Switching

Router is a special type of computer. It has the same basic components as a standard desktop computer, and equipped with memories (Ram & Rom) and various input / output interfaces, a bus system, as well as a processor (CPU) .

The switches can theoretically support up to 250 VLANs managed simultaneously and It is he who distributes the network in lan, Use in layer 3 and 2 of the osi model, this is a table of MAC addresses.

the router and the switch are alike used to distribute the connection between several devices.


Plan: 

A- LAN (Local Area Network)

      
      - History and function of half-duplex Ethernet shared media

      - Define the principle of collision in the context of an Ethernet network

      - Define segmentation

      - LAN segmentation using bridges:

      - LAN segmentation using routers

      - LAN segmentation using switches

      - Basic operation of a switch

      - Switching of layers 2 and 3

      - Symmetrical and asymmetrical switching

      - Buffering

      - Operation of a switch:

      - Frame transmission modes

      - Filtering of frames by switches and bridges


Switching Concepts

      - The four major objectives of LAN network design

      - List the key considerations of LAN network design

      - The different stages of a methodical LAN network design

      - Functions of an access layer switch

      - Functions of a distribution layer switch

      - Functions of a core network layer switch

      - Advantages of hierarchical network

      - Principles of a hierarchical network model

      - Functionality of an SFF Connectors switch

      - Functionality of a performance switch)


B- Switch configuration


Main elements of Ethernet / 802.3 networks


CSMA-CD:

       - Switch start:

       - Information display after initial switch-on

       - Help overview of the switch command line interface

       - Switch control modes

       - Configure the hostname and passwords on the Switch

       - Configure Layer 3 access to the switch

       - Types of secure MAC addresses

       - Verification of port security

       - Orders

       - 1900/2950 password recovery procedure


Virtual LANs:

       - VLAN

       - Advantages of a virtual local network

       - Types of VLANs

       - Create and name two VLANs

       - Create the aggregation

       - Assign ports to VLAN 2



VTP PROTOCOL (Virtual Trunking Protocol):

        - VTP

        - VTP components

        - VTP configuration:

             Step 1: Configure the VTP server

             Step 2: Configure VTP Clients

             Step 3: connect to the vtp server


STP Spanning Tree Protocol:

         - Redundancy on the links

         - Other type of redundancy

         - PLEASE

         - Configuration

         - Calculation of path costs

         - The state of the ports on STP

         - Spanning Tree Protocol
