NTP update shows as down on SG350-10

Cisco SG350-10 on 2.5.5.47

 

My NTP servers list show as down and do not update.

 

If I remove ntp.virginmedia.com and time1.google.com then add them back it shows as up.

check DNS able to resolve - when it down check are you able to ping that domain name?

 

i use public NTP stratum 1 or 2 to get accurate.

DNS is fine as I said when I remove both time severs then add them back in it updates but it does not auto update after that.

Now on firmware 2.5.7.85 same problem god its hard to submit a bug and I can't work out how to open a case for it other then to post here. 

Hello Peter,

 

The easiest way is to contact our technical support centre (STAC) on one of the following numbers: 

 

https://www.cisco.com/c/en/us/support/web/tsd-cisco-small-business-support-center-contacts.html

 

They can further handle your case and eventually file a bug at their discretion.

 

Regards,

Martin

Thier STAC will not let me make a case.

So something not right but the config of the SG350-10 is the same as my old SG300-10 in the end I setup windows to be a NTP server and IP to it which works.

 

DNS is by Bind at 192.168.53.2

VLAN 53 192.168.53.7/255.255.255.224

and VLAN6 192.168.255.254/255.255.255.0 is the source where it goes out for ntp.virginmedia.com

static routes

62.253.128.0/19 next hop 192.168.255.202 VLAN6

80.5.0.0/19 next hop 192.168.255.202 VLAN6

 

Like I say it works the first time and shows as up for ntp.virginmedia.com and then fails to update after that.
