To examine this the IOS offers an "extended" mode of the ping command. This mode is entered by typing ping in privileged EXEC mode, at the CLI prompt without a destination IP address. A series of prompts are then presented as shown in this example. Pressing Enter accepts the indicated default values.
- Code: Select all
Router#ping
Protocol [ip]:
Target IP address:10.0.0.1
Repeat count [5]:
Datagram size [100]:
Timeout in seconds [2]:5
Extended commands [n]: n
Entering a longer timeout period than the default allows for possible latency issues to be detected. If the ping test is successful with a longer value, a connection exists between the hosts, but latency may be an issue on the network.
Note that entering "y" to the "Extended commands" prompt provides more options that are useful in troubleshooting - you will explore these options in the Lab and Packet Tracer activities.
