8.2.8.7 spanning-tree cost
This command specifies interface path costs. In the initial state, the path costs are
automatically calculated based on data rates. The path costs are automatically
recalculated for any change to the data rates.
For each port, each bridge calculates the total (root path cost) from the designated
costs of received Hello messages and the costs for the specified number of ports.
Then, the port with the lowest total is selected as the root port.
When making this setting for a port-channel port, no setting is required for a physical
link that is part of the target port-channel. The contents of settings made for such
links are not reflected. The setting for a physical link in the port-channel is reflected
in the physical link at the time the link is removed from the port-channel.
