Disabling an interface

Before you replace a compact serial cable, or attach your SmartNode to other serial equipment, use the
shutdown command to disable the serial interfaces. This is to prevent anomalies and hardware faults. When
you shut down an interface, it has the state CLOSED in the show port serial command display.
Note
Use the no shutdown command to enable the serial interface after the con-
figuration procedure.

Mode: Administrator execution
Step
1 node (cfg)#port serial slot port
2 node (prt-ser)[ slot/port ]#shutdown
3 node (prt-ser)[ slot/port ]#show port serial Displays the serial interface configuration.
Example: Disabling an interface
The example shows how to disable the built-in serial interface on slot 0 and port 0 of a SmartNode 2300 series
device. Check that in the command output of show port serial State is set to CLOSED.
