Paul,
Stratum is used to measure the trustworthiness of an ntp source. The number that you see on the other routers is generated by taking the stratum of the master and adding 1 to it. For each hop away from a master 1 is added to the stratum field. For example if you set another router to peer off of one of the routers taking time from the ntp master then the stratum would be 4. The lower the stratum number the more trust worthy the source is because we know it is closer to an ntp master. If you wanted to set the master to appear as the most trust worthy possible then you would set the stratum to 1 as 1 is the lowest stratum.

Subject: NTP Stratum
Hi Everyone,
When I configure NTP stratum as 2 on the NTP master , the other routers show
their stratum numbers as 3.
Why does it always show 1 number higher ?
Thanks,
Paul
