Basic Troubleshooting
Check cabling and lights Layer 1
Ping the loopback adapter Layer 1-2
Ping, trace route Layer 3
Supplemental Lab or Challenge Activity:
1. Write a ping command that will continuously ping another workstation.
When would you want to do this? Be careful! This is illegal…find out why.
2. Write a ping command to send 50000 bytes packets.
3. Write a ping command to send ten 50000 byte packets.
4. Write a ping command to send 100000 byte packets.
5. Open up multiple DOS windows and send pings to each workstation in your
classroom only at the same time.
6. Go find out what a traffic generator is…how could you use your knowledge of
ping to make a traffic generator?
7. Make a traffic generator using ping commands that will choke out your
network. You will know it is working when they start timing out. Figure out
the optimal ping size that starts choking the network and the maximum size
just before the network chokes. This will be cool to use later to test your
networks.
So What Have I Learned Here?
In this lab you learned the basics of troubleshooting workstation network problems. You
will be using this knowledge as you “Learn by Doing” and practicing for your CCNA
Exam.
