480T routing switch makes your network more fault
tolerant.
STP is a part of the 802.1D bridge specification defined by the IEEE
(Institute of Electrical and Electronics Engineers), a standard-setting
body. To explain STP in terms used by the 802.1D specification, the
switch is referred to as a bridge.
Overview of Spanning Tree Protocol
STP is a bridge-based mechanism for providing fault tolerance on
networks. STP allows you to implement parallel paths for network traffic,
and ensure that the redundant paths are:
• Disabled when the main paths are operational.
• Enabled when the main path fails.
Spanning Tree Domains
You can partition the switch into multiple virtual bridges. Each virtual
bridge can run an independent Spanning Tree instance. Each Spanning
Tree instance is called a Spanning Tree Protocol Domain (STPD). Each
