Clock question

Unanswered Question
Jun 12th, 2007

Been looking at the CISCO spec for the 802.11G AP, but I can't find any information on the internal clock (i.e. speed, accuracy, drift, etc). Please help.

I have this problem too.

Hi Ril,

Here is some info on the AP's Internal clock;

Configuring Time and Date Manually

If no other source of time is available, you can manually configure the time and date after the system is restarted. The time remains accurate until the next system restart. Cisco recommends that you use manual configuration only as a last resort. If you have an outside source to which the wireless device can synchronize, you do not need to manually set the system clock.

Understanding Simple Network Time Protocol

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.

Hope this helps!
