1 Ver AB Terms Host: The computer to be tested Gateway: The router connected to that part of the network PDU: Protocol Data Unit Perform Network Fault Isolation Techniques

2 Ver AB Commands Ipconfig: Shows the IP address of the host Ipconfig /all: Show additional information of the host –IP Addressing: Static - Assigned by the administrator Dynamic - Assigned by a DHCP Server Arp: Address Resolution Protocol, maps IP Address to MAC Address Perform Network Fault Isolation Techniques

3 Ver AB Commands Ping: Used to test whether a particular host is reachable across an IP network –Ping : tests the NIC only (Local Loop Back test) –Ping (ip address of host): tests connection to the switch (Loopback test) –Ping (ip address of another host): tests connection between two nodes Perform Network Fault Isolation Techniques

14 Ver IT AA-1 14 StepActionProcedure Normal Indication If Indication is Abnormal If Indication is Normal 1 Check IP Address Click on the computer to be checked Select ‘Desktop’ Select ‘Command Prompt’ At the command prompt type: ‘ipconfig’ IP Address matches the IP address shown on the configuration Chart 3 Proceed to Step 2 after closing command prompt screen Proceed to Step 3 2 Correct IP Address On desktop screen Select ‘IP Config’ Enter correct Static IP Address or select DHCP as required on configuration chart 1 on the answer sheet Repeat Step 1 3Perform local loopback test At the command prompt type: ‘ping ’ Good pingReinstall or replace the NIC, repeat step 1 Proceed to Step 4 Chart 1 - Packet Tracer Checkout and Troubleshooting

15 Ver IT AA-1 15 Chart 1 - Packet Tracer Checkout and Troubleshooting StepActionProcedure Normal Indication If Indication is Abnormal If Indication is Normal 4 Perform loopback test At the command prompt ping the IP address of the host to be checked as indicated in step 1 Good Ping Proceed to Step 5 Proceed to Step 8 5 Check the NIC configuration Select ‘Config’ tab Select ‘Fast Ethernet’ button Verify configuration against fig x.1 or x.2 Configuration correct Make required correction to configuration and repeat step 4 Proceed to Step 6 after closing host configuration screen 6Check switch port configuration Select the switch to be checked Select ‘Config’ tab Select the port to be checked according to the configuration chart Verify configuration against fig x.3 Configuration correct Make required correction to configuration and repeat Step 4 after closing configuration screen Proceed to Step 7

16 Ver IT AA-1 16 After reading the scenario, then close or move the PT Activity screen to the side

17 Ver IT AA-1 17 Clicking on a computer will bring up the physical view screen, then select the Desktop Tab

18 Ver IT AA-1 18 On the desktop screen select Command Prompt

19 Ver IT AA-1 19

20 Ver IT AA-1 20 Step 1 To check the IP configuration, type ipconfig, then hit enter. Check information against Chart 1 in the handout

21 Ver IT AA-1 21 Step 2 (if required) To correct the IP configuration, close the command prompt screen and select IP Configuration

22 Ver IT AA-1 22

23 Ver IT AA-1 23 Step 3 If IP configuration is correct, then ping to test the NIC

24 Ver IT AA-1 24 Step 4 Ping the IP address of the computer to check connection to the switch

25 Ver IT AA-1 25 Step 5 (if required) Select the Config tab and FastEthernet tab and compare the setting with the figures in the handout

26 Ver IT AA-1 26 Step 6 (if required) Select the switch to be checked, then select Config tab and the port to be checked. This information is found on the Configuration Chart in the handout Check against trhe figure in the handout

27 Ver IT AA-1 27 Step 7 To remove a cable select the X, then select the cable to be removed

28 Ver IT AA-1 28 Step 7 To install a cable select the buttons identified below

29 Ver IT AA-1 29 Step 8 Ping the IP address of the gateway to check connection to the router

35 Ver IT AA-1 35 Network Switches

36 Ver IT AA-1 36 Network Routers (Default Gateways)

37 Ver IT AA-1 37 StepActionProcedure Normal Indication If Indication is Normal If Indication is Abnormal 1 Check IP Configuration  Double click on the computer to be checked  At the command prompt type “ipconfig”, the press enter IP Configuration matches Configuration Chart 1 Proceed to Step 3 Proceed to Step 2 2 Correct IP Address  Right click on the host icon  Select ‘Configs’  Enter correct IP information as shown on RouterSim Configuration chart. Click OK, and Close. Repeat Step 1 3Perform loopback test  At the command prompt ping the IP address of the host to be checked Good PingProceed to Step 4 Repeat Step 1

38 Ver IT AA-1 38 StepActionProcedure Normal Indication If Indication is Normal If Indication is Abnormal 4 Test connectivity to the gateway  From the host machine command prompt screen, ping the IP address of the gateway router Good pingTest complete Proceed to Step 5 5Check cables  Visually check that the cable in installed and connected to the correct location (Chart 5) Cable properly connected Go to Step 1 and repeat the lab. To remove cable go to Step 6 To Install a cable go to step 7 6Remove a cable  Right click the device, then right click on the port of the cable to be removed. Select ‘Yes’ at the Remove pop-up Proceed to Step 7 for installation of a cable

39 Ver IT AA-1 39 StepActionProcedure Normal Indication If Indication is Normal If Indication is Abnormal 7Install a cable  Refer to Chart 5 for the correct configuration. Right click on the device to be connected, then right click on the port cable is to be connected to.  Right click the device and port for the opposite end of the cable. Repeat Step 4

40 Ver IT AA-1 40 Ex: Fault; MTL-2 cannot access the network

41 Ver IT AA-1 41 Double left click on MTL-2 to enter Console screen

42 Ver IT AA-1 42 Using IPCONFIG to check IP Configuration

43 Ver IT AA-1 43 HostIP AddressSubnet MaskGatewayConnected to MTL Connors Manor Port 8 MTL Connors Manor Port 4 MTL Connors Manor Port 5 Rm Dolan hall Port 1 Rm Dolan Hall Port 8 Rm Wolfe Hall Port 2 Rm Wolfe Hall Port 8 Help Desk Network Support Port 1 Compare IP Configuration to the IP configuration chart All hosts use static IP addresses

44 Ver IT AA-1 44 To correct IP configuration, Right click the computer (MTL-2) to get Host screen, then select Configs to enter configuration screen

45 Ver IT AA-1 45 IP Configuration screen

46 Ver IT AA-1 46 PING command to test local loopback

47 Ver IT AA-1 47 Perform Network Fault Isolation Network Flow Control “Ping” command –A failed “ping” command

48 Ver IT AA-1 48 PING command to default gateway

49 Ver IT AA-1 49 If ping to gateway is bad, then ping another host on same switch. Good ping indicates faulty cable between switch and router. Bad ping indicates bad cable between host and switch

50 Ver IT AA-1 50 Right click on a switch to view connections To remove a connection, left click on the port to be disconnected

51 Ver IT AA-1 51 Right click on router to see connections

52 Ver IT AA-1 52 When done DO NOT save changes
