Figure 3-8 Reference Topology for NTP Analysis An NTP association can be a peer association (one system is willing to synchronize to the other system or to allow the other system to synchronize to it) or a server association (only one system synchronizes to the other system and not the other way around). This is an example of output from the show ntp association command: The Adaptive Security Appliance (ASA) does not sync time with Network Time Protocol (NTP) server when the NTP server sends a dispersion value of more than one second.
