cisco 200-301 exam time.... : The peer is statically configured.The address column indicates the address of the NTP peer, and the ref clock column indicates where the peer in the address column gets its time from. The st column indicates the rank of the peer. The when column indicates how long ago the last NTP message was received from this peer. The poll column indicates how often, in seconds, the current router queries the specified peer. The reach column is represented as an octal number ofChapter 17 Cisco Device Management Protocol 429way to indicate the reachability of the peer. The delay column indicates the round-trip time to the peer in milliseconds, and the offset column indicates how much time, in milliseconds, the peer's clock differs from the current router's clock.NTP updates the time of Cisco IOS devices (such as routers) incrementally, so it can take a long time after an IOS device boots before its software clock is fully synchronized with the NTP server. The output of the command show ntp status confirms this One way to speed up synchronization is to manually configure the router's clock to be close to the time that the NTP server advertises. I highly recommend this method if the IOS device's hardware clock battery is dead and needs to be rebooted. After rebooting, set the router's time manually to speed up synchronization; however, the best solution is to make sure the device is on Cisco's SmartNet Service, which allows you to replace the device.The command show ntp status displays the router's NTP status, as follows.IOS# show ntp status Clock is synchronized, stratum 2, reference is 192.168.1.11 nominal freq is 250.0000 Hz, actual freq is 249.9990 Hz, precision is 2** 19 reference time is AFE2525E.70597C87 (00:10:39.511 EDT Thu Jan 12004) clock offset is6.21 msec, root delay is 83.98 msec root dispersion is 81.96 msec, peer dispersion is 2.02 msecIn this example, the IOS device is synchronized with the NTP server with IP address 192.168.1.11, which provides a service level of 2O17.1.4 NTP Configuration Example
