Hsr Coupling Configuration - Siemens SIMATIC NET SCALANCE X-200RNA Operating Instructions Manual

9.8 The "X200" menu
• "Limitation / Max Throughput"
By setting the check mark for "Limitation Enabled", the data throughput from the interlinks
to the PRP ports is limited to the set value. The limitation can be specified with "Max
Throughput". A limitation between 50 and 80% is possible. If the load on the interlinks is
greater than the value set, frames are discarded. This occurs regardless of Ethertypes and any
VLAN priorities.
• "Sliding Window Size"
With this function, you can change the properties of the duplicate filter that filters
redundantly received packets. The default value is 32 (1023 SAs).
When you increase the number of possible "Source MAC addresses", the number of sequence
numbers that can be filtered per "Source MAC address" also increases. At the same time, the
number of "Source MAC addresses" whose packets can be filtered decreases.
When you decrease the number of possible "Source MAC addresses", fewer sequence
numbers can be filtered per "Source MAC address". However, the number of "Source MAC
addresses" that the duplicate filter can filter is increased.
Note
Increasing the "Sliding Window Size" makes sense when there are significant runtime
differences between the PRP_A and PRP_B subnets due to different network topologies.
