Sybex CCNA Chapter 2: Ethernet Networking and Data Encapsulation Instructor & Todd Lammle

Chapter 2 Objectives The CCNA Topics Covered in this chapter include: –Use the OSI and TCP/IP models and their associated protocols to explain how data flows in a network –Select the appropriate media, cables, ports, and connectors to connect switches to other network devices and hosts –Explain the technology and media access control method for Ethernet networks –Explain network segmentation and basic traffic management concepts –Select the appropriate media, cables, ports, and connectors to connect routers to other network devices and hosts 2

Ethernet Networking Ethernet is a contention media access method that allows all hosts on a network to share the same bandwidth of a link. Ethernet is popular because it’s readily scalable, meaning that it’s comparatively easy to integrate new technologies, such as Fast Ethernet and Gigabit Ethernet, into an existing network infrastructure. It’s also relatively simple to implement in the first place, and with it, troubleshooting is reasonably straightforward. 3

Ethernet Collision Detection 4 CSMA/CD

Half and Full Duplex 5 Half-duplex Ethernet is defined in the original Ethernet; Cisco says it uses only one wire pair with a digital signal running in both directions on the wire. But full-duplex Ethernet uses two pairs of wires instead of one wire pair like half duplex. And full duplex uses a point-to-point connection between the transmitter of the transmitting device and the receiver of the receiving device. Full-duplex Ethernet can be used in three situations: With a connection from a switch to a host With a connection from a switch to a switch With a connection from a host to a host using a crossover cable

Ethernet Addressing 6 The MAC, or hardware, address is a 48-bit (6-byte) address written in a hexadecimal format.

Binary Addressing 7 Binary to Decimal Memorization Chart B INARY D ECIMAL Conversion Example

Ethernet at the Physical Layer 8 The IEEE and original Ethernet Physical layer specifications.

Ethernet Cabling 9 Ethernet cabling is an important discussion, especially if you are planning on taking the Cisco exams. Three types of Ethernet cables are available: Straight-through cable Crossover cable Rolled cable We will look at each in the following sections.

Straight Through 10 The straight-through cable is used to connect Host to switch or hub Router to switch or hub

Crossover Cable 11 The crossover cable can be used to connect Switch to switch Hub to hub Host to host Hub to switch Router direct to host

Rolled Cable 12 Although rolled cable isn’t used to connect any Ethernet connections together, you can use a rolled Ethernet cable to connect a host to a router console serial communication (com) port.

Using Hyper Terminal 13 Notice the settings for Hyper Terminal

What type of cable is used? 14

What type of cable is used for each connection? 15

Data Encapsulation When a host transmits data across a network to another device, the data goes through encapsulation: It is wrapped with protocol information at each layer of the OSI model. Each layer communicates only with its peer layer on the receiving device. 16

Data Encapsulation 17

PDU 18

Port Numbers 19 The Transport layer uses port numbers to define both the virtual circuit and the upper-layer process.

Cisco’s Three-Layer Model 20 The following are the three layers and their typical functions: The core layer: backbone The distribution layer: routing The access layer: switching
