15.2.1 Packet Tracer - Configure and Verify NTP

configure and verify ntp addressing table okay n1 is the server and two routers r1 and r2 the ip addresses 225 to 26 to 27 network time protocol ntp synchronizes the time of the amount set of distributed time servers and clients 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 for multiple network devices ntp uses user diagram protocol udp as its transfer protocol all ntp communications use coordinated universal time udc ntp server server n1 is already configured as the ntp server for this topology verify on services ntp okay click on n1 services ntp ntp and is on from r1 pin to the server m1 225 go to r1 command line interface enter enable ping to knight 165 200 to 225 success repeat the ping from r2 go to r2 command line interface enter also on user access mode ping 20165 225 success configure ntp clients cisco devices can be configured to refer an ntp server to use to synchronize their clocks it is important to keep time consistent among all devices configure r1 and r2 as ntp clients so their clocks are synchronized both r1 and r2 will use n1 server as their ntp server they verify the status okay check the current entp and clock settings show ntp and status and show clock detail for example from r1 show ntp status not enabled okay ntp not enable and show clock detail show cloud detail okay is 1993 okay obviously this is not correct and configure r1 and r2 as ntp clients okay configure terminal and use the ntp server command ntp server okay on global configuration modes and set the ip address of the server from 9165 to 100 to 225 configure on r2 okay enable show clock detail okay 1993 configure synchronization configure terminal ntp server to um 9165 235 okay and verify settings check the clocks on r1 and r2 again okay show clock detail go to r1 and show clock detail okay and still is [Music] 1993 okay and wait a minute you need to wait a minute and shock lock the tail again okay so may take a while show clock detail and now you can see 2019 okay time source is ntp and also you can use show ntp status and clock is synchronized strategy number two and reference is the server to level 65 225 you go to r2 and show clock detail 2018 ntp show mtp status and the server 20165 225 very nice okay are the clock synchronized yes r1 and r2 have the same time as the server and one kn1 2019 october 2018 october 12th 2019 october 12th check the status with show ntp status and ntp associations show ntp associations okay r1 this is show ntp status synchronizer the stratum 2 the reference is the ip address of the server and show ntp associations also see asians now you can see the following the the address is the others of the server to on i165 225 go to r2 show ndp associations associations okay the address of the server okay completion 100 thank you very much you
