Enable NTP
NTP is disabled by default. To enable NTP, congure an NTP server where the system synchronizes. To congure multiple servers, enter
the command multiple times. Multiple servers may impact CPU resources.
• Enter the IP address of the NTP server where the system synchronizes in CONFIGURATION mode.

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.
