ntp source
Use this command to configure an IPv4 or an IPv6 address for the NTP source interface.
This command defines the socket used for NTP messages, and only applies to NTP client
behavior.
Use the no variant of this command to remove the configured IPv4 or IPv6 address from
the NTP source interface.
Syntax
ntp source <source-address>
no ntp source
Default
An IP address is selected based on the most appropriate egress interface used to reach the
NTP peer if a configured NTP client source IP address is unavailable or is an invalid IP
address.
Mode
Global Configuration
Usage
Adding an IPv4 or an IPv6 address allows you to select which source interface NTP uses for
peering. The IPv4 or IPv6 address configured using this command is matched to the
interface.
When selecting a source IP address to use for NTP messages to the peer, if the configured
NTP client source IP address is unavailable then default behavior will apply, and an
alternative source IP address is automatically selected. This IP address is based on the
most appropriate egress interface used to reach the NTP peer. The configured NTP client
source IP may be unavailable if the interface is down, or an invalid IP address is configured
that does not reside on the device.
Note that this command only applies to NTP client behavior. The egress interface that the
NTP messages use to reach the NTP server determined by the
commands.
