4.2.6 IP address-related problems are the most common problems that occur on IP networks. This page will describe three commands that are used to perform address-related troubleshooting:
- ping uses the ICMP protocol to verify the hardware connection and the IP address of the network layer. This is a basic test mechanism.
- telnet verifies the application layer software between a source and a destination. This is the most complete test mechanism available.
- traceroute locates failures in a path from a source to a destination. This command uses Time to Live values to generate messages from each router along a path.
The Lab Activity will require students to configure devices in a WAN and then troubleshoot IP address issues.
This page concludes this lesson. The next page will summarize the main points from this module.
