1 CCNA R&S: Introduction to Networks Chapter 5: Ethernet
2 Introduction The OSI physical layer provides the means to transport the bits that make up a data link layer frame across the network media. Ethernet is now the predominant LAN technology in the world. Ethernet operates in the data link layer and the physical layer.

5 LLC and MAC Sublayers
6 MAC Sublayer Media Access Control The second responsibility of the MAC sublayer is media access control. Media access control is responsible for the placement of frames on the media and the removal of frames from the media. As its name implies, it controls access to the media. This sublayer communicates directly with the physical layer.
7 Media Access Control The CSMA process is used to first detect if the media is carrying a signal. If a carrier signal on the media from another node is detected, it means that another device is transmitting.
8 MAC Address: Ethernet Identity MAC addressing is added as part of a Layer 2 PDU. An Ethernet MAC address is a 48-bit binary value expressed as 12 hexadecimal digits (4 bits per hexadecimal digit).
9 Frame Processing The MAC address is often referred to as a burned-in address (BIA) The address is encoded into the ROM chip permanently - it cannot be changed by software. It is possible to change the MAC address in software. This is useful when attempting to gain access to a network that filters based on BIA - filtering, or controlling, traffic based on the MAC address is no longer as secure.
10 Activity - MAC and LLC Sublayers
11 Ethernet Encapsulation
12 Ethernet Encapsulation At the data link layer, the frame structure is nearly identical for all speeds of Ethernet. The Ethernet frame structure adds headers and trailers around the Layer 3 PDU to encapsulate the message being sent
13 Ethernet Frame Size Both the Ethernet II and IEEE standards define the minimum frame size as 64 bytes and the maximum as 1518 bytes. This includes all bytes from the Destination MAC Address field through the Frame Check Sequence (FCS) field. The Preamble and Start Frame Delimiter fields are not included when describing the size of a frame. Any frame less than 64 bytes in length is considered a "collision fragment" or "runt frame" and is automatically discarded by receiving stations
14 Introduction to the Ethernet Frame
15 Activity - Ethernet Frame Fields
16 MAC Addresses and Hexadecimal
17 MAC Address Representations
18 Unicast MAC Address A host with IP address (source) requests a web page from the server at IP address For a unicast packet to be sent and received, a destination IP address must be in the IP packet header. A corresponding destination MAC address must also be present in the Ethernet frame header. The IP address and MAC address combine to deliver data to one specific destination host.
19 Broadcast MAC Address As shown in the figure, a broadcast IP address for a network needs a corresponding broadcast MAC address in the Ethernet frame. On Ethernet networks, the broadcast MAC address is 48 ones displayed as hexadecimal FF-FF-FF-FF- FF-FF.
20 Multicast MAC Address As with the unicast and broadcast addresses, the multicast IP address requires a corresponding multicast MAC address to actually deliver frames on a local network. The multicast MAC address is a special value that begins with E in hexadecimal. The remaining portion of the multicast MAC address is created by converting the lower 23 bits of the IP multicast group address into 6 hexadecimal characters.
21 Lab - Viewing Network Device MAC Addresses In this lab, you will complete the following objectives: Part 1: Set Up the Topology and Initialize Devices Part 2: Configure Devices and Verify Connectivity Part 3: Display, Describe, and Analyze Ethernet MAC Addresses
22 MAC and IP Both the physical MAC and logical IP addresses are required for a computer to communicate on a hierarchical network, just like both the name and address of a person are required to send a letter.
23 End-to-End Connectivity, MAC, and IP End devices on an Ethernet network do not accept and process frames based on IP addresses, rather, a frame is accepted and processed based on MAC addresses. On Ethernet networks, MAC addresses are used to identify, at a lower level, the source and destination hosts. How are the IP addresses of the IP packets in a data flow associated with the MAC addresses on each link along the path to the destination? This is done through a process called Address Resolution Protocol (ARP).
24 Lab - Using Wireshark to Examine Ethernet Frames In this lab, you will complete the following objectives: Examine the Header Fields in an Ethernet II Frame Use Wireshark to Capture and Analyze Ethernet Frames
25 Packet Tracer - Identify MAC and IP Addresses This activity is optimized for viewing PDUs. The devices are already configured. You will gather PDU information in simulation mode and answer a series of questions about the data you collect.
26 Introduction to ARP The ARP protocol provides two basic functions: Resolving IPv4 addresses to MAC addresses Maintaining a table of mappings
27 ARP Functions
28 ARP Operation When ARP receives a request to map an IPv4 address to a MAC address, it looks for the cached map in its ARP table. If an entry is not found, the Layer 2 processes notify ARP that it needs a map. The ARP processes then send out an ARP request packet to discover the MAC address of the destination device on the local network. If a device receiving the request has the destination IP address, it responds with an ARP reply. A map is created in the ARP table. Packets for that IPv4 address can now be encapsulated in frames.
29 ARP Role in Remote Communication If the destination IPv4 host is not on the local network, the source node needs to deliver the frame to the router interface that is the gateway or next hop used to reach that destination. The source node will use the MAC address of the gateway as the destination address for frames containing an IPv4 packet addressed to hosts on other networks.
30 Removing Entries from an ARP Table Commands may also be used to manually remove all or some of the entries in the ARP table. After an entry has been removed, the process for sending an ARP request and receiving an ARP reply must occur again to enter the map in the ARP table.

33 Packet Tracer - Examine the ARP Table This activity is optimized for viewing PDUs. The devices are already configured. You will gather PDU information in simulation mode and answer a series of questions about the data you collect.
34 Lab - Observing ARP with the Windows CLI, IOS CLI, and Wireshark In this lab, you will complete the following objectives: Part 1: Build and Configure the Network Part 2: Use the Windows ARP Command Part 3: Use the IOS Show ARP Command Part 4: Use Wireshark to Examine ARP Exchanges
35 How ARP Can Create Problems In some cases, the use of ARP can lead to a potential security risk. ARP spoofing, or ARP poisoning, is a technique used by an attacker to inject the wrong MAC address association into a network by issuing fake ARP replies. An attacker forges the MAC address of a device and then frames can be sent to the wrong destination. Manually configuring static ARP associations is one way to prevent ARP spoofing. Authorized MAC addresses can be configured on some network devices to restrict network access to only those devices listed.
36 Mitigating ARP Problems Switches provide segmentation of a LAN, dividing the LAN into independent collision domains. Each port on a switch represents a separate collision domain and provides the full media bandwidth to the node or nodes connected on that port.
37 Switch Port Fundamentals A Layer 2 LAN switch performs switching and filtering based only on the OSI data link layer (Layer 2) MAC address. A switch is completely transparent to network protocols and user applications. A Layer 2 switch builds a MAC address table that it uses to make forwarding decisions. Layer 2 switches depend on routers to pass data between independent IP subnetworks.
38 Switch MAC Address Table Switches use MAC addresses to direct network communications through their switch fabric to the appropriate port toward the destination node. The switch fabric is the integrated circuits and the accompanying machine programming that allows the data paths through the switch to be controlled. For a switch to know which port to use to transmit a unicast frame, it must first learn which nodes exist on each of its ports.
39 Duplex Settings Half-duplex communication relies on unidirectional data flow where sending and receiving data are not performed at the same time. In full-duplex communication, data flow is bidirectional, so data can be sent and received at the same time. The bidirectional support enhances performance by reducing the wait time between transmissions. Most Ethernet, Fast Ethernet, and Gigabit Ethernet NICs sold today offer fullduplex capability. In full-duplex mode, the collision detect circuit is disabled.
40 Auto-MDIX Switch detects the required cable type for copper Ethernet connections and configures the interfaces accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a copper 10/100/1000 port on the switch, regardless of the type of device on the other end of the connection. The auto-mdix feature is enabled by default on switches running Cisco IOS Release 12.2(18)SE or later. For releases between Cisco IOS Release 12.1(14)EA1 and 12.2(18)SE, the auto- MDIX feature is disabled by default.
41 Frame Forwarding Methods on Cisco Switches In store-and-forward switching, when the switch receives the frame, it stores the data in buffers until the complete frame has been received. During the storage process, the switch analyzes the frame for information about its destination. In this process, the switch also performs an error check using the Cyclic Redundancy Check (CRC) trailer portion of the Ethernet frame.
42 Frame Forwarding Methods on Cisco Switches
43 Cut-Through Switching In cut-through switching, the switch acts upon the data as soon as it is received, even if the transmission is not complete. The switch buffers just enough of the frame to read the destination MAC address so that it can determine to which port to forward the data. The destination MAC address is located in the first 6 bytes of the frame following the preamble
44 Cut-Through Switching Fast-forward switching: offers the lowest level of latency. immediately forwards a packet after reading the destination address. there may be times when packets are relayed with errors. This occurs infrequently, and the destination network adapter discards the faulty packet upon receipt. latency is measured from the first bit received to the first bit transmitted. Fragment-free switching: switch stores the first 64 bytes of the frame before forwarding. compromise between store-and-forward switching and fast-forward switching. most network errors and collisions occur during the first 64 bytes. error check on the first 64 bytes of the frame to ensure that a collision has not occurred Fragment-free switching is a compromise between the high latency and high integrity of store-and-forward switching, and the low latency and reduced integrity of fast-forward switching.
45 Activity - Frame Forwarding Methods
46 Memory Buffering on Switches As discussed, a switch analyzes some or all of a packet before it forwards it to the destination host. An Ethernet switch may use a buffering technique to store frames before forwarding them. Buffering may also be used when the destination port is busy due to congestion and the switch stores the frame until it can be transmitted.
47 Activity - Switch It!
48 Lab - Viewing the Switch MAC Address Table In this lab, you will complete the following objectives: Part 1: Build and Configure the Network Part 2: Examine the Switch MAC Address Table
49 Fixed versus Modular Configuration Fixed configuration switches are fixed in their configuration. What that means is that you cannot add features or options to the switch beyond those that originally came with the switch. The particular model you purchase determines the features and options available. Modular switches offer more flexibility in their configuration. Modular switches typically come with different sized chassis that allow for the installation of different numbers of modular line cards. The line cards actually contain the ports.
50 Fixed versus Modular Configuration
51 Module Options for Cisco Switch Slots Fast Ethernet SFP Modules Gigabit Ethernet SFP Modules 10 Gigabit Ethernet SFP Modules
52 Layer 2 versus Layer 3 Switching Layer 2 LAN switch performs switching and filtering based only on the OSI data link layer (Layer 2) MAC address and depends upon routers to pass data between independent IP subnetworks a Layer 3 switch can also learn which IP addresses are associated with its interfaces. This allows the Layer 3 switch to direct traffic throughout the network based on IP address information as well.
53 Cisco Express Forwarding Cisco Express Forwarding (CEF) CEF decouples the usual strict interdependence between Layer 2 and Layer 3 decision Forwarding IP packets can be slow the constant referencing backand-forth between Layer 2 and Layer 3 constructs The two main components of CEF operation Forwarding Information Base (FIB) Adjacency tables
54 Types of Layer 3 Interfaces Cisco networking devices support a number of distinct types of Layer 3 interfaces. A Layer 3 interface is one that supports forwarding IP packets toward a final destination based on the IP address. The major types of Layer 3 interfaces are: Switch Virtual Interface (SVI) - Logical interface on a switch associated with a virtual local area network (VLAN). Routed Port - Physical port on a Layer 3 switch configured to act as a router port. Layer 3 EtherChannel - Logical interface on a Cisco device associated with a bundle of routed ports.
55 Configuring a Routed Port on a Layer 3 Switch A switch port can be configured to be a Layer 3 routed port and behave like a regular router interface. Specifically, a routed port: Is not associated with a particular VLAN. Can be configured with a Layer 3 routing protocol. Is a Layer 3 interface only and does not support Layer 2 protocol. Configure routed ports by putting the interface into Layer 3 mode with the no switchport interface configuration command. Then assign an IP address to the port. That's it!
56 Packet Tracer - Configure Layer 3 Switches The Network Administrator is replacing the current router and switch with a new Layer 3 switch. As the Network Technician, it is your job to configure the switch and place it into service. You will be working after hours to minimize disruption to the business.
57 Activity - MAC and Choose Please view the video located at the following link: -metcalfe-the-history-of-ethernet Topics discussed include not only where we have come from in Ethernet development, but where we are going with Ethernet technology (a futuristic approach).
58 Summary There are two styles of Ethernet framing: IEEE Ethernet standard and the DIX Ethernet standard which is now referred to Ethernet II. The most significant difference between the two standards is the addition of a Start Frame Delimiter (SFD) and the change of the Type field to a Length field in the Ethernet II is the Ethernet frame format used in TCP/IP networks. As an implementation of the IEEE 802.2/3 standards, the Ethernet frame provides MAC addressing and error checking
