ASR9k, 4.3.4 , 配置2个NTP服务器,每天断一次,然后会自动恢复 ,能找到的最早日志是2019年2月,那时候就开始了。中断之后下一个轮询间隔会自动恢复。
告警消息:
%IP-IP_NTP-5-SYNC_LOSS : Synchronization lost : x.x.x.x: Peer unreachable or clock selection failed
%IP-IP_NTP-5-ALL_CONN_LOST : All NTP peer connections failed.
1024秒之后自动恢复
%IP-IP_NTP-5-LP_CONN_RECOVERED : At least a low priority NTP peer connection was recovered - Stratum 15->4.

其他设备都正常,IOS,NOS,包括其他设备厂家都正常,只有ASR9K会断,而且客户其他数据中心的9K,也是同样问题,每天断一次,有遇到过的吗? 要怎么去定位
求助
