Feedback is displaying incorrectly. When a student checks all cells, the feedback is incorrectly indicating a Correct answer.

Task 1: Step 1.

R2 should be a 2621XM router, because the 2811 in PT 4.11 has a default configuration that uses a switch module rather than additional FastEthernet ports.Typo in last bullet: Now add the S1, S2, and S3 distribution layer switches using the 2960-24TT model. Should be S1, S4 and S7.

Chapter Text

In the first sentence of the second paragraph, the glossary link for the word "convergence" refers you to the definition of the word, but the definition relates to a different topic.

Interactive Activity

In question 4, it marks all of the choices as correct even if it is incorrectly put into the wrong tab.

In question 11, if you get something incorrect in the Core Layer tab, everything in the Access Layer tab is marked incorrect. However, if you get something wrong in the Access Layer tab, it is still marked correct.

Chapter Text

In the first paragraph, there is a sentence that states "Only a Layer 3 entity, such as a router, or a virtual LAN (VLAN), can stop a Layer 2 broadcast domain."

Flash Media

In the graphic, the top and middle drag-and-drop boxes are placed next to the arrows. The bottom drag-and-drop box is placed above its arrow. This makes it unclear as to where each answer should go.

Flash Media

The picture shows a console cable connecting an Ethernet port on a labtop to a console port on a switch.

In the graphic, under "Configure Management Interface" 5th row down from the top the text says "Return to Global Configuration mode." and the command says "S1(config-if)#end". That command would take the user back to privileged EXEC mode, not global config mode. The command should be "S1(config-if)#exit"

Under the "Configure Management Interface" button the subnet mask is set to /16 in the "Verify Configuration" button the subnet mask is /24 in the "show running-config" pane. I could not find mention of the proper SM anywhere in the text so beats me which is right.

The blue balloons indicating duplex and speed are oppositely labeled. The S2 balloon is pointing at S1 and vise-versa.

Packet Tracer

In Task 5 Step 3 of the PT, the instructions say "Packet Tracer does not grade the boot system command on switches, so completion remains at 50% at the end of this task." This is NOT true because Packet Tracer does grade the boot system command on switches, just not in this lab. In addition, the directions in this step say to enter the command "S1(config)#boot system flash:/c2960-lanbase-mz.122-25.SEE1.bin"; however this will be graded incorrectly in a later lab with the / after the flash:.

Task 4, Step 3 says to show all dynamically learned MAC addresses, but the command used displays only one specified MAC address.

The command following that statement should be "show mac-address-table dynamic", showing all of the dynamically learned MAC addresses. Afterwards, the question "How many dynamic addresses are there?" should follow. Then, add a line of instruction to look at only the PC1 MAC address, followed by the existing command of "show mac-address-table address <PC1 MAC here>".

The default gateway is listed as 172.17.99.11 and should be listed as 172.17.99.1

Task 3 step 5 tells the student to assign ports fa0/1. fa0/8 and fa0/18 to VLAN 99 but the only commands listed are for interface fa0/1.

Chapter Text

Under the "Layer 3 Forwarding", Step 4 incorrectly identifies PC4 as the destination.




Chapter Text

Under the heading "Which link will be configured as a trunk?", there are repeated paragraphs.

Remove the first paragraph beginning "The link between switches S1 and S2..."

In the "Example" graphic, the arrow from the configuration box is pointing to S2 it should be pointing to S1. Or S1 and S2 need to switch places.

Task 4, Step 10, directions for PC1 address change are incorrect.Task numbers are repeated.Command in Task 4 is incorrect.




Eswitching 4 3 3.7.1.1 English Quiz



In the lab, Task 4 Step 11 states "Change the IP address on PC1 to 192.168.10.22." This is incorrect because PC1 is supposed to be able to ping PC2 in this step and changing PC1's address to 192.168.10.22 will keep the PC1 on vlan 10, preventing it from being able to ping PC2, which is on vlan 20.

Packet Tracer

In the printed lab for the PT Activity, the Port Assignment Table (top of page 2) lists Fa0/1 - 0/5 as being in VLAN 99, but it should be listed as VLAN 56.

Packet Tracer

In the PDF, the addressing table shows PC3's address as 192.168.20.23 when it should be 192.168.30.23.

End of chapter quiz question 9: The correct answer is listed as choice 4 but choice 1 is also correct.

The graphic in the Configure Domain Name output should be 5 BEFORE you add the 3 VLANS, after which it changes to 8.




ESwitching 4 4 4.3.1.4 English Text Text does not match graphic.



In the last paragraph on the page, port Fa0/11 on S2 is assigned to VLAN 20. This is also consistent in the "Configure Access Ports" display, but the topology graphic shows port Fa0/11 on S2 as belonging to VLAN 10. The text and command output should be changed to Fa0/18.

Flash Media

In the graphic under the "Solution" buttons, table is incorrect.

In the "Verify Revision Number" graphic the command output shows output from S3 instead of the verification output of S4.






Under the "Configure New VLANs and Ports" button, the structure of the command in the window is wrong.

Flash Media

The graphics display the VTP version as version 2 and the customer would like it to show version 1 instead.

In the Topology Diagram, the IP addresses of the vlan99 interfaces on the switches are 192.168.x.x, while the ip addresses in the configuration chart for those interfaces are 172.17.x.x.

Task 5 says "…However, because S3 is in transparent mode, VTP pruning must be configured locally on that switch." VTP prunning cannot be enabled on a transparent switch.

Instructor version only, Task 5 says "…However, because S3 is in transparent mode, VTP pruning must be configured locally on that switch." VTP prunning cannot be enabled on a transparent switch.

Flash Media

The graphic used in the PDF is incorrect.

Supplemental Materials

In the interactive course guide in Chapter 4, the How to Teach 13 incorrectly states the command "show vlan status".





The graphic on the page shows that the switches are learning information before they are supposed to learn it. Before the animation begins, S2 shows that it already learned about PC1 before the broadcasts were sent. The actual problem, however, is that the results of the activity are one step ahead of the activity itself. The results are correct, just badly timed.

Flash Media

Both graphics on this page show a D3 switch. The text refers to a D2 switch.

Chapter Text

In the 2nd paragraph, it says: "...the designated port between S3 and S2 is port S0/1 on switch S3." The port is incorrectly identified as a serial.

In Task 1 Step 4, the switchport mode access command and no shutdown command on the fa0/6, fa0/11, and fa0/18 interfaces only turns those interfaces on and into access parts. Later in Task 4 step 6, the interface range command is used in order to assign ranges of ports to VLANs. This results in ports 6 to 10, 12 to 17, and 19 to 24, shutdown and assigned to a vlan when in access mode, but they are still in dynamic auto DTP mode.

Packet Tracer

Wrong default gateway for PCs in activity instructions and grading scheme.

These are the right answers for question 4. The "User Communities" tab should include the answers: Workstation ports required for a department, anticipated department port growth, and intensity of use of a department application server. The "Data Stores and Data Servers" tab should include the answers: data backed up to tape, network attached storage, amount of traffic for a SAN, and amount of server-to-server traffic. Change the grading so that if a student puts the wrong answer in, it is marked incorrect.

In question 11, adjust the grading so that only these answers are marked correct. The "Core Layer" tab should include the answers: 10 Gigabit Ethernet, Layer 3 support, and redundant components. The "Access Layer" tab include the answers: VLANs, PoE, and port security.

Sticky secure MAC addresses have these characteristics:

2nd bullet:If you disable sticky learning by using the no switchport port-security mac-address sticky interface configuration command, the sticky secure MAC addresses remain part of the address table but are removed from the running configuration.

4th bullet:If you save the sticky secure MAC addresses in the configuration file, when the switch restarts or the interface shuts down, the interface does not need to relearn these addresses. If you do not save the sticky secure addresses, they are lost. If sticky learning is disabled, the sticky secure MAC addresses are converted to dynamic secure addresses and are removed from the running configuration.

Change the next full paragraph to read:

The link between switches S1 and S2 becomes a trunk because the F0/1 ports on switches S1 and S2 are configured to ignore all DTP advertisements and come up and stay in trunk port mode. The F0/3 ports on switches S1 and S3 are set to auto, so they negotiate to be in the default state, the access (non-trunk) mode state. This results in an inactive trunk link. When you configure a trunk port to be in trunk port mode, there is no ambiguity about which state the trunk is in-it is always on. It is also easy to remember which state the trunk ports are in-if the port is supposed to be a trunk, trunk mode is on.

In Task 1, the 4th bullet states “Fast Ethernet 0/1 and Fast Ethernet 0/0 and its subinterfaces”. R1 only has Fa0/1 configured. FastEthernet 0/0 should be removed from the bullet.3. In Task 2, Step 1 has a few errors:• The directions do not say to configure hostnames for the switches.• Since the “switchport trunk encapsulation dot1q” command is no longer used on newer switches, this command should be removed from the S1, S2, and S3 configurations.• In the S3 configurations, the int fa0/11 assigns the port to VLAN 11, not VLAN 10. Change the command “switchport access vlan 11” to “switchport access vlan 10”.• In the S3 configurations, the “no shutdown” command for int fa0/4 is spelled incorrectly as “no shutdown”. Correct spelling to “no shutdown”.
