show controllers to check the type or health of cables
Modern Cisco Switches support auto-mdix which allows you not to worry so much about the cables connecting the devices. But for the test you have to know this:
straight-through – unlike devices
crossover – for like devices
UTP – unshielded twisted pair is common.
DTE – data terminal equipment.
DCE – data communications equipment.
