Usage Guidelines
The DOCSIS specification supports the optional time-stamping of DOCSIS configuration files by
adding a field to the file that shows the time that the file was sent to the CM. This prevents someone from
trying to subvert DOCSIS security by replaying a valid DOCSIS configuration file to another CM. The
timestamp is expressed as the number of seconds since midnight on January 1, 1900.
Examples
The following example shows how to enable timestamp generation for the DOCSIS configuration file.
router(config)#

router(config-file)#
