NTP server version not compatible

[bantenor]

Hi,

I have this error log

26-Apr-2022 14:54:35 :%SNTP-D-NTPBADVER: NTP server version not compatible

Cisco SG550X

How to solve this issue?

Did you get this error trying to setup the NTP server? Are you using IP address or DNS name?

[bantenor]

No, all are set. other switches does not get any error. we are using IP address similar to other switches.

Hello,

Can you try setting the version of NTP manually on both devices. If you can only configure the Cisco SG550X then start with version 4 (I think that's the highest) and work your way down to try to be compatible with the remote device.

config t

Device(config)# ntp server <ip-address> version <number>
Device(config)# ntp peer <ip-address> version <number>

Hi David,

how do I check the version for NTP running on SG550X?

I am new to this cisco SMB model.

Thank you!

Try 'show sntp'

It should show the SNTP servers and the versions they are using.

Edit to my last post I think its versions 1-7. But when you go to configure it you can check whats supported.
