7.2.4 Comparing Configuration Files

You can compare the current configuration with the initial configuration.
Context
Do as follows on the router:
Procedure
Step 1 Run:
compare configuration [ configuration-file [ current-line-number save-line-
number ] ]
The current configuration is compared with the configuration file for next startup.
If no parameter is set, the comparison begins with the first lines of configuration files. current-
line-number and save-line-number are used to continue the comparison by ignoring the
differences between the configuration files.
When comparing differences between the configuration files, the system displays the contents
of the current configuration file and saved configuration file from the first different line. By
default, 120 characters are displayed for each configuration file. If the number of characters from
the first different line to the end is less than 120, the contents after the first different line are all
displayed.
In comparing the current configurations with the configuration file for next startup, if the
configuration file for next startup is unavailable or its contents are null, the system prompts that
reading files fails.
