Usage Guidelines
The show checksum command displays four groups of hexadecimal numbers that act as a digital summary of the contents of the configuration. This same information stores with the configuration when you store it in Flash memory. By using the show config command and viewing the checksum at the end of the configuration listing and using the show checksum command, you can compare the numbers to see if the configuration has changed. The firewall tests the checksum to determine if a configuration has not been corrupted.
