CISCO Packet Tracer

BASIC NETWORK CONNECTIONS Now we are able to navigate the CLI with some degree, and have done some initial CONFIGURATION, we will now look at the simplest way this SWITCH can facilitate Network communication, to do this we will add two further HOSTS to the Network It would be possible to load the previous SAVED TASK and add two computers, but for practice sake, and to ensure that the labelling of the DEVICES is the same within your CISCO PACKET TRACER, and that of this TASK, we shall start anew The first thing we need do is add a HOST, So we click on END DEVICES, GENERIC HOST and drag that onto our WORKSPACE Next for the 2960 SWITCH we select NETWORK DEVICES, SWITCHES, 2960 SWITCH and drag that onto our WORKSPACE To connect them together, we select CONNECTIONS, then ROLL-OVER CABLE To connect the devices together we click on the HOST and select the SERIAL or RS232 PORT This is then connected to the CONSOLE PORT of the SWITCH Now to add two further HOSTS END DEVICES, then drag two HOSTS onto the WORKSPACE As in reality these two HOSTS will need connecting to the SWITCH, so once again we select CONNECTIONS, and this time we shall use the COPPER STRAIGHT-THROUGH CABLE This will be connected to the FASTETHERNER0/1 of the SWITCH, then to the FASTETHERNET0 of the first HOST Shortly after connecting the CABLE, you will notice that the SWITCH end of the CABLE is accompanied by an ORANGE DOT as shown here After a short time, this will turn GREEN, in our example we have speeded this up. This is PACKET TRACERS way of indicating that the PORT is starting up, by default the PORTS are switched off until they are needed. This mimics the LINK STATUS LIGHTS of a PHYSICAL SWITCH. Now to repeat this for the other HOST, COPPER STRAIGHT-THROUGH CABLE, to the FASTERNETHNET0/2 of the SWITCH to the FASTETHERNET of PC2 Before we can carry on we should wait until the ORANGE LIGHT turns to GREEN to indicate connectivity Now let’s check on the TERMINAL through PC0 So we click on PC0, DESKTOP then TERMINAL Notice here you will see that several messages have appeared, to indicate that some of the PORTS on the SWITCH have change their status. We shall MINIMISE the TERMINAL rather than close it, as we shall monitor the activity of the SWITCH during the rest of this TASK. Now to assign some IP ADDRESSES to our HOSTS So we click on PC1, CONFIG TAB then on the FASTETHERNET0 ADAPTER Here we can enter our IP ADDRESS for this HOST, 10.0.0.1 and SUBNET MASK of 255.0.0.0 We shall close this and repeat it for PC2, CONFIG TAB then FASTETHERNET0 ADAPTER, and this time we shall enter for the IP ADDRESS, 10.0.0.2 with a SUBNET MASK of also 255.0.0.0 Now we have the workings of a small Network between PC1 and PC2 We can prove the connectivity between these HOST running the PING COMMAND Clicking on DESKTOP, COMMAND PROMPT then first using the ipconfig COMMAND that will check that the IP ADDRESS has been correctly assigned Then the ping 10.0.0.1 to check successful connectivity, and as we can see it is. Let’s close this and check connectivity from PC1 to PC2, so we click on PC1, DESKTOP TAB, COMMAND PROMPT Check that the IP ADDRESS has been successfully assigned using the COMMAND ipconfig Then for connectivity using ping 10.0.0.2 And as we can see it has been established once again. Although our Network is very small and basic, we now have a LAB from which we can test some of the functions of the SWITCH and see exactly the effects they will have. Close this WINDOW and return to the PC0 TERMINAL and let’s see what, if anything has changed You will be given a long list with information about the various interfaces, notice FASTETHERNET0/1 is UP. Use the SPACE KEY and notice that FASTETHERNET0/2 is also UP. And if we continue using the SPACE KEY we shall find all other FASTETHERNET POSTS are DOWN or DISABLED To view the INTERFACE STATUS we need to be in the ENABLE MODE so we use the COMMAND enable And to view the INTERFACE STATUS we use the show interfaces COMMAND You will be given a long list with information about the various interfaces, notice FASTETHERNET0/1 is UP
