Rule 3: No more than ten active Spanning Tree components in the topology
when using Spanning Tree default settings
The ability to disintegrate any topology to form a tree without loops requires a complex
protocol that works with several variable timers. These variable timers are dimensioned
using IEEE standard default values so that a topology with a maximum of ten active
Spanning Tree components always results in a stable network. When using large tree,
please note the following (see also Section "Large Tree Support" on page 5-5):
–
In the large tree support RSTP topology,
do not
use devices that
do not
support
large tree support.
–
Enable the large tree support option on
all
devices.
–
If RSTP is to be activated as the redundancy mechanism in an existing network
with more than seven switches along the relevant path, then the large tree support
option must first be enabled on all devices.
–
It is recommended that large tree support is not activated in networks with less than
seven switches along the relevant path.
