How STP Operates
The switch automatically senses port identity and type, and automatically defines port cost and
priority for each type. The console interface allows you to adjust the Cost and Priority for each port. It
also allows you to adjust the mode for each port and the global STP parameter values for the switch.
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.
