● Path Cost
This parameter is used to calculate the path that will be selected. The path with the
lowest value is selected. If several ports of a device have the same value, the port with
the lowest port number will be selected.
If the value in the "Cost Calc." box is "0", the automatically calculated value is shown.
Otherwise, the value of the "Cost Calc." box is displayed.
The calculation of the path costs is largely based on the transmission speed. The higher
the achievable transmission speed is, the lower the value of the path costs.
Typical values for path costs with rapid spanning tree:
– 10,000 Mbps = 2,000
– 1000 Mbps = 20,000
– 100 Mbps = 200,000
– 10 Mbps = 2,000,000
You configure the "Cost Calc." on the pages "Layer 2 > Spanning Tree > CIST Port" and
"Layer 2 > Spanning Tree > MST Port".
