How configure NTP Cisco ASA firewall?
Set the ASA to get its System Time from an External NTP Source
- Connect to the ASA, go to “enable mode”, then to “Configure terminal mode”
- The IP address I’m using is in the UK if you want one more local look here.
- To check on its status, simply execute a “show ntp status” command.
- Finally save the updated config.
Can Cisco ASA act as NTP server?
Finally, you can configure Cisco devices to act as a time servers, also known as NTP Masters, on your network. Then point all other devices to the NTP Masters to sync.
What is NTP master command?
“ntp master” command is used to make the router act as an ntp server with it’s own hardware clock as a source. i.e. not to be used when you have a real ntp server in your network, or when you can sync to a reliable internet source.
What is NTP in firewall?
Network Time Protocol (NTP) is a protocol that allows the synchronization of system clocks (from desktops to servers). Having synchronized clocks is not only convenient but required for many distributed applications. Therefore the firewall policy must allow the NTP service if the time comes from an external server.
How do I set timezone in Cisco ASA?
Use the clock timezone command to change the timezone. You can pick whatever name you want for the timezone but you have to specify the offset from UTC. CET is 1 hour ahead of UTC so that’s why I configured +1. Summertime starts at the last sunday in march at 02:00 and ends on the last sunday in October, 03:00.

To set the time locally on the ASA (that is, not using Network Time Protocol [NTP]), first navigate to Configuration > Device Setup > System Time > Clock to display the Clock settings window, shown in Figure 6-1.
What is NTP server Cisco?
Network Time Protocol (NTP) is a protocol designed to time-synchronize a network of machines. NTP runs on User Datagram Protocol (UDP), which in turn runs on IP. NTP Version 3 is documented in RFC 1305. This module describes how to configure Network Time Protocol on Cisco devices.
How does Cisco NTP work?
What is NTP server and how it works?
Network Time Protocol (NTP) is an internet protocol used to synchronize with computer clock time sources in a network. It belongs to and is one of the oldest parts of the TCP/IP suite. The term NTP applies to both the protocol and the client-server programs that run on computers.
How do I configure my Cisco router as an NTP server?
