Typical NTP Network Configuration
Configuring NTP
Cisco Aironet 1100 Series Access Points do not have a hardware-supported clock, and they cannot
function as an NTP master clock to which peers synchronize themselves when an external NTP source
is not available. These access points also have no hardware support for a calendar. As a result, the
ntp
update-calendar
and the
ntp master
global configuration commands are not available.
