Spanning Tree Protocol (STP) Bridge Priority Incrementing/Decrementing by One
This feature allows you to configure all STP modes (RSTP/MSTP) bridge priority in increments of 1 or 4,096. Allowing this level of granularity of the priority allows a large range of priority values for the backup root functionality.
After priority reaches 0, backup root is unable to provide for rapid recovery in a lost root situation. In that case, priority returns to its initial configured (or default) value, and the process starts again.
Loss of root should be a rare event, but this feature setting provides a buffer in situations where network downtime to reset the root is not often available.
