Describe the command history feature.
What will be an ideal response?
The command history allows you to retrieve previously typed commands. You can see up to 10 previously typed commands by typing show history from either the user EXEC or privileged EXEC mode. You can use the up arrow (or press Ctrl+P) to retrieve previous commands. The down arrow (or Ctrl+N) will retrieve recent commands, assuming that you are viewing previous commands. If you type part of a command, you can press the Tab key to complete the command.
To modify the number of commands stored by the router, you can use the terminal command. You can set the history buffer to zero so that it will not store commands, or you can set it to store up to 256 previous commands. For example, to decrease the number of commands stored from the default of 10 to three, you would type terminal history size 3 at the enable prompt.
