Wireshark : How to capture full Ethernet (link layer) header
I'm doing some research on network traffic analysis with Wireshark. Machine: Macbook Pro, Ventura 13.3.1(a). In Wireshark, I want to check the Ethernet (Data Link layer) headers. I have captured the trace (snapshot as below).
According to the OSI model, the Ethernet layer should have the following headers [Preamble, Dst MAC, Src MAC, Type, Data, FCS]. I am interested to check the FCS value. Unfortunately, I am unable to see this in Wireshark. It seems the NIC is dropping any bad FCS (not passing to Wireshark). Is there any way that I can force NIC to pass bad FCS to Wireshark for analysis?
Thank you,
