Port Connection Problems
You can usually trace port connection problems to either a poor cable connection
or an improper connection of the port cables at either end of the link. To remedy
these types of problems, make sure that the cable connections are secure and that
the cables connect to the correct ports at both ends of the link.
Port connection problems are also traceable to the autonegotiation mode or the
port interface.
