Gateway IP address

      IP address of a VLAN interface, that is, the default gateway IP address of the user host.
      NOTE:
      After reserved IP addresses are added, the gateway IP address cannot be changed. To change the gateway IP address, clear all reserved IP addresses.

      Subnet mask

      Subnet mask of a VLAN interface.
      NOTE:
      After reserved IP addresses are added, the subnet mask cannot be changed. To change the subnet mask, clear all reserved IP addresses.

      Whether to enable DHCP

      Whether to enable or disable the DHCP server function on a VLAN interface. After you enable the DHCP server function on a VLAN interface, users in the corresponding VLAN can obtain IP addresses from the DHCP address pool on the VLAN interface.

      DNS service

      DNS service for VLAN interfaces. The DNS service can be configured only when the DHCP service is enabled. You can select:
      • Using system DNS setting: DNS server IP address allocated by the system, which is the same as the gateway IP address.
      • Specify: DNS IP address specified by the user.

      Primary DNS server

      IP address of the primary DNS server for VLAN interfaces. This parameter is available only when Specify is selected.

      Secondary DNS server

      IP address of the secondary DNS server for VLAN interfaces. This parameter is available only when Specify is selected.

      MTU(Bytes)

      Maximum transmission unit (MTU) of a VLAN interface.

      IPv6

      Gateway IP address

      IP address of a VLAN interface, that is, the default gateway IPv6 address of the user host.
      NOTE:
      After reserved IPv6 addresses are added, the gateway IPv6 address cannot be changed. To change the gateway IPv6 address, clear all reserved IPv6 addresses.

      Subnet mask

      Set the subnet prefix length of the IP address of the VLANIF interface.

      Whether to enable DHCPv6

      Whether to enable or disable the DHCPv6 server function on a VLAN interface. After you enable the DHCPv6 server function on a VLAN interface, users in the corresponding VLAN can obtain IPv6 addresses from the DHCPv6 address pool on the VLAN interface.

      IPv6 DNS service

      IPv6 DNS service for VLAN interfaces. The IPv6 DNS service can be configured only when the DHCPv6 service is enabled. You can select:
      • Using system DNS setting: DNS server IP address allocated by the system, which is the same as the gateway IP address.
      • Specify: DNS IP address specified by the user.

      Primary IPv6 DNS server

      IP address of the primary DNS server for VLAN interfaces. This parameter is available only when Specify is selected.

      Secondary IPv6 DNS server

      IP address of the secondary DNS server for VLAN interfaces. This parameter is available only when Specify is selected.

      IPv6 MTU(Bytes)

      Maximum transmission unit (MTU) of a VLAN interface.

      Available Interface

      Physical interfaces on the device.

      Selected Interface

      Physical interfaces to be added to a VLAN.

      Interface name

      Type and number of a Layer 2 interface.

      Addition mode

      Link type of an interface, including access and trunk.
      • access: An access interface connects to a user terminal and can join only one VLAN.
      • trunk: A trunk interface connects to a switching device and can join multiple VLANs.

      Advanced

      Zone

      A zone to which VLAN interfaces are added.

      VPN instance

      A VPN instance to which VLAN interfaces are added.

    4. Click OK to save the settings.

      To configure multiple VLAN interfaces, repeat steps 2 and 3.

  • Modifying a VLAN interface
    1. Choose LAN Access > LAN > VLAN Interface, as shown in Figure 11-2.
    2. In the VLAN Interface List area, select a VLAN interface, and click .
    3. In the Modify VLAN Interface dialog box, modify parameters listed in Table 11-2. The VLAN interface parameter cannot be modified.

    4. Click OK to save the settings.
  • Deleting a VLAN interface
    1. Choose LAN Access > LAN > VLAN Interface, as shown in Figure 11-2.
    2. In the VLAN Interface List area, select a VLAN interface, and click .
    3. In the dialog box that is displayed, click OK.
  • Adding interfaces to a VLAN
    1. Choose LAN Access > LAN > VLAN Interface, as shown in Figure 11-2.
    2. In the VLAN Interface List area, select a VLAN interface, and click .
    3. In the Modify VLAN Interface dialog box, select interfaces from the Available Interface list, and click , and set Addition mode in the Select Addition Mode dialog box that is displayed. Click OK. The selected interfaces are added to the Selected Interface list. To move interfaces in the Selected Interface list back to the Available Interface list, select interfaces and click . Click OK to add interfaces in the Selected Interface list to the VLAN.

  • Changing the adding mode of an interface
    1. Choose LAN Access > LAN > VLAN Interface, as shown in Figure 11-2.
