VLANIF

When a switch needs to communicate with the devices at the network layer, you can create a logical interface based on a VLAN on the switch, namely, a VLANIF interface. The VLANIF interface does not exist physically. The S2700SI, S2700EI or S2710SI-52P switches do not support this function.

Context

A VLANIF interface is a Layer 3 interface and can be configured with an IP address. Before creating a VLANIF interface, you must create a VLAN. With a VLANIF interface, the switch can communicate with the devices at the network layer.

CAUTION:

If a VLANIF interface whose IP address is the same as the switch address is deleted or shut down, you cannot log in to the Web system. In this case, you need to change the IP address of the VLANIF interface. After changing the VLANIF address, you must log in to the switch with the new address.

Procedure

• Query VLANIF interface information.
  1. Choose Interface Management > VLANIF in the navigation tree to open the VLANIF page.
  2. Enter the number of the interface that you want to query, for example, 10. If you do not enter any interface number, all VLANIF interfaces are displayed.
  3. Click Query to display all matching records.
  4. Select a record and click Details to view details about the record.
     NOTE:

     To view real-time interface information, click on the VLANIF tag page to refresh the page.

• Create a VLANIF interface.
  1. Choose Interface Management > VLANIF in the navigation tree to open the VLANIF page.
  2. Click New to open the Create VLANIF page.

     Table 1 describes the parameters on the Create VLANIF page.

     Table 1 Create VLANIF

     Parameter		Description
     VLAN ID		Indicates the VLAN ID corresponding to the new VLANIF interface. This parameter is mandatory.
     Status		Indicates the status of the VLANIF interface, which can be enabled or disabled. By default, a VLANIF interface is Up. This parameter is mandatory.
     MTU		Indicates the MTU of the VLANIF interface.
     Description		Indicates the description of the VLANIF interface.
     IPv4 Address	IPv4 Address	Indicates the IPv4 address of the VLANIF interface, for example, 10.10.10.1.
     	Mask	Indicates the mask of the IP address. Select a mask from the drop-down list box.
     	Sub IP Address	Indicates the secondary IP address of the VLANIF interface.
     	Mask	Indicates the mask of the secondary IP address. Select a mask from the drop-down list box. NOTE: The Add and Delete buttons are used to add and delete secondary IP addresses.
