mso command in global configuration mode. To delete the information, use the no form of this
command.

Release Modification
12.2(8)YI This command was introduced on the Cisco uBR905 and Cisco uBR925
cable access routers, and the Cisco CVA122 Cable Voice Adapter.
Usage Guidelines This command configures the optional cosigner access start times and organization name that are
specified by Appendix D in the DOCSIS BPI+ specification. The time values are specified as UTC time
values in Greenwich Mean Time, with a two-digit year. If the year is between 50 and 99, it is interpreted
as 1950 to 1999. If the year is between 00 and 49, it is interpreted as 2000 to 2049.
You do not need to use this command unless the MSO or service provider is digitally signing the
Cisco IOS software images that it plans to download to the Cisco cable modems. If so, then this
command must be used to set the appropriate access times and organization name, so that the cable
modem can properly authenticate the software images during a secure software download.
The router uses the codeAccessStart value to verify the cosigner’s Code Verification Signature (CVS)
that is affixed to the code file downloaded using the secure software download feature. The router uses
the ccvAccessStart value to verify the cosigner’s CVC that is affixed to the code file. The router also
uses the organization value to verify that the code file has been signed by the proper MSO or cable
operator.
