How do I configure my router as an NTP server?

To define a version of NTP, add the version NUMBER keywords at the end of the command (e.g. ntp server 192.168. 0.100 version 3). To verify NTP status, use the show ntp status command: Floor1#show ntp status Clock is synchronized, stratum 2, reference is 192.168.

What is NTP master command?

“ntp master” command is used to make the router act as an ntp server with it’s own hardware clock as a source. i.e. not to be used when you have a real ntp server in your network, or when you can sync to a reliable internet source.

How to configure the address of the NTP server?

This example shows how to configure the NTP server address, enable NTP client and authentication modes on the switch, and verify the configuration: NTP server 172.20.52.65 with key 879 added. You can set a time zone for the switch to display the time in that time zone. You must enable NTP before you set the time zone.

How does NTP synchronize with distributed time servers?

NTP synchronizes timekeeping among a set of distributed time servers and clients. With this synchronization, you can correlate events to the time that system logs were created and the time that other time-specific events occur. An NTP server must be accessible by the client switch.

Which is version of NTP is used in the overlay network?

NTP Version 3 RFC 1305 is used to synchronize timekeeping among a set of distributed time servers and clients. A set of nodes on a network are identified and configured with NTP and the nodes form a synchronization subnet, sometimes referred to as an overlay network.

Why does NTP work well over non deterministic path lengths?

NTP performs well over the non-deterministic path lengths of packet-switched networks, because it makes robust estimates of the following three key variables in the relationship between a client and a time server. Dispersion of time packet exchanges—A measure of maximum clock error between the two hosts.
