Configure NTP Broadcasts
With FTOS, you can receive broadcasts of time information. You can set interfaces within the system to
receive NTP information through broadcast.
To configure an interface to receive NTP broadcasts, use the following command in INTERFACE mode:
Disable NTP on an Interface
By default, NTP is enabled on all active interfaces. If you disable NTP on an interface, FTOS drops any
NTP packets sent to that interface.
To disable NTP on an interface, use the following command in INTERFACE mode:
To view whether NTP is configured on the interface, use the
show config command in INTERFACE mode.
If
ntp disable is not listed in the show config command output, NTP is enabled. (The show config command
displays only non-default configuration information.)
Configure a Source IP Address for NTP Packets
By default, the source address of NTP packets is the IP address of the interface used to reach the network.
You can configure one interface’s IP address to be included in all NTP packets.
Task Command Command
Set the interface to receive NTP packets.
