Juniper JUNOSE 11.3, Configuration Manual

•
Use to perform 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.
•
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.
•
Specify one of the following keywords:
•
all —Compares all files in NVS; this option can take several minutes to complete.
•
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.
•
If all files pass the validation test, the router reports that all checksums matched and
displays the total number of files and total number of bytes of information compared.
•
If one or more files fail the validation test, the router reports a checksum test failure
and does not display the total number of files and bytes compared.
•
If one or more of the following conditions exist, the command fails and the router
displays a message that explains why it cannot perform the checksum test:
•
The file systems on the primary flash card and the redundant flash card are not
synchronized.
•
The router does not contain a redundant SRP module.
•
The redundant SRP module is offline.
•
