Networking Lab Objectives

• Familiarize the student with the basic components
  of a network (LAN and WAN).
• Provide the student with an overview of network
  interface card, switch, and router configuration.
  
• Introduce the student to the roles of the medium,
  network interface card, switch and router within
  a network (LAN and WAN).
• Introduce the student to the OSI Reference Model
  and data encapsulation.
• Familiarize the student with the basic network
  communication. Explain how a data packet
  (logically grouped unit of information) moves
  between computer systems.

5

  Classroom, Room NC 2407
• Must check in with Raytheon Lab in Room NC-2608
  to sign out key to Telecom Lab
• Labs should be completed in groups
• Ask questions
• Make suggestions for improvement

6
Lab 2 IP Addresses

• Objectives
• This lab will focus on your ability to accomplish
  the following tasks
• Name the five different classes of IP addresses
• Describe the characteristics and use of the
  different IP address classes
• Identify the class of an IP address based on the
  network number
• Determine which part (octets) of an IP address is
  the network ID and which part is the host ID
• Identify valid and invalid IP host addresses
  based on the rules of IP addressing
• Define the range of addresses and default subnet
  mask for each class

7
Lab 2 IP Addresses

• Background
• This lab will help you develop an understanding
  of IP addresses and how TCP/IP networks operate.
  IP addresses are used to uniquely identify
  individual TCP/IP networks and hosts (computers
  and printers) on networks in order for devices to
  communicate. Workstations and servers on a TCP/IP
  network are called "HOSTS" and each will have a
  unique IP address which is referred to as its
  "HOST" address. TCP/IP is the most widely used
  protocol in the world. The Internet or World Wide
  Web uses only IP addressing. In order for a host
  to access the Internet, it must have an IP
  address.

8
Lab 3 Subnetting

• Objectives
• This lab will focus on Class C subnet masks and
  your ability to accomplish the following tasks
• Cite some reasons why a subnet mask would be
  needed
• Distinguish between a Default Subnet Mask and a
  Custom Subnet Mask
• Determine the subnets available with a particular
  IP network address and subnet mask
• Given a network address and the requirements for
  this networking lab how many subnets and hosts,
  be able to determine what subnet mask should be
  used
• Given a network address and a subnet mask, be
  able to determine the number of subnets and host
  per subnet that can be created as well as useable
  subnets and useable number of hosts
• Identify valid and invalid IP host address based
  on a given a Network number and subnet mask

9
Lab 3 Subnetting

• Background
• This lab will help you understand the basics of
  IP subnet masks and their use with TCP/IP
  networks. The subnet mask can be used to split up
  an existing network into "subnetworks" or
  "subnets".
• This may be done to
• Reduce the size of the broadcast domains (create
  smaller networks with less traffic)
• To allow LANs in different geographical locations
  to communicate
• For security reasons to separate one LAN from
  another.

10
Lab 4 Protocol Analyzer

• Objectives
• This lab will focus on your ability to accomplish
  the following tasks
• Describe the characteristics of a protocol
  analyzer.
• Use the PING command to initiate network traffic
  and analyze the associated packets.
• Identify the MAC address associated with a
  routers interface port.
• Determine the number of packets associated with a
  PING command.
• Determine the size of each packet.
• Determine the protocol associated with each
  packet.

11
Lab 4 Protocol Analyzer

• Background
• EtherPeek NX, with NetSense Real-Time Expert
  Technology, has been carefully designed to assist
  IT Professionals in analyzing and diagnosing
  increasingly large and diverse volumes of network
  data, providing precise, contemporary analysis of
  the problems facing today's networks. NX Expert
  Analysis features track dozens of separate
  aspects of network performance, showing the
  source of problems at the packet level. The
  Expert View provides expert analysis of latency,
  throughput, and dozens of network problems in a
  conversation-centered view of traffic. The Peer
  Map creates a map of conversations, showing
  traffic volume and protocol information for each
  pair of nodes.

Lab 5 Router Command Line Interface

• Objectives
• Login to a router in both user and privileged
  modes.
• Use several basic router commands to determine
  how the router is configured. 
• Become familiar with the router HELP facility. 
• Use the command history and editing features. 
• Logout of router.

13
Lab 5 Router Command Line Interface

• Background
• This lab will introduce the Cisco Internetwork
  Operating System (IOS) command line user
  interface. You will login to the router and use
  different levels of access to enter commands in
  "User Mode" and "Privileged Mode". You will
  become familiar with the commands available in
  each mode (User or Privileged) and use the router
  HELP facility, history and editing features. The
  IOS command interface is the most common method
  of configuring a Cisco router. You will see many
  commands available, especially in privileged
  mode.

14
Lab 6 Configuring the Router

• Objectives
• Use the Interface Configuration Mode to configure
  interfaces. 
• Configure IP address assignments for router
  interfaces. 
• Configure subnet mask assignments for router
  interfaces. 
• Copy the running configuration to the backup
  configuration.

15
Lab 6 Configuring the Router

• Background
• In this lab you will use the router's interface
  configuration mode to configure an IP address and
  subnet mask for each router interface. You will
  verify that layer 3 connectivity is ok by using
  the ping command. The show running-config command
  will help to make sure the changes you have made
  are what was intended. You will then save the
  running configuration to the backup
  configuration.

16
Network Communication

• The information that travels on a network is
  referred to as data, packet, or data packet.
• A data packet is a logically grouped unit of
  information that moves between computer systems.
• It includes the source information along with
  other elements that are necessary in order to
  make communication possible and reliable with the
  destination device.
• The source address in a packet specifies the
  identity of the computer that sends the packet.
  The destination address specifies the identity of
  the computer that finally receives the packet.
