Command Reference to Check Your Memory
This section includes the most important configuration and EXEC commands covered in this chapter. It might not be necessary to memorize the complete syntax of every command, but you should be able to remember the basic keywords that are needed.
To test your memory of the commands, cover the right side of Table 3-4 with a piece of paper, read the description on the left side, and then see how much of the command you can remember.
