24 AutoTracker VLAN

Application Examples

This chapter provides specific examples of AutoTracker VLANs in various network configura-
tions. These examples illustrate basic concepts about AutoTracker and highlight issues that
can arise when AutoTracker is used in different network situations.
•Application Example 1 illustrates a network organized according to logical policies and
explains the benefits of a logical network organization.
•Application Example 2 explains unique characteristics of IPX networks that must be consid-
ered when using AutoTracker IPX network address VLANs.
•Application Example 3 highlights an issue concerning translated frames and AutoTracker
IPX network address VLANs.
•Application Example 4 explains how routing works generally in IPX networks and explains
how to avoid an exception condition in which AutoTracker can affect the behavior of an
IPX-routed network.
•Application Example 5 explains why a port-based policy may be required for a VLAN – in
addition to any other policies defined for that VLAN – to establish communications in some
network situations, such as traversing a backbone.
