Note:
In the following three cases, loops cannot been avoided even if
STP function of switch is enabled.
1. Two switches but multiple parallel links. One converge port
configurations and the other does not do so.
2. One switch converge configurations of multiple ports but one
port in the aggregation port group is connected to other ports
of the local equipment in self-loop mode.
3. Two switches but two parallel links. Due to unknown reasons,
both of them cannot receive BPDU packets from the opposite
side.
