Path Cost
The contribution of the path through this port, when the port is the root port, to the
total cost of the path to the root for this bridge. Value range <1‐65535>.
Port Priority
You can make it more or less likely to become the root port, the lowest number has the
highest priority. Value range <0‐240>, the value must be in steps of 16. Default value is
128.
RSTP system
5.3.4.2
The Rapid Spanning Tree Protocol (RSTP) is a standardized method (IEEE 802.1W) that supersedes the Spanning Tree Algorithm
and Protocol (STP) described as above and provides significantly faster reconfiguration. RSTP is compatible for STP, so the
following content is mostly the same as the above STP description, adding some enhanced performance.
You can view RSTP information about the Root Bridge. Such as following screen.
You can view RSTP port status about the switch. Such as following screen.
