Hi all,
I'm setting up a FreeBSD box to be used as NTP server within my network, which most of the time will be a stratum 2 NTP.
While I do have some sync problems between the FreeBSD box and the Stratum 1 (work in progress due to a firewall between them) I do see some strange errors on my routers and switches while issuing "show ntp assoc det".
Please see below in bold:

minpoll = 6, maxpoll = 10
While the assoc errors are incrementing, there is another odd thing: the reach value is most of the time 0 (0 the received updates are minimum - 377 constant updates). Now I'm not sure if this value is regarding the stratum 1 NTP or to my NTP (no firewall between these devices).

Can anyone explain how are the assoc errors generated?
Thanks,
