Configuring NTP optional parameters
The configuration tasks in this section are optional tasks. Configure them to improve NTP security,
performance, or reliability.
Specifying the source interface for NTP messages
To prevent interface status changes from causing NTP communication failures, configure the device
to use the IP address of an interface that is always up. For example, you can configure the device to
use a loopback interface as the source IP address for the NTP messages to be sent.
When the device responds to an NTP request, the source IP address of the NTP response is always
the IP address of the interface that has received the NTP request.
Follow these guidelines when you specify the source interface for NTP messages:
•
If you have specified the source interface for NTP messages in the
