Check the NTP status and NTP associations by using the following commands to verify NTP operation and configuration.Ĭlock is synchronized, stratum 2, reference is 209.165.200.225Īddress ref clock st when poll reach delay offset disp.

With Packet Tracer you can use the Fast Forward Time button to speed up synchronization.Įxecute the same command on R2. Note : When working on physical routers, allow a few minutes before R1 and R2 clocks are synchronized.

Check the clocks on R1 and R2 again to verify that they are synchronized:.

Use the ntp server command to specify an NTP server, as shown below:

Check the current NTP and clock settings as shown below:.

Both R1 and R2 will use N1 server as their NTP server. Configure R1 and R2 as NTP clients so their clocks are synchronized. It is important to keep time consistent among all devices.

Repeat the ping to N1 from R2 to verify connectivity to N1.Ĭisco devices can be configured to refer to an NTP server to use to synchronize their clocks.

Verify its configuration under Services > NTP. Server N1 is already configured as the NTP Server for this topology.N o more than one packet per minute is necessary to synchronize two devices to within a millisecond of each other. The NTP server then distributes this time across the network. All NTP communications use Coordinated Universal Time (UTC).Īn NTP server usually receives its time from an authoritative time source, such as an atomic clock attached to a time server. NTP uses the User Datagram Protocol (UDP) as its transport protocol.

While there are a number of applications that require synchronized time, this lab will focus on correlating events that are listed in the system log and other time-specific events from multiple network devices.

Network Time Protocol (NTP) synchronizes the time of day among a set of distributed time servers and clients. In this activity, you will configure NTP on R1 and R2 to allow time synchronization.
