Known Issues in NetSim v9
User modified parameters in device properties will not reflect in newly dropped devices
Dynamic metrics not updated on modifying scenario
Packet animation in map view does not show node mobility
Device properties does not revert to default values
Incumbent ID in network and metrics not matching
BGP link speed issues
Dynamic Metrics limit is 500 graphs
Running Application between unconnected nodes
RIP Hop count
Default gateway can’t be empty
Packet size limit in TDMA(Military Radio)
Removing link between switches leads to IP addressing issue
Packet animation simulation time bar is not functioning properly in WSN, IOT
Sliding Window Protocol not working for ‘No error’ condition
Scenario crashes for RTS threshold is ‘0’
Broadcast application with RTS threshold value less than 1480
No Radio Range in map view
Scenario crashes if link name field is left empty
Incumbent placement at the end of the grid
Sensors at grid edge with high velocity for agents leads to crash
IP address issue with connection removal between switch and wired node
Network layer ACK type will need to be reset in DTDMA
Wireless link is wrongly established in MANET

Scenario crashes for RTS threshold is ‘0’
Scenario crashes for RTS threshold is ‘0’
If RTS threshold value is set to ‘0’ in a Wireless node or Access point, then simulation will crash.
