YGN-MYTEL站点告警的一共是5台TSGX：
|
||
|
||
TSGX006,凌晨1:00-3:00多次触发packet-io drop，丢包1Mpps+，对应firewall无异常指标，推测为非TCP/UDP流量
|
||
|
||
TSGX11，TSG21，TSG22，均出现1次，丢包1.5M~3Mpps+，时间段分布在1:20-1:46，由于超过firewall UDP新建的速率限制，触发UDP overload protection，推测为UDP异常流量
|
||
|
||
TSGX26，出现1次，时段为21:28，丢包100kpps+，同样触发firewall的新建UDP会话 overload protection，推测为UDP异常流量
