ntp master - you provide time to others
ntp server - you do not provide time to others
ntp peer - you provide time to others

> Hi Ed & Anthony, Thank you for your response. Sounds like what I have read through cisco's documentation I might have misunderstood because I have seen references where it says once a system is synchronized it can in turn provide ntp services to others. Is that only when the ntp master command is on this? Just want to confirm.

If your want to provide ntp serviceto others(sounds like that is what you wanna do), you need "ntp master"instead of "ntp server"From Cisco.com :Configuring the System as an Authoritative NTP ServerUse the following command in global configuration mode if you want thesystem to be an authoritative NTP server, even if the system is notsynchronized to an outside time source:CommandPurposeRouter(config)# *ntp master
