      Hi,

      There are 2 devices with names "switch1" and "swithc2", which have "Template Module ICMP Ping" only. IPs 192168.180.250 and 192.168.180.251 accordingly.  Problem with ICMP monitoring appeared 2 days ago for both devices ICMP Loss - 85%. Graph pictures are in attachment.

      ICMP default settings have been changed to "icmppingloss[,10,3000,68,3000]", that didn't  fix the problem.

      The test from SSH terminal on Zabbix server shows an absence any issues with ping and fping utilities to these problematic devices.

      Trying to find out the problem:

      1) Disabled the devices "switch1" and "swithc2"

      2) Created  two new devices with names "netgear-switchs-1" and  "netgear-switchs-2" with thae same IPs 192168.180.250 and 192.168.180.251.

      3)  Waited for  minutes, no problem and issues with new created devices "netgear-switchs-1" and  "netgear-switchs-2", no ICMP loss.

      4) Disables new devices "netgear-switchs-1" and "netgear-switchs-2"

      5) Enabled old devices "switch1" and "swithc2", problems with ICMP Loss is still  persisting.
