Windows 2012 R2 NTP服务器无法与Cisco Nexus同步

我是PDCpipe理员，Windows NTP服务器设置正确，我们有5个不同的时间源设置。 我们能够与其中两个时间源和其他外部时间源（如ntp.org）（以下是configuration）进行同步。 我们知道时间能够同步，它只是无法与Cisco Nexus设备同步（该信息如下）。 我们运行debugging日志，并捕获下面的信息：

151480 15:11:23.7914419s - /-- NTP Packet: 151480 15:11:23.7914419s - | LeapIndicator: 3 - not synchronized; VersionNumber: 3; Mode: 3 - Client; LiVnMode: 0xDB 151480 15:11:23.7914419s - | Stratum: 0 - unspecified or unavailable 151480 15:11:23.7914419s - | Poll Interval: 17 - out of valid range; Precision: -6 - 15.625ms per tick 151480 15:11:23.7914419s - | RootDelay: 0x0000.0000s - unspecified; RootDispersion: 0x0001.03FEs - 1.01559s 151480 15:11:23.7914419s - | ReferenceClockIdentifier: 0x00000000 - unspecified 

我们看到stream量只是不同步，我们已经完成了所有微软的东西，他们已经是可靠的，这台服务器是一个物理而不是虚拟机。 任何帮助将是伟大的。

Cisco Nexus信息：

Windows NTP服务器设置：

• NTP同步时钟与系统时钟一起
• PTP是否比NTP更精确？ 如果是这样，为什么？
• iptables与tor和ntpd玩好
• 一台Linux服务器有两个定时器
• 如何将WIN XP变成一个ntp组播服务器？
