Hands-on Bridges, Switches, Routers

Objectives Prerequisites Who should attend Course Outline Hands-on Sessions

NC-1.0

What you will learn...

If you need to know more about the big, complex enterprise network picture then this is the course for you.

You will learn in three days how to:

  • Understand the operation and deployment of repeaters, bridges, switches, routers and gateways
  • Integrate existing LAN resources into WANs and broadband networks.
  • Build complex internetworksand intranets.
  • Assess the latest internetworking devices to determine which will best suit your LAN needs
  • Understand the internetworking standards which affect LAN/WAN capability

Prerequisites

You should have a good working knowledge and understanding of networking components and LAN/WAN architecture. This is an advanced technical course, designed to guide you through internetworking concepts and all the key issues surrounding bridges, switches and gateways. Basic LAN technology is assumed, otherwise we would recommend either our Hands-on Networking for Rookies, Hands-on Ethernet Networks or Hands-on Token Ring Networks courses.

Who should attend

Anyone who is designing, building or supporting complex LAN/WAN networks. You will probably have a title such as: IT Officer, Network Supervisor, MIS Manager, Technical Support Officer, Systems Integrator, Communications Manager, Systems Engineer, LAN Administrator or Communications Consultant.

Hands-on Sessions


Network configuration

You will install and configure a 4/16Mbps Token Ring and a 10/100Mbps Ethernet network, installing all the network components including the cabling, Network Interface Cards (NICs) and software. UNIX hosts and Novell file servers will also be installed on the network. The performance of the respective networks will be reviewed.

Repeaters

You will install repeaters into the Ethernet and Token Ring networks. The effect of the repeaters will be evaluated.

Transparent bridges

You will configure and install transparent local and remote bridges into the network. You will then use the bridge management software to understand the effect of changing the various bridge parameters. The Spanning Tree Algorithm operation will be investigated.

Source routing bridges

Source routing bridges will be configured and installed on the Token Ring network. The source routing information will be captured on protocol analysers and investigated.

Routers

Routers will be configured and installed on the network. Various protocols such as IPX and IP will be configured on the routers. You will assess the performance of the network and gain a good appreciation of the issues required to install and manage routers in an internetwork.

Switches

Switches will be deployed into the network. VLAN operations will be designed and configured. Layer 2 and layer 3 functionality will be considered. Port based and MAC address VLAN options will be explored.

Protocols

You will investigate the contents of various protocols such as NetBIOS, IPX and TCP/IP. This will reinforce the concepts of protocol stacks and the issues of protocol engineering.
