Chapter 5: Key Protocols and Interfaces

Figure 34 on page 89 shows an example network that uses VLANs. In this example network, the physical LAN consists of a switch, two servers, and five clients. The LAN is logically organized into three different VLANs, each representing a different IP subnet. The features of this network are described in Table 7.

Description

 

 

 

 

 

 

VLAN #1

 

An IP subnet consisting of the Main Server, PC #3,

 

 

and PC #5. This subnet represents an engineering

 

 

group.

 

 

 

VLAN #2

 

Includes the Main Server, PCs #1 and #2 via shared

 

 

media segment, and PC #5. This VLAN is a software

 

 

development group.

 

 

 

VLAN #3

 

Includes the Main Server, the Accounting Server and

 

 

PC #4. This VLAN is an accounting group.

 

 

 

Main Server

 

A high-use server that needs to be accessed from all

 

 

of the VLANs and IP subnets. The Main Server has an

 

 

Allied Telesyn adapter installed. All three IP subnets

 

 

are accessed via the single physical adapter

 

 

interface. The server is attached to one of the switch

 

 

ports, which is configured for VLANs #1, #2, and #3.

 

 

Both the adapter and the connected switch port have

 

 

tagging turned on. Because of the tagging VLAN

 

 

capabilities of both devices, the server is able to

 

 

communicate on all three IP subnets in this network,

 

 

but continues to maintain broadcast separation

 

 

between all of them.

 

 

 

Accounting

 

Available to VLAN #3 only. The Accounting Server is

Server

 

isolated from all traffic on VLANs #1 and #2. The

 

 

switch port connected to the server has tagging

 

 

turned off.

 

 

 

PCs #1 and

 

Attached to a shared media hub that is then

#2

 

connected to the switch. PCs #1 and #2 belong to

 

 

VLAN #2 only, and are logically in the same IP subnet

 

 

as the Main Server and PC #5. The switch port

 

 

connected to this segment has tagging turned off.

 

 

 

PC #3

 

A member of VLAN #1, PC #3 can communicate only

 

 

with the Main Server and PC #5. Tagging is not

 

 

enabled on PC #3’s switch port.

 

 

 

PC #4

 

A member of VLAN #3, PC #4 can only communicate

 

 

with the servers. Tagging is not enabled on PC #4’s

 

 

switch port.
