Displaying more detail in Packet Detail Window

edit

Hi community,

I am wondering if there is a way to display even more detail in the Packet Detail Window? For example, if I were to look at ICMP packets, I see: "Type 8 (Echo (ping) request)" In this example, I see that Wireshark conveniently tells me that an ICMP packet of type 8 is an echo ping request.

My wireshark (ver Version 3.6.2 (v3.6.2-0-g626020d9b3c3) ) is currently, and automatically configured to display these helpful tips in brackets. However, in reading books about Wireshark and using capture files they provided, I am noticing come minute details that are not being displayed when compared to screenshots of the same packets in Wireshark.

One example is TCP packet: Source Port :slc-systemlog (2826)

Where in my Wireshark version, "slc-systemlog " is missing. I am unaware if using a different dissector is a strategy to solve this? The book was written in 2017

Thanks community!
