Cisco NTP server behavior

Hello,

I need some clarification regarding how NTP works in Cisco devices.

So right now my client wants to use one of their 6500 series switch as their internal NTP server for development network, but it doesn't seem to work at the moment.

As I understand, 'ntp master' command is needed for router/switch to act as a NTP server, but my colleague says it's not needed.

What I want to know is that if the router has an external NTP source configured (ntp server configured, but no ntp master), would it be possible for other switches to use this router as a NTP server?

Sorry if the question is hard to understand. English is not my first language. :p
