● Path Cost
This parameter is used to calculate the path that will be selected. The path with the
lowest value is selected as the route. If several ports of a device have the same value,
the port with the lowest port number will be selected.
If the value "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.
● Edge Type
Shows the type of the connection. The following values are possible:
– Edge Port
– No Edge Port
● P.t.P. Type
Shows the type of the point-to-point link. The following values are possible:
– P.t.P.
– Shared Media

A n edge port is connected to this port.
There is a spanning tree or rapid spanning tree device at this port.
With half duplex, a point-to-point link is assumed.
W ith a full duplex connection, a point-to-point link is not assumed.
Note
Point-to-point link means a direct connection between two devices. A shared media
connection is, for example, a connection to a hub.
