Command ntp server ip-address Command Mode CONFIGURATION To display the system clock state with respect to NTP, use the show ntp status command from EXEC Privilege mode (Figure 34-2). Figure 34-2. show ntp status Command Example (with respect to NTP) FTOS(conf)#do show ntp status Clock is synchronized, stratum 2, reference is 192.168.1.1 frequency is -369.623 ppm, stability is 53.319 ppm, precision is 4294967279 reference time is CD63BCC2.0CBBD000 (16:54:26.049 UTC Thu Mar 12 2012) clock offset is 997.529984 msec, root delay is 0.00098 sec root dispersion is 10.04271 sec, peer dispersion is 10032.715 msec peer mode is client To display the calculated NTP synchronization variables received from the server that the system will use to synchronize its clock, use the show ntp associations command from EXEC Privilege mode (Figure 34-3).
