1 Novell NetWare Protocol Stack Media Access Protocols (Ethernet, Token Ring, WAN, others) Physical Data Link Network Session Transport Presentation Application Novell NetWare Protocols OSI Reference Model IPX (Internetwork Packet Exchange) SPX SA P RIP NLSP NETBIOSAPPLICATIONS NCP

2 Key Novell NetWare Features –Address is 80 bits (network.node) –Interface MAC address is part of logical address –Multiple LAN encapsulations per interface –Default routing protocol is IPX RIP –Novell services are advertised using SAP –NetWare clients find servers with GNS packets

3 Novell IPX Addressing E0 E1 S0 48 bits (from MAC) Network.Node 3f.0c56.de34 2c.0c56.de33 Network 4a1d Network 3f Network 2c Up to 32 bits Novell IPX Addressing

4 Cisco Encapsulation Types Novell IPX Name Cisco IOS Name Token-Ring Token-Ring_SNAP Ethernet Token Ring FDDI FDDI_SNAP FDDI_802.2 FDDI_Raw Ethernet_802.3 Ethernet_802.2 Ethernet_II Ethernet_SNAP Specify encapsulation when you configure IPX networks novell-ether sap arpa snap sap snap sap novell-fddi

5 Written Exercise: IPX Parameter Planning –Write the IPX addresses and encapsulation types for R3 Encapsulation Network Address R3 Interface Name S0hdlc S1hdlc E1 novell-ether S0 hdlc Network b001 E0 SAP E1 S1 S1 hdlc S0 Network c0b0 Network d100 Network b1b0 E0 novell-ether R3 R4 E1 b1b0 c0b0 d100 R2 R1

6 Novell Uses IPX RIP for Routing –Uses ticks (about 1/18 sec.) and hop count (maximum of 15 hops) –RIP broadcasts routing information to neighbor routers every 60 seconds, by default –SAP broadcasts NetWare services information to neighbor routers every 60 seconds, by default RIP SAP Tables RIP SAP Tables RIP SAP Tables RIP SAP Tables DCBA
