...was repaired...

" messaging, then follow the "

" instructions below. Otherwise, if the condition persists in a reset loop then please contact the GTAC for assistance.

If the second set of messaging ("

code:

...was repaired...

") is seen, then the user should check that the configuration as displayed in the output of a '

code:

' or '

code:

show config

' matches to the backup configuration file taken as of the last known config change. Apply any necessary corrections, but no action is warranted beyond that.
