Yes. Users can generate pcap trace files which will be read by wireshark.
To enable wireshark packet capture at the node, right click on node -->go to properties --> global properties --> wireshark option. Users can choose online / offline.
Online will open wireshark and display the captured packets as the simulation is running. Offline option will generate the pcap file which can be opening using wireshark post simulation. In general selecting the online option will slow down the simulation
At the end of simulation in the results window, a packet capture option will be displayed. Under that click on Simulation and in the right click on the link (of the node) whose pcap file you wish to open in wireshark.
