Hi!
I consider this as bug as it it makes spanning tree debugging quite complicated.
Problem: It is not possible to retrieve the current path costs (default value
or manually configured) of a Port.
There is information available with:
vs-vsctl get Port $i rstp_status, eg:
{rstp_designated_bridge_id="2.000.98f2b325b4f3",
rstp_designated_path_cost="20000", rstp_designated_port_id="8001",
rstp_port_id="8001", rstp_port_role=Root, rstp_port_state=Forwarding}
There is the field "rstp_designated_path_cost", but this is the total path
costs from the port to the root bridge WITHOUT the Port's own path cost. Hence
a field "rstp-path-cost" would be needed in the rstp_status output to support
tree debugging.
Thanks
Klaus
PS: The same probably applies to STP too
