Hello all
We have found a decent location for our 2 DCF77 boxe's and I am going to
configure our environment for using these.
Would best practice be to configure 2 core (Cisco) switches to use the two
DCF boxes like this: ntp server (ip of DCF 1) prefer, ntp server (ip of DCF
2) and then hereafter i am considering entering a third "regular" reachable
Ntp-server. Will the servers be prefered in the order they are entered on
the switches?
I will then point all our other networking equipment to the 2 mentioned core
switches for NTP data (in case you in here "ok's" it). How can i make sure
that the core switches is handing out ntp data (is there a special command
for this ?). The reason i am considering a setup like this is, that the DCF
looses their stratum 1 status when (if) they loose connectivity to
Frankfurt. With the setup i describe only the 2 cores switches needs to sync
to another NTP-server (like DCF nr 2 or the 3.rd configured server)
I am realy looking forward to a comment as i am a newbie on this.
Best regards from Denmark
