This is a short guide on how to set up NTP time synchronisation on HP Network devices. I’ll be covering SNTP settings in this guide, as well as some of the niftier things that aren’t in the manuals but still are really handy. NTP time synchronisation allows you to maintain correct time across your network, which is very important for troubleshooting when comparing logs between two switches for example.

When configuring network hardware over the network itself it’s very easy to issue a command that breaks the network connection to the switch, requiring you to visit the switch and connect to it with a console cable to fix the issue. This is not a big problem if the switch is just down the hall in a closet somewhere, but in today’s world a switch that you’re configuring might be hundred of miles away from where you’re sitting.
Of course this whole issue can be sidestepped by just thinking through what you’re doing before hitting the enter key, but in the real world this is not always an available luxury.
The solution to this problem is to cleverly utilize the “reload” command in combination with the “write” command.
