In the late 1970s, Xerox created a network protocol called Xerox Network Systems (XNS) that was widely implemented by most major LAN vendors , including Novell, Inc. Novell made some changes to the protocol in the early 1980s, renamed it Internet Packet Exchange protocol (IPX), and incorporated it as part of NetWare. The NetWare transport layer protocol, the Streams Packet Exchange (SPX), was also derived from the XNS protocol suite. Novell NetWare operates over the IPX/SPX protocol suite as well as on the TCP/IP protocol suite.
NetWare is a suite of protocols for sharing resources ”primarily print and file services ”among workstations through a client/server implementation. Novell describes NetWare as a network operating system (NOS) because it gives end users access to resources that are available via the LAN or WAN. NetWare, a dominant corporate NOS, is widely deployed in many internetworks.
Figure 6-1 shows the multiple protocols commonly used in the NetWare protocol suite. We do not cover each of these protocols in this chapter. Instead, we concentrate on explaining the protocols on the network and transport layers ” namely, IPX, IPX Routing Information Protocol (RIP), NetWare Link State Protocol (NLSP), Service Advertisement Protocol (SAP), and SPX. The protocols shown in Figure 6-1 reference other internetwork technologies with which you may be familiar.

Not all revisions of the Cisco IOS support IPX. You must make sure that the IOS version you are running on your router supports the Desktop Protocols Suite .
