We can specify the next-server (tftp server) both globally or specific to a pool. If the next server is configured in both places then the IP specified under the pool will be used. UDP protocols such as NTP can be abused to amplify denial-of-service attack traffic. Servers running the network time protocol (NTP) based on implementations of ntpd prior to version 4.2.7p26 that use the default unrestricted query configuration are susceptible to a reflected denial-of-service (DRDoS) attack. # NTP Binding. The NTP binding is used for displaying the local date and time based update from an NTP server. # Supported Things. This binding supports one ThingType: ntp # Discovery. Discovery is used to place one default item in the inbox as a convenient way to add a Thing for the local time. # Binding Configuration By default it will synchronize its time by using NTP but the timezone might be incorrect.

ntp server 94.125.132.7 source Loopback0 Also, this ntp access-group serve-only 15 means that your router will only serve as a NTP server to the IPs listed on ACL 15, and that's not what you want. Remove this line. If you must, you can set an ACL as shown in Ted Wilmont's post. And you need to check if your server does not require authentication.

The problem with manually setting the time is that if you have hundreds of devices, you need to go into the settings of each device and set the time and date. To avoid this, there is an automatic NTP mechanism, or network time protocol, which synchronizes computer time with the time of network devices.
