IPX Interfaces

IPX Interfaces
An IPX interface has the following information associated with it:
■
IPX network address — A 4-byte address that you assign. Make
each address unique within the network.
■
Cost — A number between 1 and 65534 that the system uses to
calculate route ticks. A tick is an estimate of how long it takes a
packet to reach a network segment. One tick is approximately 1/18 of
a second (there are 18.21 ticks in a second). Assign a cost of 1 to each
IPX interface unless your network has special requirements like the
need for redundant paths.
■
Encapsulation format — Formats that IPX routing uses: Ethernet
Type II, Novell 802.3 Raw, 802.2 LLC, and 802.3 SNAP
■
State — The status of the IPX interface. The IPX interface status can
be up (available for communication) or down (unavailable for
communication).
■
VLAN interface index (VLAN index) — The VLAN that is associated
with a IPX interface. When the system prompts you for this option, it
indicates the available VLAN indexes.
Important
Considerations
Consider the following guidelines when you set up an IPX interface:
■
The first line in an interface display indicates whether:
■
IPX forwarding is enabled
■
IPX RIP mode is active
■
IPX RIP mode triggered updates are enabled
■
IPX SAP mode is active
■
IPX SAP triggered updates are enabled
■
The secondary route/server option is enabled on the system
■
An IPX interface defines the relationships among an IPX VLAN, the IPX
router, and the IPX network. The IPX router has one IPX interface
defined for each network to which it is directly connected.
