Hi Esteban,


The commands for this changed from NTP to SNTP somewhere in the 12.2.x releases. Here is some info for 12.3.(4)JA;


Managing the System Time and Date


You can manage the system time and date on the wireless device automatically, using the Simple Network Time Protocol (SNTP), or manually, by setting the time and date on the wireless device.


Simple Network Time Protocol (SNTP) is a simplified, client-only version of NTP. SNTP can only receive the time from NTP servers; it cannot be used to provide time services to other systems. SNTP typically provides time within 100 milliseconds of the accurate time, but it does not provide the complex filtering and statistical mechanisms of NTP.


You can configure SNTP to request and accept packets from configured servers or to accept NTP broadcast packets from any source. When multiple sources are sending NTP packets, the server with the best stratum is selected.


If multiple servers are at the same stratum, a configured server is preferred over a broadcast server. If multiple servers pass both tests, the first one to send a time packet is selected. SNTP will only choose a new server if it stops receiving packets from the currently selected server, or if a better server (according to the above criteria) is discovered.


Configuring SNTP


SNTP is disabled by default. To enable SNTP on the access point, use one or both of these commands in global configuration mode:


sntp server {address | hostname}

[version number]

Configures SNTP to request NTP packets from an NTP server.


sntp broadcast client

Configures SNTP to accept NTP packets from any NTP broadcast server


Enter the sntp server command once for each NTP server. The NTP servers must be configured to respond to the SNTP messages from the access point.


If you enter both the sntp server command and the sntp broadcast client command, the access point will accept time from a broadcast server but prefers time from a configured server, assuming the strata are equal. To display information about SNTP, use the show sntp EXEC command.

Hope this helps!
