Protocol Field TCP, ICMP, UDP, IGMP
Hi,
How do i verify the protocol field is correct to help me understand further
If the protocol field has a value of 6 then it would indicate it was TCP.
ICMP protocol would be 1.
UDP protocol would be 17.
IGMP protocol would be 2.

To verify that the value in the Protocol field is correct, you would need to parse the information in the PDU to check if its data format matches the protocol indicated by the Protocol value. For example, if the PDU contains an ICMP message, but the Protocol value int the IPv4 header is 6, you have a mismatch and the Protocol number is assumed to be incorrect.
