2.2.10 Checking the configuration
Run the following commands to check the previous configuration.
Action Command
Check the status and statistics of a
serial interface. display interface serial [ interface-number ]
[ verbose ] [ | { begin | exclude | include }
regular-expression ]
Check the network layer
configuration and statistics of a
serial interface.
display ip interface brief serial interface-number
Run the display interface serial command to view the status and statistics of the interface.
