1.3.3 Command History

CLI can store the latest executed commands as history commands so that users can
recall and execute them again. By default, CLI can store 10 history commands for each
user. Table 1-6 lists history command-related operations.

Note:
As the Up and Down keys have different meanings in HyperTerminal running on
Windows 9x, these two keys can be used to recall history commands only in
terminals running Windows 3.x or Telnet running in Windows 3.x. You can press
<Ctrl + P> or <Ctrl + N> in Windows 9x to achieve the same purpose.
If you enter and execute the same command successively for multiple times, only
the first command is buffered.

1.3.4 Error Messages

If the command you enter passes the syntax check, it will be successfully executed;
otherwise an error message will appear. Table 1-7 lists the common error messages.
