Broadcasts
Receive broadcasts of time information and set interfaces within the system to receive NTP information through broadcast.
NTP is enabled on all active interfaces by default. If you disable NTP on an interface, the system drops any NTP packets sent to
that interface.
1. Set the interface to receive NTP packets in INTERFACE mode.
ntp broadcast client
2. Disable NTP on the interface in INTERFACE mode.
ntp disable
Configure NTP broadcasts
OS10(config)# interface ethernet 1/1/10
OS10(conf-if-eth1/1/10)# ntp broadcast client
Disable NTP broadcasts
OS10(config)# interface ethernet 1/1/10
OS10(conf-if-eth1/1/10)# ntp disable
Source IP address
Configure one interface IP address to include in all NTP packets. The source address of NTP packets is the interface IP address
the system uses to reach the network by default.
● Configure a source IP address for NTP packets in CONFIGURATION mode.
ntp source interface
○ ethernet node/slot/port[:subport]—Enter the Ethernet interface information.
○ port-channel channel-id—Enter the port-channel ID, from 1 to 128.
○ vlan vlan-id—Enter the VLAN ID number, from 1 to 4093.
○ loopback id—Enter the Loopback interface ID number, from 0 to 16383.
○ mgmt node/slot/port—Enter the physical port interface for the Management interface. The default is 1/1/1.
Configure the source IP address
OS10(config)# ntp source ethernet 1/1/10
