Hello. A simple query I hope but I cant get it to work. I want to synchronise the time on HP 5130 switch to a time source elsewhere in our University. On the switch I have tried the following commands but the clock stays stubbornly at 2013.
ntp-service enable
ntp-service unicast-server ip-address-of server
I'm sure this must be really simple but it doesn't work for me. Any advice please?
Thank you.
Solved! Go to Solution.

Interestingly, I can ping the ip address of the timesource from my own PC on VLAN 1 but not from the console of this switch. Maybe I have to tell the switch where to find the timesource?
Thank you.

Re: NTP
Hi
Try to add a default route on your switch to your core switch/router, if that is not yet the case.
Kind regards

Re: NTP
Hi Jonny,
You need to set a default route first to get the connection success, it's better you configure DNS to the switch as well.
ip route-static 0.0.0.0 0.0.0.0 Next Hop (Probably your L3 switch or Router)
dns server 8.8.8.8
then try to ping again, if it does reach and resolve then try check is the NTP able to syncronised or not.
Cheers.

Re: NTP
It also depends on your network firewall. Ensure that Port 123 can get through the firewall.
