Switch Configuration and Network Setup 3Com 4226T

Lo dejo acá para que no les cueste configurarlos:

Switch Configuration and Network Setup
The 3Com 4226T switch comes with a default IP address which is 169.254.100.100. You will start by changing this IP address to 10.10.10.10 using a Web interface (HTML GUI + HTTP protocol). The 3Com 4226T runs an HTTP Server. You will connect to this HTTP Server from the Windows machine using Internet Explorer browser.
5.1  Explain why the IP address of the Windows machine should be set to 169.254.x.y. (169.254.100.99 for example). Fill in the answer sheet.
5.2  Connect the Windows machine to 3Com 4226T switch using RJ-45 cable and any port on the switch (see figure1).
5.3  Launch Internet Explorer and type in the address field: http://169.254.100.100
5.4  Enter admin as username and leave the password blank. Don’t change the admin password
5.5  Use the Web interface to change the IP address of the switch to 10.10.10.10.
5.6  Change the network parameters of the Windows machine to the following:
IP address: 10.10.10.2
Subnet mask: 255.255.255.0 (24 bits)
5.7  Setup a LAN using the architecture shown in figure 1. Use port 1 for Linux machine and port 2 for Windows machine. (Off course you can use any port of the switch).
5.8  Report the link state described by the LED on each port. Fill in the answer sheet.
5.9  Make sure that machines are well connected by issuing a ping from one machine to the other one.
5.10                      Use IPRoute utility to disable ARP on Linux machine. Fill in the answer sheet with the command issued.
5.11                      Delete ARP cache on Windows machine by issuing:
arp –d * 
Issue a ping from Windows machine to Linux machine. This later should be unreachable. Explain. Fill in the answer sheet.
5.12                      Use IPRoute utility to re-enable ARP on Linux machine.
