Command History
Usage Guidelines Use NTP broadcast or multicast associations when time accuracy and reliability requirements are
modest, your network is localized, and the network has more than 20 clients. We recommend that you
use NTP broadcast or multicast associations in networks that have limited bandwidth, system memory,
or CPU resources.
Note Time accuracy is marginally reduced in NTP broadcast associations because information flows only one
way.
This command does not require a license.
