LAN Protocols and TCP/IP docsity.com Module A Preview of Major LAN Protocols docsity.com IPX/SPX Compatible Protocol • Used in Novell networks • Required for interoperability of Windows network with Novell networks • Routable protocol • IPX/SPX can be used for peer-to-peer or client-server networking docsity.com TCP/IP • An important protocol used widely on the Internet • A routable protocol • Supports communication with UNIX networks or any other network that work under the TCP/IP protocol – The base protocol in UNIX networks is TCP/IP • Can be used for configuring peer-to-peer as well as client-server networks of very large scale docsity.com A TCP/IP Application Scenario Workstation The Internet Internet Router Local Router Workstation Lab Configure the workstation for Internet access by Installing TCP/IP. docsity.com TCP/IP Installation and Configuration • A two-step process • First, install the protocol – With many modern OSs such as Windows XP, it is automatically installed • Second, configure its properties – When TCP/IP is automatically installed, the properties are set to be obtained from a DHCP server – However, it is also possible to manually set the properties docsity.com TCP/IP Installation Steps Choose Network/ Properties Install Protocol Choose TCP/IP Start End From Network Neighborhood/ Properties. Add OK TCP/IP protocol installed. docsity.com Accessing the Window for TCP/IP Properties • Under different Windows operating systems the TCP/IP properties are accessed in different ways – The best and the most consistent way to access TCP/IP properties Windows is to go through the Control Panel and then select the Network Icon – Another way to access the properties is to go through Network Neighborhood – Thereafter, select the network properties (Based on the NIC) and then then continue to select the TCP/IP properties docsity.com 3 wat My Computer Hie tits ey File Edit view Favorites Tools Advanced Help y A a é Search [|= Folders iia So Address € Network Connections Mvlkehemi # ih, 1394 Connection aetna elt 4 Connection 2 S Disable aL) La | ed dB Repair Bridge Connections Create Shortcut Ad EJ co j cy ee General | Authentication || Advanced Connect using: gg i B® Broadcom NetXtreme Gigabit Etherne | Configure... a This connection uses the following items: ae es Client for Microsoft Networks osoft Networks ction | Install... | I Fropeties | Transmission Control Protocol/lnternet Protocol.
