518 C 20: IPX R
HAPTER OUTING
When you define an IPX interface, you define:
IPX address
Cost
Format
Associated IPX VLAN index
Before you define the IPX (routing) interface, you must define a VLAN
and select IPX, IPX-II, IPX-802.2, IPX-802.2 LLC, or IPX-802.3-SNAP as
the protocol to be supported by the VLAN. See Chapter 14 for
information about creating VLANs.
Unless your network has special requirements, such as the need for
redundant paths, assign a cost of 1 to each interface and do not
modify this setting.
When you modify an IPX interface, you can change its:
IPX address
Cost
Format
Associated IPX VLAN index
If you use the OddLengthPadding feature (10 MB switching modules
support only), make sure that you select only those interfaces that
require odd-length padding. If you enable this option for every
interface, network performance is degraded.
For more detailed information that explains how to create an IPX
interface, see the Switch 4007 Command Reference Guide.
