NTP Server Setting

[johnlee43]

Hi,

I have ASA 5520 installed.

I want to use ntp server for firewall clock setting.

I found one open-access ntp server (stratum 2) in Los Angeles:

dmz0.la-archdiocese.net

209.151.225.100

Can I use the following command to set ntp server?

ntp server 209.151.225.100 source outside

Hello John,

Yes, You can,

That's the only command you need (unless running a pre-shared key between the NTP server and client)

Hi,

Thank you for replying.

If we set ntp server setting, how often does firewall access NTP server?

Hello John,

Not sure, I do not have that information on the top of my head,

Maybe you can run a quick debug on your ASA and provide us the answer
