Re: Jan 22 22:21:05: NTP: Drift exceeds +392ppm, cannot cope
This just means that the NTP server that this router is synching with is drifting it's expected time. (below more details). This might be a problem with what ever is your NTP server.
The frequency tolerance of computer clock oscillators can vary widely, which can put a strain on the daemon's ability to compensate for the intrinsic frequency error. While the daemon can handle frequency errors up to 500 parts-per-million (PPM), or 43 seconds per day, values much above 100 PPM reduce the headroom and increase the time to learn the particular value and record it in the ntp.drift file. In extreme cases before the particular oscillator frequency error has been determined, the residual system time offsets can sweep from one extreme to the other of the 128-ms tracking window only for the behavior to repeat at 900-s intervals until the measurements have converged.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
