Working with the default RPVST+ configuration
In the factory default configuration, spanning tree operation is disabled. Configuring the spanning tree mode as RPVST+ on a switch and then enabling spanning tree automatically creates a spanning tree instance for each VLAN on the switch. Configuration with default settings is automatic, and in many cases does not require any adjustments. This includes operation with spanning tree regions in your network running STP, MSTP, or RSTP. Also, the switch retains its currently configured spanning tree parameter settings when spanning tree is disabled. Thus, if you disable, then later re-enable spanning tree, the parameter settings will be the same as before spanning tree was disabled.
The switch automatically senses port identity and type, and automatically defines spanning tree parameters for each type, as well as parameters that apply across the switch. Although these parameters can be adjusted, Hewlett Packard Enterprise strongly recommends leaving these settings in their default configurations unless the proposed changes have been supplied by an experienced network administrator who has a strong understanding of RPVST+ operation.
