I am ploughing my way through the 1st of the 2 Cisco Press books for the 802 exam. However on page 178 of book 1 (Chapter 7: Ethernet LAN Switching Concepts) 2nd Edition, can anyone confirm if the diagram is incorrect (Fig 7-6)?

The diagram is titled Switch Learning: Empty Table and Adding Two Entries but shows a TCP/ACK conversation with one packet failing. I'm sure that is the exact same picture I saw before in the TCP Fundamentals chapter. Who should I contact?

Yep, Figure 7-6 is the same as 6-6, so you are correct that it is incorrect.

Check the errata on their Web site. If it's not there (and it's not likely it is, since this is a new book), you should contact Cisco Press. Contact info can be found on page iii, in the very front of the book.
