Chapter 3
This situation is likely when the port has many packet errors or the port
constantly loses and regains the link. You should:
• Swap the copper or fiber-optic cable with a known, good cable.
• Look for broken, bent, or missing pins on cable connectors.
• Rule out any bad patch panel connections or media convertors between
the source and destination.
If possible, bypass the patch panel, or eliminate faulty media convertors
(fiber-optic-to-copper).
• Try the cable in another port or interface, if possible, to see if the
problem follows the cable.
Ethernet and Fiber Cables
Make sure that you have the correct cable type for the connection.
• Use Category 3 copper cable for 10 Mb/s UTP connections.
• Category 5, 5e, or 6 UTP or STP cable may be used for 10/100 Mbps
connections.
• For 1000 Mbps (1 gigabit per second) connections, use either Category
5e or Category 6 UTP or STP cable.
• For fiber-optic connectors, verify that you have the correct cable for the
distance and the port type.
• Make sure that the connected device ports both match and use the same
type encoding, optical frequency, and fiber type.
