NTP > 2.5Ms dispersal. 4506, 31% CPU load average.
The accuracy required is < 1Ms.
Most of my devices meet this requirement. What I believe is happening is that this 4506 is loading down and not spending its CPU cycles on NTP calculations. I may be able to rectify this somehow, but not easily I think.
The 6513s seem to never load up and always run low NTP jitter. I am contemplating pointing my hosts at the core 6513s, for NTP, as a solution. I don't think that there is an issue with forwarding NTP packets and repointing the hosts would likely improve accuracy. I am not sure about NTP convergence time impacts though across the network, using a mixture of Linux, AIX, and Windows devices (I'm in an early stage of the solution).
What I would like to figure out is a method of graphing the NTP accuracy parameters of all my Cisco network devices themselves over a large period of time. It would also be useful to associate these plots with CPU utilization on each device.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
