Viewing TOP Server OPC UA Wireshark Trace

How do I read a TOP Server OPC UA trace captured by Wireshark?

Wireshark can filter on OPC UA using the filter string 'opcua'.  In order for Wireshark to show TOP Server OPC UA communications, you will need to configure the OpcUa filter to support port 49380. (The default port in TOP Server is 49380. If another port was specified, you would need to add that port.)

This port configuration is located within the Edit ⇒ Preferences menu, within the Protocols ⇒ OpcUa.
