If the value for Admin Path Cost is > 0, this value is adopted as Calculated Path Cost.
If the value for Admin Path Cost = 0, the value for Calculated Path Cost is calculated
automatically. The calculation of the path costs is largely based on the transmission speed.
The higher the achievable transmission speed is, the lower the value for Admin Path Cost
should be.
Typical values for path costs with spanning tree:
● 1000 Mbps = 4
● 100 Mbps = 19
● 10 Mbps = 100
Typical values for path costs with rapid spanning tree:
● 1000 Mbps = 20,000
● 100 Mbps = 200,000
● 10 Mbps = 2,000,000
Admin Point to Point Status
There are three possible settings:
● Point to Point Connection and Shared Media Connection are not selected:
Point-to-point is detected automatically. If the port is set to half duplex, a point-to-point
link is not assumed.
● Shared Media Connection is selected:
Despite a full duplex connection, a point-to-point link is not assumed.
● Point-to-Point Connection is selected:
Despite a half duplex connection, a point-to-point link is assumed.
-to-point means a direct connection between two switches. Shared Media Connection
could, for example, be a conn
ection to a hub.

stpport [<E|D> [ports]] Enables/disables the spanning tree
algorithm for the specified ports.
Administrator only.
If you want to specify
several ports as pa-
rameters, you can sepa-
rate the port numbers
Specifies the priority of the port.
pathcost [<0...65535> [ports]]
Specifies the path costs for the port.
