STP Configurations
Figure 5-14 shows two possible STP configurations
using SuperStack II Switch units:
■
Configuration 1 — Redundancy for Back-
bone Link
In this configuration, a Switch 1000 and Switch
3000 TX both have STP enabled and are con-
nected by two Fast Ethernet links. STP discovers a
duplicate path and disables one of the links. If
the enabled link breaks, the disabled link
becomes re-enabled, therefore maintaining con-
nectivity.
■
Configuration 2 — Redundancy through
Meshed Backbone
In this configuration, four Switch 3000 TX units
are connected such that there are multiple paths
between each one. STP discovers the duplicate
paths and disables two of the links. If an
enabled link breaks, one of the disabled links
becomes re-enabled, therefore maintaining con-
nectivity.
