3.6 VLAN Interface Setup

3.6 VLAN Interface Setup

This section provides information about IEEE 802.1Q TagVLAN interfaces. This section also provides instructions for setting up VLAN interfaces using the FUJITSU PCI GigabitEthernet interface.

3.6.1 IEEE 802.1Q TagVLAN Description

The IEEE 802.1Q TagVLAN function allows the use of two or more different networks with a single physical interface. Each VLAN operates as its own separate network, with its activity separated from other VLANs. To accomplish this, a virtual interface is created by assigning a VLAN ID (VID) to a physical interface. Note that communication between different VID interfaces on the same physical interface is not allowed. The following example shows a VLAN environment.

By using a VLAN, traffic management of two or more networks on a single physical interface can be done.

In order to create a VLAN environment, a switch capable of supporting a VLAN setup (VID and Tagged/Untagged setting) is required.

3.6.2 Setting Up the VLAN Interface

By setting the VLAN interface number to a value greater than 1000, it is possible to distinguish between VLAN interfaces and physical interfaces. The following naming format is used to create the VLAN interface number:

VLAN Interface Number = (1000 * VID) + Physical Instance NumberVLAN Interface Setup Examples:
