At least one configuration file failed checksum test.
There is no no version.
See flash-disk compare.
Use to force the NVS file system of the redundant SRP module to synchronize
with the NVS file system of the primary SRP module.
If you synchronize the redundant SRP module with the primary SRP module and
the redundant module is armed with a release different from the one it is currently
running, the redundant SRP module is automatically rebooted to load the armed
release.
Optionally, you can use the low-level-check keyword to force the router to
validate all files or only configuration files in NVS, and to synchronize all files
that failed the checksum validation test during the flash-disk-compare command
as well as any other files that are unsynchronized.
When you use the low-level-check keyword, you must also specify one of the
following keywords:
all Validates all files in NVS, and synchronizes all files that failed the
checksum test as well as any other unsynchronized files; this option can
take several minutes to complete.
configuration Validates all configuration files in NVS, and synchronizes all
files that failed the checksum test as well as any other unsynchronized files;
this option takes less time to complete because it validates only a subset of
the files in the NVS file system.
If one or more of the following conditions exist when you use the low-level-check
keyword, the command fails and the router displays a message that explains
why it cannot perform the synchronization:
The router does not contain a redundant SRP module.
