Configure a Cisco Router as an NTP Server

An NTP server can provide synchronized dates and times for devices in a network. Since a router cannot be a Stratum 1 device (cannot connect to a Stratum 0 device such as a GPS clock), a router is not an accurate source of time information. If this is not important to you, then using a router as an NTP server may be acceptable.
To configure the router to work as an NTP server, use the following command in configuration mode (following a conf t):
ntp master 8
The “8” specifies the stratum of this NTP server which is essentially the number of hops away from a Stratum 0 device. The default value is “8.”
