15.1 VLAN
15.1.1 VLAN
Context
After an interface is added to a VLAN, the interface can forward packets of the VLAN. Devices in a VLAN can directly communicate with each other, whereas devices in different VLANs cannot. Broadcast packets are forwarded within a VLAN.
Procedure
- Creating a VLAN
- Choose .
- In the VLAN List area, click Create. In the Create VLAN dialog box that is displayed, set parameters described in Table 15-1.
- Click OK. The VLAN is added to the VLAN list.
To create more VLANs, repeat steps 2 and 3.
Table 15-1 Parameters for creating a VLANParameter
Description
VLAN ID
ID of the VLAN to be created.
Description
Description of the VLAN.
Link type
Interface type.
For details about interface types, see Table 15-2.
Interface Selection
Adds or deletes interfaces that allow packets from the VLAN to pass through. The procedure for adding or removing interfaces is as follows:- Adding interfaces: Select interfaces in the Available Interfaces area, and click to add the interfaces to the Added Interfacesarea.
- Removing interfaces: Select interfaces in the Added Interfaces area, and click to remove the interfaces back to the Available Interfaces area.

Method of Processing Received Untagged Frames
Method of Processing Received Tagged Frames
Method of Sending Frames
Application
Access interface
Accepts an untagged frame and adds a tag with the default VLAN ID to the frame.
- Accepts a tagged frame if the VLAN ID carried in the frame is the same as the default VLAN ID.
- Discards a tagged frame if the VLAN ID carried in the frame is different from the default VLAN ID.
Removes the tag from a frame and sends the frame.
An access interface connects a switch to a PC and can be added to only one VLAN.
Trunk interface
- Adds a tag with the default VLAN ID to an untagged frame and accepts the frame if the interface permits the default VLAN ID.
- Adds a tag with the default VLAN ID to an untagged frame and discards the frame if the interface denies the default VLAN ID.
- Accepts a tagged frame if the interface permits the VLAN ID carried in the frame.
- Discards a tagged frame if the interface denies the VLAN ID carried in the frame.
- Removes the tag from a received frame and sends the frame if the VLAN ID carried in the frame is the same as the default VLAN ID and permitted by the interface.
- Directly sends a received frame if the VLAN ID carried in the frame is different from the default VLAN ID but permitted by the interface.
A trunk interface can be added to multiple VLANs to send and receive frames for these VLANs. A trunk interface connects a switch to another switch or to a router.
Hybrid interface
Sends a received frame if the interface permits the VLAN ID carried in the frame. A specified command can be used to determine whether a hybrid interface sends frames with or without tags.
A hybrid interface can be added to multiple VLANs to send and receive frames for these VLANs. A hybrid interface can connect a switch to a PC or connect a network device to another network device.

15.1.2 VLANIF
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. A device can use a VLANIF interface to communicate with devices at the network layer.
NOTICE:Assume that the VLANIF interface address is the IP address for logging in to the web platform. If the VLANIF interface is deleted or shut down, you cannot log in to the web platform. If the VLANIF interface IP address is changed, you must use the new IP address to log in to the web platform.
Procedure
- Creating a VLANIF interface
- Choose .
- In the VLANIF area, click Create. In the Create VLANIF dialog box that is displayed, set parameters. Table 15-3 describes parameters for creating a VLANIF interface.
- Click OK. The VLANIF interface is added to the VLANIF interface list.Table 15-3 Parameter for creating a VLANIF interface
