The value of sysUpTime when the running configuration
was last saved (written).
If the value of ccmHistoryRunningLastChanged is greater than
ccmHistoryRunningLastSaved, the configuration has been
changed but not saved.
What constitutes a safe saving of the running
configuration is a management policy issue beyond the
scope of this MIB. For some installations, writing the
running configuration to a terminal may be a way of
capturing and saving it. Others may use local or
remote storage. Thus ANY write is considered saving
for the purposes of the MIB.
