96. 7 1 4 Path and Port Costs The STP path cost is the main metric by which root and designated ports are chosen The path cost for a designated bridge is the sum of the individual port costs of the links between the root bridge and that designated bridge The port with the lowest path cost is the best route to the root bridge and is chosen as the root port In actuality the primary determinant for root port selection is the root bridge ID Bridge ID is important mainly at network startup when the bridge with the lowest ID is elected as the root bridge After startup when all bridges agree on the root bridge s ID the path cost is used to select root ports If the path costs of candidates for the root port are the same the ID of the peer bridge is used to select the port Finally if candidate root ports have the same path cost and peer bridge ID the port ID of the peer bridge is used to select the root port In all cases the lower ID path cost or port ID is selected as the best 180 Edge Ports RUGGEDCOM ROS Chapter 7 User Guide Spanning Tree How Port Costs Are Generated Port costs can be generated either as a result of link auto negotiation or manual configuration When the link auto negotiation method is used the port cost is derived from the speed of the link This method is useful when a well connected network has been established It can be used when the designer is not too concerned with the resultant topology as long as con
