First Printing: August 2007
13th Printing
(Includes previous printings)
Page 110 – 1st paragraph under the note – 1st 2 lines – ICANN actually stands for “Internet Corporation for Assigned Names and Numbers”.
Page 215 – Figure – 8-7 – Change the bold word exit to end.
Page 228, 229 – the table rows for show system:running-config, show nvram:startup-config, and show nvram: should be deleted. IOS doesn’t support this syntax for the running and startup config files for the show command.
Page 240 – Step list, step 2 – the default is actually transport input all, so change the entire step 2 text to read: “If formerly disabled, use either the transport input all or transport input telnet ssh command to tell the switch to accept both Telnet and SSH.”
Page 309 – last paragraph – end of line 2 – “…overlap enough to impact…” – change to “…overlap, so they do not impact…”
Page 487 – Last paragraph – the reference to Ctl-Shift-6 – add after that sentence: “(Note that Ctl-Shift-6 sends a break character; some international keyboards may map a different key sequence to send a break character.)”
Page 499 – figure 15-8 – router R1 – interface number S0/0/1, just below/right of router R1 icon, should instead be “S0/1/1”, to be consistent with earlier figures.
Page 500 – figure 15-9 – same change as page 499, figure 15-8.
12th Printing
(Includes previous printings)
Page 216 – last bullet in list – text “…console line configuration mode…” – should be “…interface configuration mode…”
Page 473 – Question 5 answer B and Question 6 answer D – change 10.1.13.3 to 10.1.13.2.
11th Printing
(Includes previous printings)
Page 67 – 2nd to last paragraph – 2nd to last line – the end of the line currently reads, “…identifying the length of the entire Ethernet frame.” It should instead state “…identifying the length of the data field.”
10th Printing
(Includes previous printings)
Page 445 – Example 14-4 – 5th line with highlighted text – refers to “10.1.128.251” – should instead be “10.1.1.251”. Note that some earlier printings do not have this error.
9th Printing
(Includes previous printings)
Page 24 – 2nd paragraph – begins “The other protocol… HTML”, should not refer to HTML as a protocol. Replace “protocol” with “specification”.
Page 110 – Table 5-5 – the table is inconsistent compared with CD-only appendix I’s table I-7. The table as listed on page 110 is correct.
Page 124 – 2nd to last paragraph – To the end of the last sentence, add the following: “, in this particular topology.”
Page 141 – 1st paragraph after Figure 6-6 – the timer is per TCP segment. To fix the text, in the first line, change "…sets a retransmission timer…" to "…sets a retransmission timer per segment…". In the 3rd line, change "…all segments again." to "…the segment again."
7th Printing
(Includes previous printings)
Page 117 - Step B - 2nd to last line - The text currently reading "R2 forwards the packet..." change the first instance of R2 to R1. The text should now read "R1 forwards the packet..."
Page 311 – Table 11-6 – row whose first column lists DSSS – add "802.11g" to the right column.
Page 352 – 1st paragraph – 3rd line – repeats "two-fifty-five" 4 times – it should instead list that phrase 3 times, followed by "zero", being the wording version of 255.255.255.0.
Page 461 – 2nd bullet point – "…16 seconds ago" should be "…20 seconds ago".
Pg 472 – Figure at bottom of the page – The address on R2’s S0/1 interface should be changed from 10.1.13.3/30 to 10.1.13.2/30.
Page 501 – 1st paragraph – 2nd to last line – text "… link between R1 and R4" should instead be "… link between R3 and R4."
Page 504 – example 15-10 – 3rd and 4th lines – swap the references between FastEthernet 0/0 and FastEthernet 0/1.
Pg 604 - Last definition on page - "CSU/DSU…" Change the word "digital" to "data".
4th Printing
(Includes previous printings)
Page 83 – table 4-2 – 2nd column, 2nd-to-last row – the speed for an E3 is 34.368 Mbps.
Page 119 – paragraph before Step 1 – 2nd line - …Routing protocols follow… " should instead be "…Routers follow…". Then, in steps 2 and 3, change the 1 instance of "router" to "routing protocol". (These changes make the distinction that the routing protocol does the work in steps 2 and 3, but not in step 1.)
Page 192 – table 7-4 – last row, right-most column – the distance per the specifications is 5Km, not 10Km.
Page 308 – last paragraph – 3rd line – "shortwave" should be replaced with "Ultra High Frequency (UHF)".
Page 309 – table 11-5 – first column – "900 KHz" should instead be "900 MHz". In the second column, the "M" in ISM stands for "Medical", not "Mechanical".
Page 430 – last line on the page – "…about 72 MB…" should instead read "…about 384 MB…".
Page 456 - table 14-4 – RIP-1 column – row for "supports autosummarization" – the cell should list "yes", meaning RIP-1 does support autosummarization.
Page 485 – Example 15-3 – 4th line lists "172.16.1.251" – it should instead be "172.16.1.253" to match figure 15-1. Likewise, same page, very last line, replaces "172.16.1.251" with "172.16.1.253".
Page 493 – Example 15-9 – the IP address for interface Fa0/1 should be "192.168.4.30" instead of "192.168.2.23".
Page 495 – 2nd paragraph – 2nd line – "172.31.25.0/25" should instead be "172.31.5.0/25".
Page 495 – 4th paragraph – 3rd line – "…between 172.31.25.1 and 172.31.25.126…" should list a 3rd octet of "5", not "25", in both numbers.
Page 583 – Chapter 11, question 1, answer: Replace answer text with “802.11a uses the U-NNI band of frequencies (around 5.4 GHz). 802.11b and 802.11g use the ISM band (around 2.4 GHz). 802.11i is a security standard.”
Appendix F (CD only) – page 23 – table F-6 – Column 2, last row reads "Not shown", but instead should say "12.2(25)SE".
Appendix F (CD-only) – page 16 – answer to question 6 – reference to "7 seconds" should instead be "9 seconds".
3rd Printing
(Includes previous printings)
Page 156 – figure 6-15 – upper left section – laptop labeled “PC2” should instead be labeled “PC1”.
Page 278 – paragraph after table 10-2 - two instances of the word “enabled” should instead read “disabled”. (1) in the middle of the 3rd line: “…CDP can be easily enabled”, replace “enabled” with “disabled”. (2) towards the end of the 6th line: “Otherwise, CDP can be enabled…”, again replace “enabled” with “disabled”.
Page 279 – figure 10-2 – the PC in the upper left should be labeled “Fred”, with MAC address “0200.1111.1111”.
Page 286 – paragraph before figure 10-3 – 2nd line – “…duplex half…” should instead be “…duplex full…”
Page 394 – table 12-40 – the table should have 10 highlighted lines, as follows, based on the first column: Tables 12-2, 12-3, 12-4, 12-9, the lists on pages 356, 358, and 359, table 12-12, and the two entries labeled as “paragraph”.
Pages 492 and 494 – figures 15-5 and 15-6 – PC11, near the upper left of the figure, should have IP address 10.10.25.1/21, in both figures. As currently listed with IP address 10.10.23.1/21, PC11 would not be in the same subnet as R1’s Fa0/0 interface.
Page 493 – Example 15-9 – the two “interface serial…” commands refer to the wrong serial interfaces – instead of serial 0/0/0 and 0/1/0, the example should list serial 0/0/1 and 0/1/1, respectively.
Page 494 – figure 15-6 – upper right part of figure – text “Subnet 192.168.4.16 /24” should instead end in “…/28”.
2nd Printing
(Includes previous printings)
Page 440 – figure 14-1 – Router “Seville” – IP address 10.1.130.252 should end in “253” instead of “252”.
Page 492 – figure 15-5 – the two bottom routers should be labeled “R3” and “R4”, instead of “R1” and “R2”, respectively.
Page 178 – figure 7-6 – wrong figure. The correct figure is:
Page 207 – last two entries in the bullet list should read “No parity bits” and “1 stop bit”.
