ITE 1 June 2015

1 June 2015 - IT Essentials Chapter 6

Today you will review OSI and TCP/IP models and wireless standards, watch a video on topologies then focus on completing chapter 6.

Learning Targets:   

You will be able to:

List the layers of the OSI and TCP/IP reference models and the basic functionality of each layer.

Describe the difference between a physical and logical topology and diagram each if asked.

Know the IEEE standards for wireless networking

Intall and configure both wired and wireless network cards and routers

 Configure an OS for networking

1.  complete the OSI quiz on the following sites:


     http://compnetworking.about.com/od/osimodel/l/aa031101a.htm

     http://www.proprofs.com/quiz-school/story.php?title=osi-model_6

2.  Wireless flashcards

https://quizlet.com/Stephanie_Grover/folders/chapter-4-network-access


3.  Physical vs Logical Topology video clip

Review the difference between physical and logical topologies.  I have shared 2 videos presenting the information in 2 different manners.

4.  Pick up with 6.8 computer to network connection completing labs and filling out the packet.

 Do 6.8.2.2 worksheet

Labs: 6.2.8.4 - There are 2 wireless card in the room.  Zack can help locate them - One is installed in his system.  Take turns installing  and uninstalling those cards.  If Zack's system needs a NIC, install a wired card.

Do 6.8.2.9 packet tracer while waiting for one of the wireless cards.

6.8.3  Wireless and Wired Router Configurations

Read and do labs and packet tracer activities.

One of the routers is attached to a system Paul was using.  There are two more routers, new the box, on the solder station.  You may use those, but ensure that they are put back at the end of the day.

Tip:  Check you TCP/IPv4 properties are you using DCHP  or statically assigned?  Is you current address on the same subnet as the router's?

6.8.3.13 requires both a wireless NIC and a router.  you will have to work in teams.

6.8.4 read, fill out packet, complete labs.

8 April 2015

Bring the switches to the horse shoe to complete the assigned Practicals:

Practical 1;  SWITCH AND TWO COMPUTERS

Practical 2:  TWO SWITCHES AND TWO COMPUTERS

You can work with partners.

If you have equipment issues, use packet tracer.

The practicals call for two commands we have not talked about yet -  the logging synchronous and the  no ip domain-lookup commands.  Watch the video clips to learn why they are useful.




Assign the switch IP address to VLAN 1 using the following commands:

Example:

interface Vlan1

description Switch Telnet Connection (Answer may vary)

ip address 192.168.1.1 255.255.255.0

no shutdown
