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 5-1lists history command-related operations.

You may use arrow keys to access history commands in Windows 2000/XP/2003 Terminal or Telnet. However, the up-arrow and down-arrow keys are invalid in Windows 9X HyperTerminal, because they are defined in a different way. You can use <Ctrl+P> and <Ctrl+N> instead.

When you enter the same command several times, only one command is saved by the CLI as a history command.

Error Messages

If the command you enter passes the syntax check, it will be successfully executed; otherwise an error message will appear. Table 5-2lists the common error messages.
