Configuring NTP
Cisco Aironet 1400 Series Bridges 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 bridges 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.
