You will probably have to ask Cisco or on a Cisco support list.

I don't think you can change the stratum on the server.  Basically, if
you are using GPS or some ultra-precise timekeeping gear, the system
will know and report itself at stratum 1.  Everything else gets its time
from another NTP server and is thus stratum 2.  Now, on the NTP client,
in the config, you can force it to use a particular server at a
particular stratum, but that is a client configuration not a server
configuration option.

I have two servers in my network which get their time from stratum 2
servers and then provide NTP service to the rest of my network.  On any
of the clients on my network, the two local NTP servers show up as
stratum 2.  Again, I have configured nothing special.

Please either ask your company to get rid of this nonsense or post from
a different email account next time.  Please note that such disclaimers
hold practically no legal water anywhere and that you sent your mail to
list with a couple of thousand subscribers and which has archives that
are mirrored on hundreds of servers worldwide.

How comforting.  Two of the worst anti-virus packages you can get.
