Performs a checksum validation that compares the contents of the NVS file system on the primary SRP module with the contents of the NVS file system on the redundant SRP module, and detects any differences. The command validates only those files that are synchronized between the primary and redundant SRP modules; it does not validate log files, core dump files, and other files that are excluded from the system synchronization process. There is no no version.

- configuration—Compares only configuration files; this option takes less time to complete because it compares only a subset of the files in the NVS file system
