无奈了，请指点！

首先到服务器可达吗？
服务器状态正常吗？

aredfox

Router#ping 130.88.200.98

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 130.88.200.98, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 476/476/476 ms
Router#ping 192.43.244.18

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.43.244.18, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 232/236/244 ms


192.43.244.18 其实就是微软给的一个时间服务器time.nist.gov，至少我的几个linux系统可以从上面同步时间。

ssffzz1

ntp server 192.43.244.18

你配置了2个时间服务器。

aredfox

现在设置了一个
Router#show clock detail

Time source is NTP

Router#show ntp status

问题是一样，以前一直也是只用一个。
同步时间的周期再哪里设置？

aredfox

自己做了一个NTPserver 从server上抓包发现，cisco的设备根本就没发NTP包。

cnadl

sh run | i ntp

结果贴出来

aredfox

Router#show run | i ntp
ntp clock-period 17179851
ntp update-calendar
ntp server 192.43.244.18

aredfox

昨天有个朋友说可能是版本问题，准备换个试试，总觉得NTP这东西，看文档说9就支持了。

cnadl

如果你确定这个地址好用的话，试试看ntp ip xx version 2

ntp同步时间间隔不用去管。
