Source Interface
Set the source interface for an NTP message.
This configuration makes the source IP address in the NTP
messages the primary IP address of this interface. If the specified
source interface is down, the source IP address is the primary IP
address of the egress interface.
TIP:
If you do not want the IP address of an interface on the local device
to become the destination address of response messages, specify
the source interface for NTP messages.
Key 1
Set NTP authentication key.
Enable the NTP authentication feature for a system running NTP in a
network that requires high security. This feature improves the
network security by means of client-server key authentication, and
prohibits a client from synchronizing with a device that has failed
authentication.
You can set two authentication keys, each of which has a key ID and
a key string.
•
ID
—ID of a key.
•
Key string
—Character string of the MD5 authentication key.
