750-882 Media Redundancy ETHERNET Controller
BC protection
Ethernet MTU
Set the MTU value for fragmentation only!
Only set the value for MTU, i.e., the maximum packet size between client and
server, if you are using a tunnel protocol (e.g., 1452 for VPN) for ETHERNET
communication and the packets must be fragmented.
Setting the value is independent of the transmission mode selected.
Configure ETHERNET transmission mode correctly!
A fault configuration of the ETHERNET transmission mode may result in a lost
connection, poor network performance or faulty performance of the fieldbus
coupler/controller.
Broadcast Protection limits the number of broadcast

telegrams per unit of time. If protection is on, the
broadcast packets are limited at 100 Mbit to 8
 
packets per 10 ms and at 10 Mbit to 8 packets per
100 ms. If the limit is exceeded, packets are lost.
Broadcast Protection disabled.
