Csico 9300 and NTP/SNTP

[mljevakovic]

Hi,

does Cisco 9300 support RFC 2030 (SNTP)?

We founded NTP RFC 1305 only.

What exactly are you trying to do?
Are you trying to get the appliance become an SNTP/NTP source (not possible) or an SNTP/NTP client (possible)?

Cisco appliances (whether it is a router, switch, WLC, AP, etc.) need to synchronize their clocks with something "trustworthy".  

With a few hundred dollars one can assemble an NTP server (stratum 1).
