In the parenthesized sentence beginning with "Some letters that …" should the second occurrence of "letters" be "digits"?

3rd paragraph, first sentence

"...802.11 MAC addresses go into ARP tables..."

Shouldn't ARP be in the glossary? I didn't see it there.

2nd Paragraph

In the 3rd line of the 2nd paragraph, there is the sentence: "Robust security network associations are formed when improved the authentication and confidentiality protocols defined in 802.11i are in use."

The order of the following two words should be reversed: "improved the". Then the sentence will read correctly: "Robust security network associations are formed when the improved authentication and confidentiality protocols defined in 802.11i are in use."

Figure 3-13

In Figure 3-13, the 802.1h and RFC1042 encapsulation of Ethernet frame is missing the 2-octet length field between the MAC headers and the SNAP-DSAP header.

In 802.3 standard, section 3.1.1, there must be a 2-octet Length/Type field following the Source Address.

Then section 3.2.6 defines the meaning of this Length/Type field where the bullet a) applies.

This Length field is also described in RFC1042, page 7, "For IEEE 802.3" section, 2nd paragraph. Citation: "The MAC header contains 6 (2) octets of source address, 6 (2) octets of destination address, and 2 octets of length. The MAC trailer contains 4 octets of Frame Check Sequence (FCS), for a total of 18 (10) octets."

1st Paragraph

The portion of the paragraph states: "In essence, LEAP is two MS-CHAP version 1 exchanges. One authenticates the network to the user, and the second authenticates the user to the network"

1) Shouldn't the order be in reverse (i. e., the user is authenticated to network 1st, and the network is authenticated to the user 2nd)?

2) I note in Googling various descriptions of LEAP, others describe using MS-CHAP version 2 for purposes of mutual authentication of the client & server (or supplicant/authentication server).

I believe it would have been more accurate to say the following:

"In essence, LEAP uses MS-CHAP version 2 which can be thought of as two quasi-MS-CHAP version 1 exchanges. The first authenticates the user to the network, and the second exchange authenticates the network to the user"

Or am I missing the obvious?

Figure 7-1 and Figure 7-2

There is a missing arrow from "Temporal Key" to "Phase 2" in both Figure 7-1 and Figure 7-2 since "Phase 2" has 3 inputs and not 2 inputs. This is in the second edition of the book.
