FIGURE 8-1Example of Servers Supporting Multiple VLANs With Tagging Adapters

The example network has the following features:

The physical LAN network consists of a switch, two servers, and five clients. The LAN is logically organized into three different VLANs, each representing a different IP subnet.

■VLAN 1 is an IP subnet consisting of the Main Server, Client 3, and Client 5. This represents an engineering group.

■VLAN 2 includes the Main Server, Clients 1 and 2 by means of a shared media segment, and Client 5. This is a software development group.

■VLAN 3 includes the Main Server, the Accounting Server and Client 4. This is an accounting group.

The Main Server is a heavily used server that needs to be accessed from all VLANs and IP subnets. The server has a Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter installed. All three IP subnets are accessed by means of the single physical adapter interface. The server is attached to one of the switch’s
