Setting up listening for incoming packets
The best solution for eliminating the ICMP reject messages is to use the ForwardedMessageSink component to listen for incoming packets. This component allows the packets to be unicast to your computer eliminating the
ICMP reject messages. (ICMP — Internet Control Message Protocol). ICMP reject messages are sent back to the source device
and are included in the Wireshark capture.
Prerequisites: You have added the ForwardedMessageSink component to the MstpPort container in the Nav tree.
You can configure the operating system to expect these messages by setting up a station on the machine running Wireshark and
directing the incoming messages to the “Forwarded Message Sink” listening on the indicated port.
NOTE: You do not need to run a station on your computer. You can add the ForwardedMessageSink component to any location in the station.
Perform the following steps:
- To configure the port, double-click the
ForwardMessageSink.TheForwardMessageSinkproperty sheet opens.
- Set the
Portto the same value used by the forwarder on the controller. - Confirm that
Log Messagesisfalse.While settingLog Messagestotruecreates hex dumps of received messages in the station output, the output can be noisy. It is best to leave the property set tofalseand focus on the information provided by the Wireshark capture.
