Usage Scenario

If current-line-number and save-line-number are not specified, the configuration files are compared from the first lines. The two parameters can be specified to skip the differences that are found and continue the comparison.

The compare configuration command outputs display the current configuration file (including offline configurations) and the saved configuration file from the line that contains differences respectively. By default, the output difference information is restricted to 120 characters.

If the characters from differences to the end of the configuration file are less than 120, the system displays the output difference information till the end of the configuration file.
If the characters from differences to the end of the configuration file are more than 120, the system only displays 120 characters.
