两次丢包现场分析如下:

Bole-IGW

  • T9K01-NPB02 于3月19日13:09前后疑似出现{}链路故障{}NZ同时段出现链路告警流量恢复过程造成{}marsio和Firewall同时丢包{}
  • 链路故障的时段,{}T9K02-NPB02{}新建{}会话数出现突增{}CPU和内存使用明显上升造成{}Firewall丢包{}
  •  T9K02-NPB02 于当天的9:30-16:00出现5-6次丢包数量级在100-12k pps之间对应时段monitor策略命中以及Traffic Mirror数量也存在上涨趋势推测丢包原因与策略命中+Mirror有关

LGH-PE

  • T9K01-NPB01 丢包时段3月19日8:00-10:00丢包数量55Kpps+同时触发DDoS Bypassself protection部分包处理线程CPU使用率超过90%
  • 丢包对应时段新建会话和TCP重复包数量也存在突增推测丢包原因与突发流量相关

  • T9K01-NPB02 丢包时段3月19日9:30-15:30丢包数量级100-6kpps同样触发self protection
  • 丢包时段TCP重复包数量和Traffic Mirror的数量也在同步增长推测丢包原因与重复流突增+Mirror命中相关{}{}
