NTP / SNTP on HPE Aruba ArubaOS-Switch

Mon, 01 Jan 2024 00:00:00 +0000

How to configure SNTP time synchronisation on HPE Aruba ArubaOS-Switch.

Configuration #

Syntax varies slightly between firmware versions — use whichever your switch accepts:

Current syntax:

cli

sntp unicast
timesync sntp
sntp server priority 1 1.2.3.4

Older syntax:

cli

sntp unicast
timesync sntp
sntp server 1.2.3.4

Replace 1.2.3.4 with your NTP server IP. Domain controllers are a practical choice as they run Windows Time Service automatically.
