This is probably the shortest video I’ve ever made, but the task is really simple — configuring the Simple Network Time Protocol (SNTP) on an HP ProCurve switch.

For reference, here’s the “sntp” commands available in the software:

ProCurve Switch 2610-48(config)# sntp ?
 broadcast             Operate in broadcast mode
 <30-720>              The amount of time between updates of the system clock 
                       via SNTP
 server                Configure SNTP servers to poll time from.
 unicast               Operate in unicast mode
 <cr>

…and, of course, “timesync” takes an argument too…

ProCurve Switch 2610-48(config)# timesync ?
 sntp                  Set the time protocol to SNTP
 timep                 Set the time protocol to the TIME protocol

Pretty simple, huh? Here’s the video:
