We have in very few installations experienced issues with IP-output modules rebooting.

Common for these installations are the TV-sets installed. They have all been Samsung ( Tizen OS ver. 3.0).

The root cause of these reboots are the massive amount of ARP data produced by the TV's.

The TDX headend IPTV multicasts are UDP ( one way broadcast...no "receipt" requested) and ARP data are not needed by the headend.

To prevent the TDX IP-output module from rebooting, please configure the network switch port (connected to the TDX AUX port) to prevent data going from the network to the TDX headend.

The Cisco term is "uni-directional Ethernet" (UDE).
