Half Duplex (CSMA/CD)
 Unidirectional data flow
 Higher potential for collision
 Hub connectivity
Full Duplex
 Point-to-point only
 Attached to dedicated switched port
 Requires full-duplex support on both ends
 Collision-free
 Collision detect circuit disabled

Summary
 Switched LANs provide microsegmentation, which means that
each device on a network segment is connected directly to a
switch port and receives its own bandwidth; each device does not
have to contend for bandwidth with any other device on the
network.
 Half-duplex communication in an Ethernet LAN allows data
transmission in only one direction at a time (either sending or
receiving); full-duplex communication allows both sending and
receiving of data simultaneously. Switches provide full-duplex
communication capability.
 Employing a hierarchy of Ethernet connectivity is usually the most
efficient way to provide speed where it will be most effective in a
campus network, implementing Fast Ethernet and Gigabit
Ethernet primarily in workgroup and backbone connections.

Summary (Cont.)
 Loops result when switches connected to the same segment
transmit the same data. The data frames circulate between the
two paths without being removed from the network and may
cause inaccurate data in the MAC address tables.
 The solution to loops is STP, which manages the paths to given
network segments. STP provides path redundancy in an Ethernet
LAN while preventing undesirable active loops in the network.

  • 9. © 2007 Cisco Systems, Inc. All rights reserved. ICND1 v1.0—2-9 Summary  Switched LANs provide microsegmentation, which means that each device on a network segment is connected directly to a switch port and receives its own bandwidth; each device does not have to contend for bandwidth with any other device on the network.  Half-duplex communication in an Ethernet LAN allows data transmission in only one direction at a time (either sending or receiving); full-duplex communication allows both sending and receiving of data simultaneously. Switches provide full-duplex communication capability.  Employing a hierarchy of Ethernet connectivity is usually the most efficient way to provide speed where it will be most effective in a campus network, implementing Fast Ethernet and Gigabit Ethernet primarily in workgroup and backbone connections.
  • 10. © 2007 Cisco Systems, Inc. All rights reserved. ICND1 v1.0—2-10 Summary (Cont.)  Loops result when switches connected to the same segment transmit the same data. The data frames circulate between the two paths without being removed from the network and may cause inaccurate data in the MAC address tables.  The solution to loops is STP, which manages the paths to given network segments. STP provides path redundancy in an Ethernet LAN while preventing undesirable active loops in the network.

Editor's Notes

  1. <number> Lesson Aim <Enter lesson aim here.>
  2. <number> Slide 2 of 2 Emphasize: Full duplex is for point-to-point connections only. A Fast Ethernet full-duplex connection provides a throughput of 200 Mbps (100 Mbps per direction). Note:
  3. <number> Emphasize: “Half” is the default on the Ethernet ports.
  4. <number> Emphasize: The show interfaces command will display the duplex status. FCS errors and late collision errors are discussed in a later slide.
