An intensive hands on IP foundation. The course focuses on all parts of TCP/IP including layers 4 to 7 on end stations as well as layer 3 on routers. The TCP/IP protocols are also studied to enable delegates to be able to troubleshoot TCP/IP using LAN Analysers. Hands on sessions are used to reinforce the theory rather than teach specific manufacturer equipment.
By the end of the course delegates will be able to:
Use ping, traceroute and other tools to diagnose faults on a network.
Configure IP on PCs and routers.
Plan IP addresses and subnets
Analyse IP and TCP packets using an analyser.
What is TCP/IP?
7 layer model, hardware/software layers, network layers, internetworking, protocols, What is IP? What is TCP? The internet, The IAB, RFCs.
Ping and Wireshark
Host configuration, IP addresses, subnet masks, default gateways, ping, hostnames, hosts file Hands on: Testing connectivity with ping. Analysing packets with Wireshark.
Switches and Wireshark
Switches versus hubs, layer 2 forwarding table, flooding, broadcasts. Hands on: Building a switched based network.
telnet and ftp
Switch console port, putty, telnet, file transfer. Hands on: Building a switched based network.

32 bits, dotted decimal, rules, networks, role of subnet masks, simple subnetting, prefix notation. DHCP. Hands on: Addressing and subnetting
IP and the lower layers
ARP, RARP, PPP, other media. Hands on: ARP.
What are routers? What routers do, default gateways, routing and addressing, routing tables, ways to update routing tables. Hands on: Building a simple routed network, traceroute.
