ntp for Cisco devices

Our network consists of several Cisco Routers and Switches. The domain Infrastructure is a Windows 2000 domain.

I have gotten an answer back from Microsoft that I can set up one of our 2000 Servers as an NTP server. It is actually called "SNTP" in Microsoft.

What I am unclear about is whether or not their are issues setting up my Cisco Switches and routers to point back to the NTP or "SNTP" server, or whether that will be fine.

I would appreciate any help you can give.

Thank You


Re: ntp for Cisco devices

On routers and IOS switches you should set the NTP server address: "ntp server X.X.X.X". You can assign multiple NTP servers and you'd better issue "ntp update-calender" command. This should be enough for the router'time to be synchronized to the NTP server.


Re: ntp for Cisco devices

Hello we use NTP Windows server in our network

Simply configure in global configuration mode

router(config)#ntp server IP address of NTP server
