            Description

            If TCP/IP has sent an ARP Request to resolve IP to MAC address and the ARP Reply is sent by the sender with the source MAC Address of the netX a wrong entry into ARP cache is made. Thus no IP communication is possible.

            This was only observed in a special environment and in combination with a faulty implementation in another device.
