General Notes CD-ROM only - To find the subnetting practice CD-only appendix: Put the CD
into your CD drive. It should bring up an application automatically; if
not, run the autorun.exe file on the CD. The menu lists an option for
"Hands-on exercises and Boson NetSim LE for CCNA." Click that option, and
the next menu will list an option for the CD-only subnetting practice
appendix. You can download a free CD exam engine upgrade, which fixes all known
problems and provides you with an additional free 150 practice test
questions, by clicking "Downloads" under "More Information" on the
ciscopress.com book catalog page. Note about page numbering: The 8th printing (and later) of this book
include about 18 additional pages in chapter 6. As a result, some of the
page number references in this errata file show a page number for printings
1-7, and a page number for printings 8 and beyond. Look at the first
printed page inside the front cover of your book in order to discover the
printing for your book. 17th Printing
(Entries in this section apply to the 1st - 17th printings) Page 74 - Figure 3-4 - the field labeled "Etype" in the frame labeled
"Tagged Frame" does not exist, and should be removed. The actual first
three fields, read left-to-right, are Dest, Src, and tag, shorthand for
destination address, source address, and tag. The first two bytes of the
tag then hold a protocol type field. Page 142 - question 1 - the wording of the question may be ambiguous;
change the question text to read as follows: "What one action listed in the
answers directly causes a router to list a route with the code "S" in the
output of the show ip route command?" Page 156 - gray note at the bottom of the page - IGRP's maximum metric is
2^16 - 1, which is 65,535, instead of the listed "four billion". Same error
on page 160, table 5-8, and page 180, table 5-17. Page 218 - example 6-5 - output from the show ip ospf neighbor command -
the line listing neighbor ID 172.31.12.201 should have a state of
"FULL/DROTHER", and the line with neighbor ID 172.31.230.3 should have a
state of "FULL/DR", in order to match the next command's output. Page 519 (printings 1-7) and page 537 (printing 8 and beyond) - question 6
- the answer should be "B", not "B and D". The answer text should be
replaced with "Answer B matches all IP addresses that begin with 10, so it
matches all interfaces. Answer D matches all interfaces whose addresses
begin with 10, and end with 1, which also matches all interfaces - however,
an OSPF wildcard mask cannot intersperse binary 0's and 1's, instead having
only (at most) 1 sunbroken string of binary 1's and 1 unbroken string of
binary 0's." Page 520 (printings 1-7) or 538 (printing 8 and later) - question 10, top
of the page - the correct answers are A, C. Page 550 - question 3 - the correct answers are E, F, G, instead of just E,
G. Page 635 - last paragraph before figure F-5 - the "C" in FECN and BECN
stands for "congestion", not "correction" 13th Printing
(Entries in this section apply to the 1st - 13th printings) Page 222 - paragraph before example 6-7 - 2nd line - text "(Figure 6-7)"
should instead be "(Figure 6-9)". Page 386 - question 23 - the question's answer is incorrect; please
disregard this question. Page 466 (prints 1-7) or page 484 (print 8 and later) - Examples 13-5 -
the command prompts should all include "(config-if)", instead of just
"(config)", as the commands in the example are all interface configuration
commands. 12th Printing
(Entries in this section apply to the 1st - 12th printings) Page 45 - paragraph underneath table 2-5 - 5th line - "MaxAge timer
(default 20 seconds)" should instead be "Forward Delay timer (default 15
seconds) Page 209 (prints 1-7) or page 222 (print 8 and later) - table 6-7 - The
"network network-number [network-mask]" command should list "wildcard-mask"
instead of "network-mask". Page 330 (prints 1-7) or page 348 (print 8 and later) - figure 10-2 - The
references to SS7 on the left and right side should not be there. Signaling
between the routers and the local switch uses Q.931. SS7 is indeed used in
the center of the network. Page 336 (prints 1-7) or page 354 (print 8 and later) - 2nd paragraph - 4th
through 6th lines - the E1-based PRI uses channel 0 for framing, channel 16
(not 15) for the D-channel, and the rest (1-15 and 17-31) as B-channels. Page 349 (prints 1-7) or page 367 (prints 8 and later) - example 10-7 -
3rd and 4th lines - The text reads "LCP Open" and "Open: LCP, CDPCP".
Instead, these two lines should read "LCP Closed" and "Open:" Page 518 (through printing 7) and page 536 (printings 8 and later) -
(Answer to the Q&A #21 in Chapter 5) - The answer should be referencing
mask 255.255.252.0, instead of mask 255.255.255.252. Page 537 - (Applies only to 9th printing and later) - bottom of page,
answer to question 9 should be "I", meaning the answer next to letter "I"
in question 9 on page 188. Page 530 (printings 7 and earlier) or page 548 (printings 8 and later) -
Question 6 answer - "200.1.1.0" should be "200.1.1.1".
9th Printing
(Entries in this section apply to the 1st - 9th printings) Page 361 (prints 1-7) 2nd paragraph, 2nd line, or Page 379 (prints 8 and
later), 3rd paragraph, 2nd line - change "25 percent" to "10 percent". At
the end of the paragraph, add the line "(note: the load percentage is
calculated as x/255, with x being the configured load value.)". Page 465 (prints 1-7) or page 483 (print 8 and later) - Examples 13-1, 13-
2, and 13-3 - the frame-relay interface-dlci commands are not actually
needed in order for this configuration to work. The commands may be
deleted.
8th Printing
(Entries in this section apply to the 1st - 8th printings) Page 21 - 3rd printed line from the bottom - the "ip default-gateway
10.1.1.1" command should use a different IP address, as 10.1.1.1 was
already assigned to this switches VLAN 1 interface. Replace "ip default-
gateway 10.1.1.1" with "ip default-gateway 10.1.1.2". Page 84 - 2nd to last line on the page - "The 2950..." should be "Sw2-
2950..." Page 131 - 2nd paragraph - bolded command "ip zero-subnet" should instead
be "ip subnet-zero". Page 139 - question 21 - The question is a duplicate of questions 20, and
should be ignored. Also, the answer to this question, listed on page 531,
is incorrect and should also be ignored. Page 146 - last paragraph, first line - address "10.1.128.2" should be
"10.1.128.252". Page 207 (prints 1-7) or page 215 (print 8) - example 6-4 - the "network
10.0.0.0 area 1" command should be "network 10.0.0.0 0.255.255.255 area 1" Page 259 (prints 1-7) or page 277 (print 8) - 2nd paragraph - 5th line -
"192.8.17" should be "192.8.3.17", and "192.8.30" should be "192.8.3.30". Page 275 (prints 1-7) or page 293 (print 8) -paragraph before figure 8-10
- 3rd line - The last octets of the two IP addresses are litsed as "49" and
"50"; they should instead be "249" and "250". Page 318 (prints 1-7) or page 336 (print 8) - question 9 - the answer is
not covered in the book. The question can be ignored. Page 332 (prints 1-7) or page 350 (print 8) - figure 10-3 - Beside router
D, phrase "Uses Serial interface" should instead read "Uses ISDN
interface". Page 333 (prints 1-7) or page 351 (print 8) - table 10-5 - last row, last
column - should read ""ISDN card, S/T interface".
Page 346 (prints 1-7) or page 364 (print 8) - example 10-6 - interface
bri0 needs the subcommand "ip address 172.16.2.1 255.255.255.0". Page 353 (prints 1-7) or page 371 (print 8) - top paragraph - last line -
"0 through 3" should be "0 through 23". Page 376 (print 8 and beyond) - 4th paragraph - bold command "dialer remote-
host" should instead be "dialer remote-name". Page 364 (prints 1-7) or page 382 (print 8) - figure 10-13 - same change as
figure 10-3, page 332. Page 473 (prints 1-7) or page 491 (print 8) - Answer to question 9 - IGRP
disables split horizon only on physical interfaces; it is enabled for
either type of subinterface. Page 520 (prints 1-7) or page 538 (print 8) - question 1 - configuration
snippet - the first occurrence of "interface serial 0/1" should instead be
"interface serial 0/0". Page 570 (prints 1-7) or page 588 (print 8) - table D-1 - last row, last
column - third sentence says, "So, only classful routing protocols support
VLSM". It should instead say "So, only classless routing protocols support
VLSM." Page 623 (only in printing 8 and beyond) - Table F-1 - 2nd row - columns
with "classless rules" and "classful rules" should be reversed. Page 635 (only in printing 8 and beyond) - 1st paragraph - 2nd line, near
the middle: "frame-relay map..." should be "frame-relay interface-dlci...".
Page 637 (only in printing 8 and beyond) - 2nd to last paragraph - 5th
line, near the middle: "...0x2142, bit 7 is set" should state "...bit 6 is
set". 4th Printing
(Entries in this section apply to the 1st - 4th printings) Page 15 - table 1-3 - last row on this page - command should be "enable
password password" - in other words, there is a keyword "password" before
the actual text of the password. Page 16 - table 1-3 - 8th row, 1st column - the "show mac address-table"
command is listed; it should instead be "show mac-address-table". Page 25 - figure 1-3 - the figure shows the MAC addresses in the wrong
place. Server 1 should be 0200.1111.1111, and Payroll Server (aka Server 2)
should be 0200.2222.2222. Page 34 - question 9 - the correct answer (B) lists components of the right
command, but not the entire syntax. The full syntax is "spanning-tree vlan
vlan-number root {primary|secondary}". Page 55 -
