Configuring NTP

NTP services are disabled on all interfaces by default.

Before you begin to configure NTP, you must use the clock set command to set the time on your device to within 1,000 seconds of the Coordinated Universal Time (UTC).

Note: Multicast and broadcast NTP packets are ignored by default.
