5.2.7 IPX (Internet Packet Exchange) Virtual Port Setup
This dialog box allows you to setup configuration parameters for each virtual IPX port. This dialog box is
displayed by clicking on the IPX button in the Router Setup dialog box. IPX is capable of handling different
Ethernet frame types over the same physical link.
In IPX based networks using Ethernet, LAN segments can support the use of four different Ethernet frame
formats. So nodes can use any of the four frame types in a single segment. To support these four frame
types, the RouteFinder treats a single LAN port through which packets of four different frame types can be
sent or received, as four ports. So each port is termed as a Virtual port that maps on to the same physical
port.
IPX Port Enable = [enabled | disabled]
Enables routing of IPX packets on the specified virtual port. Disabling a virtual port disables all IPX routing
activity on the particular virtual port (frame type such as RIP, SAP, forwarding, etc.).
IPX Network = [32 bit hex IPX network number]
Defines a network number for the segment connected to the virtual port. In case auto-learn is enabled (see
IPX General Setup by selecting the Advanced button), you cannot set this field for LAN virtual ports.
IPX Netbios = [enabled | disabled]
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.
IPX Port Netbios Hops = [decimal hop count]
Defines the maximum distance, in hops, for the routing of Novell encapsulated NetBIOS frames on the
specified virtual IPX port.
Recommended value: 08
IPX RIP Broadcast Interval = [decimal seconds]
Defines the time interval between periodic IPX RIP broadcasts transmitted from the specified virtual IPX port.
Periodic RIP broadcasts are required so that all routers on the internetwork maintain consistent routing tables.
Increasing the frequency of RIP broadcasts can consume too much bandwidth specially on low-speed WAN
links.
Recommended value: 60 seconds
IPX Port RIP Aging Timer = [decimal seconds]
Defines the time interval used to age and delete IPX RIP based route entries for the specified virtual IPX port
from the route table. The timer starts when a route entry is created by IPX RIP, updated by IPX RIP, or
referenced for forwarding.
Recommended value: 180 seconds
