IPX Setup
The IPX Virtual Port Setup dialog box controls the four frame types and set up the two WAN ports.
The Advanced tab enables IPX routing, Auto Learn of Ethernet Network Numbers, and the distributed
name of the RouteFinder can be designated or changed.
In IPX based networks using Ethernet, LAN segments can support the use of four different Ethernet
frame formats (RAW, LLC, TYPE_II, and SNAP) over the same physical link provided each frame type
has a unique network address as a virtual port.
NetBIOS, when enabled, enables the transport of Novell encapsulated NetBIOS packets on the
specified virtual IPX port. Refer to Novell documentation regarding NetBIOS operation over NetWare
based LANs. The Hops text box defines the distance, in hops, for the routing of Novell encapsulated
NetBIOS frames on the specified virtual IPX port, and the recommended value is 8.
Periodic RIP (Routing Information Protocol) refers to broadcasts transmitted from the RIP virtual IPX
port at a given frequency so all routers on the internetwork maintain consistent routing tables.
Increasing the frequency of RIP broadcasts can consume excessive bandwidth, especially on low-
speed WAN links. Sixty seconds is the recommended interval between RIP broadcasts.
Periodic SAP (Service Advertisement Protocol) is used in IPX based networks to allow servers
(application servers, file servers, print servers, communication servers, etc.) to advertise their
presence on the internetwork. Routers use these advertisements to build up tables listing the servers
so they can then advertise these servers on the local segments and provide routers to the server.
Client workstations can request a list of these servers from the router.
Discard Serialization Packets, when enabled (checked), causes the IPX router to discard Novell
NetWare File Server serialization security frames received from the specified virtual IPX port. Novell
NetWare File Servers implement broadcast frames, often referred to as security frames, that contain
serialization information regarding the license of the file server executable. This feature permits
filtering of these broadcasts to help reduce WAN traffic and is not intended to interfere with copyright
protection mechanisms. This feature is automatically turned on when Dial-On-Demand is enabled in
PPP port setup.
The default RIP and SAP timer settings should work for most applications. Under certain
circumstances, disabling IPX and SPX Watchdog Spoofing in the Bandwidth Optimization group has
proven effective.
The two IPX WAN Setup dialog boxes allow you to enable or disable IPX routing on the WAN ports,
change the network numbers for the WAN ports, change the default RIP and SAP timers, and optimize
the bandwidth. The IPX WAN network number has to be the same on both ends of the link and must be
unique throughout the internetwork. If a WAN port is configured in a point-to-point operation, both WAN
network numbers have to be the same and unique.
