A repeater recreates the incoming signal and re-transmits it without noiseor distortion that may have effected the signal as it was transmitted downthe cable.

Repeaters were available on legacy Ethernet to increase the overall length

of the network and allow additional nodes to be added.

Layer 2Data Link802.3EthernetLocal Area Network (LAN)

The Data Link layer is divided into two sub layers:

The Media Access Control(MAC) sub-layer and the Logical Link Control

(LLC) sub-layer.

MAC (802.3) lower sub-layer controls how a device on the network gains access to the

data and permission to transmit it. Ethernet Media Access: CSMA/CD

LLC (802.2) upper sub-layer controls frame synchronization, flow control, and acts as

an interface between the MAC sub-layer and the network layer.

Layer 2 LAN and WAN Examples:

802.3, 802.5, Frame Relay, ATM, ISDN, MPLS (service providers) Layer 2 Protocol Examples:

ARPAddress Resolution Protocol

Layer 2Data LinkHardware Addressing

All devices on Ethernet communicate using the Ethernet address for the device. This

address is sometimes referred to as the hardware, burned-in or MAC address

(MAC stands for Media Access Controller).

The hardware address is a unique (in the world) 6-byteaddress that is embedded in

the circuitry of every device that sits on an Ethernet network. First 3-bytesidentify aspecific vendor.

Every vendor of Ethernet products obtains their own unique address range

Allen-Bradleys is 00:00:BC:XX:XX:XX and 00:1D:9C:XX:XX:XX

Example - 00:00:BC:03:52:A9

Note that each digit of the MAC address is a hex number (range 0-F)

Layer 2Data LinkLAN Transmission Methods

Unicast

A method by which a frame is sent to a single destination.

Multicast

A technique that allows copies of a single frame to be passed to a

selected subset of possible destinations. Example: 01-00-0C-CC-CC-CC (Cisco Discovery ProtocolCDP)

Broadcast

A frame delivery system that delivers a given frame to all hosts on theLAN.

FF:FF:FF:FF:FF:FF


31/72


Layer 2 - Data LinkBridging

A bridge is a device that isolates traffic between segments by selectively forwarding

frames to their proper destination. It is transparent to the network and protocol

independent.

Similar to the repeater, the bridge isnt used much any more, but more advanced

devices which perform the bridging function are commonly used.

Forwards frames based on the MAC address and a forwarding

table

Learns a stations location by examining source address

Sends out all ports when destination address is

broadcast, multicast, or unknown address Forwards when destination is located on different

interface

segmentation (VLAN tag), security, QoS, resiliency, etc.

Gateways and Routers use the network portion of IP addresses to

identify where networks are.

Switch/route packets by IP Address.

Stratix 8300Layer 2 and Layer 3 switching.

A table is kept that tells the device which port a message should be

transmitted out in order to get the message to the proper network. If the particular network is not directly attached to that device, it will

simply

forward the message to the next

gateway or router in the path for

further routing.
