Stratum on NTP

Hi, I have switch-A which is getting time from Switch-B. Switch-B is getting time from Global NTP. My requirement is, Sw-A should get time from B having Stratum- 8. Please help how it is possible.

Hi Rupesh,

The "ntp master 7" command on Switch-B will set its stratum number to 7, then Switch-A's stratum number will be 8.

Re: Stratum on NTP

But, Sw-B is not master, as it is taking time from Other global NTP server. pls suggest as Sw-B is client ot gloabl NTP server.

Re: Stratum on NTP

according to cisco use the "ntp master (statum)" this command with extreme caution. It is very easy to override valid time sources using this command, especially if a low stratum number is configured. Configuring multiple machines in the same network with the ntp master command can cause instability in timekeeping if the machines do not agree on the time.

Re: Stratum on NTP

Rupesh, if switch A is getting ntp from switch B only then why changed the stratum?

Re: Stratum on NTP

I would like to dissuade you from using the "NTP master" command. Can you post your NTP config? I am suspecting your question is not that complicated.
