Unstable connection to LAN Extensions

Are you experiencing the LAN extension devices changing state between red and green in Live Monitoring, and it takes several minutes to connect to the devices? Then it might be due to the LAN switch used.

Unmanaged switch

We have seen several projects where the use of specific switches caused the connection to the LAN extensions to be unstable. Specifically, we have seen issues with these devices. 

TP-LINK - Tl-SG1008P


Managed switches

If you experience issues with the connection stability on a managed switch, look into if multi-cast traffic is enabled and try enabling or disabling IGMP to see if that makes any difference. See this article for a short explanation of the data communication between an Impera control system and its extension devices.
