Changing IPX Parameters

The IPX Setup dialog box controls the four frame types, the WAN ports setup, and the advanced tab
enables IPX routing, auto learn of Ethernet network numbers, and the distributed name of the
MultiFRAD.
In IPX based networks using Ethernet, LAN segments can support the use of four different Ethernet
frame formats 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.
For most applications, the RIP and SAP default timers should not have to be changed. Under certain
circumstances, disabling IPX and SPX Watchdog Spoofing in the Bandwidth Optimization group has
proven effective.
Periodic RIP (Routing Information Protocol) refers to broadcasts transmitted from the RIP virtual IPX
port at a given frequency so all MultiFRADs 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. MultiFRADs use these advertisements to build up tables listing the
servers so they can then advertise these servers on the local segments and provide MultiFRADs to
the server. Client workstations can request a list of these servers from the MultiFRAD.
Discard Serialization Packets, when enabled (checked), causes the IPX MultiFRAD 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.
