17. Using this command will set the number of commands retained in the history
buffer to 5. If you were to “show history” then you would see the previous 5
commands. This number can range from 0 to 256. (Sounds like a good CCNA
question doesn’t it?).
18. Ok. We are still moving with our prompts. Before we can make any changes to
our router we need to be at the configuration mode prompt.
router#config
Configuring from terminal, memory, or network [terminal]?
router#terminal
router(config)#
Or we can just by-pass that second statement by combining the two statements:
router#config t
router(config)#
19. Let’s change the name of our router. We do this from the privileged mode prompt
using the command “hostname.” Let’s change it to our name.
router(config)#hostname matt
matt(config)#
Notice how the prompt changes immediately to our new hostname.
To leave the configuration mode, just type exit.
matt(config)#exit
matt#
20. It would be a shame if the power were to suddenly get turned off because
everything would be erased. We can save our work to the file that is loaded when
our router starts. Right now our changes are in a file called “runningconfiguration.”
Here we can type in some changes and see if those changes have
the desired effects. If they don’t then we can reverse those changes or even
reboot the router (which would load the “start-configuration” file). Suppose we
like what we have done. Then we just have to copy our running-configuration file
to our start-configuration file. True. It does over write our start-configuration
file, but that is what we want to do. Let’s try it.
matt#copy running-configuration start-configuration
Boy is that a lot to type…just to make it easier you can also type this:
