DES-7200 Configuration Guide Chapter 3 NTP
Configuration
! Check the NTP status of client before synchronization
SwitchB(config)#show ntp status
Clock is unsynchronized, stratum 16, no reference clock
nominal freq is 250.0000 Hz, actual freq is 250.0000 Hz, precision is 2**0
reference time is 0.0 (00:00:00.000 UTC Thu, Jan 1, 1970)
clock offset is 0.00000 sec, root delay is 0.00000 sec
root dispersion is 0.00000 msec, peer dispersion is 0.00000 msec
The above information shows that the time hasn't been synchronized yet;
After configuring NTP synchronization, display NTP configurations. Key points:
NTP server address and stratum.
The following log will be printed on CLI interface:
*Sep 8 18:10:37: %SYS-6-CLOCKUPDATE: System clock has been updated to
18:10:37 UTC Tue Sep 8 2009.
SwitchB#show ntp status
Clock is synchronized, stratum 13, reference is 1.1.1.1
nominal freq is 250.0000 Hz, actual freq is 250.0000 Hz, precision is 2**24
reference time is CE511CC9.37EB5B2D (18:11:21.000 UTC Tue, Sep 8, 2009)
clock offset is -0.00107 sec, root delay is 0.00000 sec
root dispersion is 0.00002 msec, peer dispersion is 0.00002 msec
The above information shows that the NTP client has connected to the server
and the time of Switch B has been synchronized with the time of Switch A, with
stratum level being higher than that of Switch A by 1 level (i.e., 13).
