Aruba 2920 NTP Sync Issues

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.

Re: Aruba 2920 NTP Sync Issues

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,
