Can anyone give me some information on setting up NTP in a home lab - I have been trying to get it working forever, but nothing seems to work.
I have three 3640 routers and a Win laptop connected to a Catalyst switch. Using the "ip helper-address" and "ip forward-protocol" commands, I have successfully configured the laptop as a SNMP server and as a tftp server and achieved communication with all 3 routers. I have never, however, gotten NTP functioning.
On the laptop, I've downloaded Nettime, Meinberg Network Time Protocol, NTP Time Server Monitor and done a lot of research on the IOS commands, but have never had a router receive the correct time from my pc.
Can anyone point me in the right direction or shed some light on what I may be doing wrong, or if I can use a laptop as an NTP server for my routers. Also - what program would you recommend?
Thanks in advance!
The principal problem with trying to use a Windows machine as an NTP server is that Windows uses a simplified time protocol and not actual NTP. But running something like Meinberg should get around that. If the routers are not learning time from the laptop my first guess would be that something is wrong with the Meinberg install or it is not running correctly.
If you believe that Meinberg is running correctly then there is a possibility that there is an issue with the NTP configuration of the routers. If you would post the NTP config from the routers that might help. It might also be helpful if you would post the output of show ntp association detail from at least one of the routers.
