Addressing problems are the most common
problems that occur on IP networks. The following three commands 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 testing
mechanism.
- telnet
verifies the application layer software between source and
destination. This is the most complete test mechanism available.
- traceroute
allows the location of failures in the path from the source to
the destination. Trace uses Time to Live values to generate messages
from each router along the path.
