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

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

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

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

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
