GE ML1200 instruction manual STP default values, Spanning Tree Protocol STP

SPANNING TREE PROTOCOL (STP) CHAPTER 12: SPANNING TREE PROTOCOL (STP)

While allowing only one active path through a network at any time, STP retains any redundant physical path to serve as a backup (blocked) path in case the existing active path fails. Thus, if an active path fails, STP automatically activates (unblocks) an available backup to serve as the new active path for as long as the original active path is down.

The table below lists the default values of the STP variables. Refer to the following section for detailed explanation on the variables. By default, STP is disabled. To use STP, it has to be manually enabled.
