When DCE cables are used and when the port is configured in software with the clockrate command
as a DCE port, the bottom LED will light. (See Figure 4-9.) (For a further explanation of the
clockrate command, see the appropriate Cisco IOS software publication.)
Note An error message will be generated if there is a mismatch between the cable and the software
configuration of the port—for example, if the cable is DTE and the clock rate is set, or if the cable
is DCE and the clock rate is not configured.
