If this problem occurs because a firmware update was attempted (and failed somehow),
simply retry downloading the new firmware image.
If no firmware update was attempted, please contact LOYTEC support (see Section 13.8).
13.7 IP-852 traffic may flood the entire switched IP network
Problem
In a setup where CNIP routers are used to send data in one direction only (unacknowledged
services), the receiving CNIP router never sends out any data, therefore its position in the
network becomes unknown after a while (due to the aging mechanism of Ethernet switches)
and the traffic is then flooded to the entire network.
Explanation
Ethernet switches use an aging mechanism to store and manage Ethernet MAC addresses.
After some time the switch forgets the MAC address and forwards the Ethernet packets with
the forgotten MAC address to all ports.
Solution
Please activate the keep alive function on the configuration server to establish two-way
communication with the CNIP router.
