GS750E ping losses
I have a GS750E with firmware 22.214.171.124 (latest), No VLANS (a flat network) it has a single LAG (2 ports), 25 devices, 1 uplink to a 24 port Netgear switch and 1 downlink to an apple airport switch, 23 of the devices are security cameras (mostly Hikvision), the LAG has a Synology NAS and the remaining system is the server used to process data from the security cameras. I have a script running on the NAS that performs a simple ping test with a count of 2 and a wait time of 2 against each of the cameras to ensure that have not hung and this has been running without problems for some time, however there was an issue that caused the camera server to go down for about a week, during which time I would get random ping failures, that went away when the server was brought back into service, leading me to believe that it may be load (or lack of load) related. I mirrored one of the camera ports and attached a laptop running Wireshark to the mirror, what I observed was the following:
I would see a subset of the ICMP requests and the appropriate response for the camera port being mirrored.
I would see ICMP requests for devices not connected to the port and obviously no response as it was not for the connected device.
I'm curious if this has been observed by anyone else and if there are any known issues/ resolutions.
