428 CHAPTER 16: I NTERNET P ACKET E XCHANGE (IPX)Layer 2SwitchingModules3 MultilayerSwitchingModulesipx interface define Defines an IPX interface on a Multilayer Switching Module.Valid Minimum Abbreviationipx i deImportant Considerationsn An IPX interface defines the relationships among an IPX virtual LAN(VLAN), the IPX router, and the IPX network. The IPX router has oneIPX interface defined for each network that is directly connected to it.n When you define an interface, you define the interface’s IPX address,cost, format, and any associated IPX VLAN index.n Before you define the IPX interface, you must specify a VLAN andselect IPX, IPX-II, IPX-802.2, IPX 802.2 LLC, IPX-802.3, orIPX-802.2-SNAP as a protocol that the VLAN supports, as described inChapter 10. (For routing, a VLAN can support multiple protocols.)n Unless your network has special requirements such as the need forredundant paths, assign a cost of 1 to each interface.n The two Fiber Distributed Data Interface (FDDI) encapsulation formatscorrespond to the Ethernet 802.2 LLC and 802.3 SNAP encapsulationformats. If you select either of these Ethernet encapsulation formats,the corresponding FDDI encapsulation format is automatically selectedfor shared Ethernet and FDDI ports.OptionsPrompt Description Possible Values [Default]IPX networkaddress4-byte IPX address of theinterface.
