SNTP server - IP Address (SG200-08)

Hi Abudef, the host name looks like it is ntp.nic.cz is that correct? To reaffirm, it works with this host name? Can you make a screenshot showing that? Do you have an active internet connection the switch is connecting to? Can you try any other NTP server? Are you on the latest software release for the switch?

Re: SNTP server - IP Address (SG200-08)

Hi Tom,

unfortunately, there is a bug in two latest firmwares which I have tested (1.0.5.1, 1.0.6.2).

To reaffirm, it works with this host name? - Yes, hostname ntp.nic.cz is resolved to an ip address.

Can you make a screenshot showing that? - No, see below.

Do you have an active internet connection the switch is connecting to? - Yes.

Can you try any other NTP server? - Yes. Only private range certain IP addresses are accepted (I have tested class C 192.168.x.x successfully)

I returned the device back to store. I have horrible experience with  RVXXX Small Business routers and their firmware - it does not make any  sense to wait several month for (maybe) corrected firmware

SNTP server - IP Address (SG200-08)

Hi Abudef, I am able to use the server IP address and host name on the big brothers of the SG200-8, a SF300-10 and a SF200-26.

However, these devices are different (and use a different firmware). Sadly I cannot test with a SG200-8 as I don't have one. I will see if I can get some attention to investigate if there's a problem.

SNTP server - IP Address (SG200-08)

I have just checked this on two SG200-08 switches running firmware 1.0.5.1.

I can confirm that there appears to be a problem entering some, but not all, IP addresses, and it doesn't work for 217.31.205.226, with the same error message as described above.
