I'm trying to get my Adtran 1550 switches to sync time with the DC Controllers, but they all use SNTP version 3. I even tried to sync to time.nist.gov but it also uses SNTP Version 3. Is there a firmware update that updates the sntp on a 1550 to SNTP Version 3? All of 1550 switches are currently running NV1550A-R12-3-2.biz.
There are two ways to configure this SNTP server selection.
(The switch only supports SNTP V1 & V2 and not NTP. )
Assuming your Switch can route to the internet, and has a DNS server configured.
1. CLI configuration mode -
sntp server 2.pool.ntp.org version 2
sntp server pool.ntp.org
2. GUI - System / System summary --- Select Time Server hyperlink in the first System Information window. After making changes, Apply(Bottom) and Save( at the top).
