![]() | Network Time Protocol (NTP) On Cisco Devices Lab - Part 1 Network Time Protocol (NTP) On Cisco Devices Lab - Part 1 of 3 Cisco devices have a software clock that tracks the time. You'll want to have your devices keep accurate time across your network so that you can correlate events, especially log messages, across a network. If your devices don't maintain a consistent time, then this task becomes difficult to nearly impossible. The preferred method of maintaining consistent time across a network is with the Network Time Protocol (NTP). NTP uses UDP port 123 to provide accurate time updates between devices. There are four versions of NTP. Cisco routers use NTPv3 by default. NTP servers use a hierarchical stratum ranking with the lower stratum being the most accurate. Cisco devices can use NTP(v3) in three different modes: client, symmetric active, and broadcastclient . In this lesson we looked at configuring client mode. As a last resort you can configure one of your Cisco routers to act as an NTP server. 2010年11月26日再生回数 2123 |
![]() | Episode 59: Network Time Protocol This week we cover John Kristoff's "lightning talk" at this years FIRST conference, covering some of our "Network Time Protocol" research and detailing some disturbing findings. John also talks about FIRST and why this group is so important in our community. 2010年07月13日再生回数 845 |
