Ethernet: The Definitive Guide
by Charles E. Spurgeon


Following are the changes made in the 9/00 reprint.


Here's a key to the markup:

        [page-number]: serious technical mistake
        {page-number}: minor technical mistake
        <page-number>: important language/formatting problem
        (page-number): language change or minor formatting problem
        ?page-number?: reader question or request for clarification

(32)  Lines 5-6 of the fourth paragraph did read: "Each port of a repeater hub 
links individual Ethernet media segments together..." 

Now reads: "Each port of a repeater hub links an individual Ethernet media 
segment to others..."


(33)  The first line of the second paragraph did read: "...the individual 
ports combine segments..." 

Now reads: "...the ports combine segments..."


(45)  The first sentence of the fourth paragraph did read: "...numerically 
equal to or less than the maximum untagged frame size in octets of 1518 
(decimal)..."

Now reads: "...numerically less than or equal to 1500 (decimal)..."


(78)  The first line of the first paragraph did read: "...gap between each 
frame."

Now reads: "...gap between successive frames."


(83)  The fourth line of the fourth paragraph did read: "...with this opcode 
in the first byte of the data field..."

Now reads: "...with this opcode in the first two bytes of the data field..."


(84)  The MAC address in Figure 4-2 "PAUSE frame" did read: "01-08-C2-00-00-01"

Now reads: "01-80-C2-00-00-01"


(113)  The second to last line of the last paragraph did read: "...male 
jackscrews that connect..."

Now reads: "...male jack screws that connect..."


(113)  The last line on the page did read: "...of 0.5 meters..."

(189)  In the footnote, changed "...speed of light." to "...speed of light in 
vacuum."
 

(229)  Under the heading "Maintain the minimum bending radius" it did read:
"...four times the cable radius."

Now reads: "...four times the cable diameter."


(232)  The first sentence in the second paragraph did read: "The optional 
wiring sequence is widely used in the United States, and many..."

Now reads: "The optional wiring sequence is widely used, and many..."


(258)  The last line of the first paragraph did read: "10BASE-FX."

Now reads: "100BASE-FX"


(280)  The fifth line of the third paragraph did read: "...only two devices
at each end of a given link segment, which limits..."

Now reads: "only two devices on a given link segment; one on each end. This
limits..." 


(282)  The fourth line of the second paragraph did read: "...and two Class II 
repeaters..."

Now reads: "...or two Class II repeaters..."


(295)  The first sentence of the last paragraph did read: "...shown on this 
port is nearly 30 percent of the number... rate for this port is around 30 
percent." 

Now reads: "...shown on this port is nearly 3 percent of the number... rate 
for this port is around 3 percent."


(295)  The third sentence of the last paragraph did read: "...(4,294,967,300 
to be precise)." 

Now reads: "...(4,294,967,296 to be precise)." 


(296)  The first sentence of the first full paragraph did read: "Note that 
this port has counted over 3.4 billion total frames..."

Now reads: "...counted over 363 million total frames..."


(296)  The fourth line of the second paragraph did read: "...and then counted 
another 3.4 billion."

Now reads: "...and then counted another 363 million." 


(296)  The sixth line of the second paragraph did read: "...collision rate is
around 30 percent..."

Now reads: "...collision rate is around 3 percent..."


(296)  The last two sentences of the third paragraph did read: "Now the 
collision rate is less than 3 percent of the total frames. This is a much more 
realistic picture of the current statistics on this port."

Now read: "Once again, the collision rate is around 3 percent of the total 
frames, showing that in this case the original counters were correct. By 
clearing the counter displays and taking a new snapshot, we have verified that 
the collision rate is being correctly reported."


(402)  The last sentence in the first paragraph did read: "...maximum bend..."

Now reads: "...minimum bend..."


(403)  In the first paragraph of the sidebar, in the sixth line, deleted 
"one vendor's set of" from the sentence.
