Configuring the NTP Client

To configure the device in client mode and specify the NTP servers to synchronize the system clock, use the server command. A maximum of eight NTP servers can be configured. To remove the NTP server configuration, use the no form of the command.

By default, no servers are configured.

device(config-ntp)# server 1.2.3.4 key 1234

device(config-ntp)# server 1:2::3:4 key 1234
