VLAN

VLAN

VLAN

Context

  • A switch supports 4094 VLANs from VLAN 1 to VLAN 4094.
  • VLANs can isolate the hosts that require no communication with each other, reducing broadcast traffic and improving network security.

Procedure

  • Creating a VLAN
    1. Choose Configuration > Basic Services > VLAN.
    2. Click Create. The Create VLAN dialog box is displayed, as shown in Figure 5-60.

      Figure 5-60 Creating a VLAN

      Table 5-37 describes parameters in the Create VLAN dialog box.

      Table 5-37 Parameters for creating a VLAN

      Parameter

      Description

      VLAN ID

      ID of the VLAN. This parameter is mandatory, and its value ranges from 1 to 4094. VLAN 1 is the default VLAN, and the system will not re-create it.

      Description

      Description of the VLAN. This parameter is optional.

      VLAN attribute

      Attribute of the VLAN. This parameter is mandatory. Set VLAN attribute to Common VLAN or SVF multicast VLAN.

      NOTE:

      This parameter is available only when the device is enabled with SVF.

      IPv4 address

      IPv4 address of a VLANIF interface, such as 10.10.10.1. This parameter is optional and can be configured only for a VLANIF interface.

      Mask

      Subnet mask of the IP address. This parameter is optional.

      IPv6 address

      IPv6 address, such as FC00:0:130F:0:0:9C0:876A:130B. This parameter is optional and can be configured only for a VLANIF interface.

      Prefix length

      Length of an address prefix. This parameter is optional and the value ranges from 1 to 128.

      Intra-VLAN proxy ARP
      Indicates whether to enable ARP proxy in a VLAN:
      • ON: Enable ARP proxy.
      • OFF: Disable ARP proxy.
      NOTE:

      In centralized forwarding, ARP proxy must be enabled in a VLAN.

    3. Set parameters.
    4. Click Add Interface. The Add Interface area is unfolded, as shown in Figure 5-61.

      Figure 5-61 Adding ports to the VLAN

    5. Click Select Interface. The Add Interface page is displayed, as shown in Figure 5-62.

      Figure 5-62 Selecting ports to be added to the VLAN

    6. Click OK. The Create VLAN dialog box is displayed.
    7. Click OK.
  • Creating VLANs in a batch
    1. Choose Configuration > Basic Services > VLAN.
    2. Click Batch Create. The Batch Create VLAN dialog box is displayed, as shown in Figure 5-63. Set parameters.

      Figure 5-63 Creating VLANs in a batch

    3. Click OK.
  • Querying a VLAN
    1. Choose Configuration > Basic Services > VLAN.
    2. Enter the VLAN ID in the search box. If you do not enter any VLAN ID, all created VLANs are displayed.
    3. Click . The VLAN is displayed, as shown in Figure 5-64.

      Figure 5-64 VLAN list

    4. Click View Interface. The interfaces added to VLANs are displayed, as shown in Figure 5-65.

      Figure 5-65 View Interface

  • Modifying a VLAN
    1. Choose Configuration > Basic Services > VLAN.
    2. Click a VLAN ID. The Modify VLAN dialog box is displayed, as shown in Figure 5-66. Table 5-37 describes parameters in the Modify VLAN dialog box.

      Figure 5-66 Modifying a VLAN

    3. Change the values of parameters as required.
    4. Click OK.
  • Deleting a VLAN
    1. Choose Configuration > Basic Services > VLAN.
    2. Select a VLAN to be deleted and click Delete. The system asks you whether to delete the VLAN.

      VLAN 1 is the default VLAN and cannot be deleted.

    3. Click OK.
  • Deleting VLANs in a batch
    1. Choose Configuration > Basic Services > VLAN.
    2. Click Batch Delete. The Batch Delete VLAN dialog box is displayed, as shown in Figure 5-67. Set parameters.

    4. Click OK.

VLAN Pool

Context

A VLAN pool is a combination of multiple VLANs and is used to simplify network deployment. The administrator plans the VLANs of users in a department as a VLAN pool. After a user passes the authentication, the authentication server authorizes the VLAN pool to the user. The device allocates VLANs in the VLAN pool to users based on the VLAN assignment algorithm. In this way, VLANs can be planned for multiple departments without the need of calculating the number of users of each department.

Procedure

  • Create a VLAN pool.
    1. Choose Configuration > Basic Services > VLAN > VLAN Pool.
    2. Click Create. The Create VLAN Pool dialog box is displayed, as shown in Figure 5-68.

      Figure 5-68 Create a VLAN pool

      Table 5-38 describes parameters on the page.

      Table 5-38 Create a VLAN pool

      Parameter

      Description

      VLAN Pool name

      Specifies the name of a VLAN pool.

      VLAN assignment mode
      Specifies the VLAN assignment algorithm in the VLAN pool to Hash or Even.
      • When the VLAN assignment algorithm is set to Hash, VLANs are assigned to users from the VLAN pool based on the hash result of their MAC addresses. As long as the VLANs in the VLAN pool do not change, the users obtain fixed VLAN. A user is preferentially assigned the same IP address when going online at different times.
      • When the VLAN assignment algorithm is set to Even, service VLANs are assigned to users from the VLAN pool based on the order in which users go online. Address pools mapping the service VLANs evenly assign IP addresses to users. If a user goes online many times, it obtains different IP addresses.

      VLAN ID

      Indicates that the specified VLAN is added to the VLAN Pool.

      NOTE:

      This parameter can be configured only after you click and add a VLAN ID to the data area below. Or you can click to clear the data in the text box.

    3. Set the parameters.
    4. Click OK.
  • Modify a VLAN pool.
    1. Choose Configuration > Basic Services > VLAN > VLAN Pool.
    2. Click the name of the VLAN pool in the VLAN pool list. The Modify VLAN Pool page is displayed, as shown in Table 5-38.
    3. Modify the parameters.
    4. Click OK.
  • Delete a VLAN pool.
    1. Choose Configuration > Basic Services > VLAN > VLAN Pool.
    2. Select the VLAN pool to be deleted and click Delete. The system asks you whether to delete the VLAN pool.
    3. Click OK.
  • Refresh VLAN pools.
    1. Choose Configuration > Basic Services > VLAN > VLAN Pool.
    2. Click Refresh.
