  • 1.  Aruba 2920 NTP Sync Issues

    Posted Aug 15, 2018 04:29 AM

    Hi all,

    Been having some issues trying to get the switch I'm setting up to sync to the windows NTP server. Have copied the input I have used below:

     

    Essella-First-1-Aruba2920(config)# timesync ntp
    Essella-First-1-Aruba2920(config)# ntp unicast
    Essella-First-1-Aruba2920(config)# ntp server 10.33.116.20
    Essella-First-1-Aruba2920(config)# ntp server 10.33.116.20 iburst
    Essella-First-1-Aruba2920(config)# ntp enable
    Essella-First-1-Aruba2920(config)# show time
    Wed Aug 15 10:14:20 2018 (manually set the time previously)


    Essella-First-1-Aruba2920(config)# show ntp status

    Not sure if I have just missed something, was messing around with it for quiet some time yesterday.

    Hello,

     

    Here is the configuration which I have used in my lab that worked for me.

     

    timesync ntp
ntp unicast
ntp server <NTP_Server_IP> iburst
ntp enable
time daylight-time-rule continental-us-and-canada
time timezone -480 (This is a Pacific Time Zone)

    After applying the above commands then, enter the following 'show' commands for verification.

     

     

    show ntp associations detail
show ntp status

    Thank You,
