  • 1.  NTP Time Sync Issue

    Posted Oct 13, 2023 03:04 PM

    Hello all.  I am currently dealing with a time sync issue with one of my 5406RzI2 switches where it is continually showing me NTP time sync issues in the sys logs.  The switch is configured to point to two internal NTP servers, which are setup the same as all the other switches within my environment. 

    When I run the sh ntp associations detail command, I show the following:

    When I run the show ntp status command, I show the following:

    I have checked my DHCP scope options, and can confirm that they are pointing to the correct NTP & Time Server options, as configured within the switch config.  How would I go about resolving this issue?  Thanks.

    Try adding the iburst option - this should speed up the time to sync.

    timesync ntp
ntp unicast
ntp server 216.239.35.4 iburst
ntp server 216.239.35.8 iburst
ntp server 216.239.35.12 iburst
ntp enable
