Year 2 - Chapter 7/Cisco 3 -Module 7Novell IPX By Carl Marandola, CCAI-CCNA
Objectives • Explain how Cisco routers are used in NetWare networks • Describe the Novell NetWare protocol suite • Describe Novell IPX addressing • Describe Novell encapsulation • Explain how Novell uses RIP for routing • Describe Service Advertising Protocol • Configure both the router Ethernet and serial interfaces with IPX addresses • Describe how to discover IPX addresses on remote routers • Describe how to verify IPX operation and connectivity between routers • Explain troubleshooting in IPX operations
Novell Protocols • Novell Netware is a proprietary suite of protocols and includes the following: • IPX, a connectionless Layer 3 protocol, that does not require an acknowledgment for each packet and defines the network and node addresses • Novell Routing Information Protocol (RIP), which is different from IP RIP, to facilitate the exchange of routing information • Service Advertising Protocol (SAP) to advertise network services • NetWare Core Protocol (NCP) to provide client-to-server connections and applications • Sequenced Packet Exchange (SPX) service for Layer 4 connection-oriented services
IPX Characteristics • It is used exclusively in a client/server environment. • It uses the network.node IPX addressing structure. • Its logical address contains an interface MAC address. • IPX interface configuration supports multiple data-link encapsulations (to support outdated IOS applications). • Novell RIP uses the distance-vector metrics of ticks and then hops. • Service Advertisement Protocol (SAP) and Get Nearest Server (GNS) broadcasts connect clients and servers.
IPX Addressing The recommended way to get a Novell network address is to ask the network administrator. If you cannot get the address from the network administrator, you can get the IPX address directly from a neighbor router. Telnet to the neighbor router and use the show protocols or show ipx interface command.
Service Advertising Protocol (SAP) Each SAP service is identified by a number: Number SAP Service4 NetWare file server7 Print server24 Remote bridge server (router)
Novell IPX Configuration Tasks • Novell IPX Global Configuration • Assigning IPX Network Numbers to Interfaces • Verifying IPX Operation
