This is probably true for most of the ProCurve line but since I’ve only performed this on a 3500yl and want make any statements other than “I assume it’ll work on most ProCurve switches”. Here’s the steps to set the switch to get it’s time from an NTP server such as us.pool.ntp.org.
- Telnet into your switch.
- Type Menu <Enter>
- System Information <Enter>
- Edit <Enter>
- Arrow down to Time Sync Method and hit <Space> until it’s set to SNTP.
- Arrow down one to SNTP Mode and hit <Space> until it’s set to Unicast and hit <Enter>.
- Arrow to Server Address and enter the address of your NTP server and hit <Enter> (Note: For me I use the ip for us.pool.ntp.org. Since the switch doesn’t offer DNS settings, we put the IP and just hope it doesn’t change…which it does from time to time. If we have a local NTP server, we use this IP)
- Move to Save and hit <Enter>
If your switch has access to the NTP server, it updated the time immediately for me which you’ll see in the top right of your Switch Configuration Menu.
While your here, you probably also want to set the timezone which is an offset in minutes from GMT. For example, EST is -5 hours from GMT so you’d enter -300 and save.
