* * Slide 1 of 1 Purpose: Emphasize: Suppose you want to set the router clock. If you do not know the command, use context-sensitive help to check the syntax for setting the clock. The help output shows that the set keyword is required. Next, check the syntax for entering the time. Now enter the current time using hours, minutes, and seconds, as shown. The system indicates that you need to provide additional arguments to complete the command. Press Ctrl-P (or Up arrow) to repeat the previous command entry automatically. Then add a space and a question mark (?) to reveal the additional arguments. Now you can complete the command entry. The caret symbol (^) and help response indicate an error. To list the correct syntax, reenter the command up to the point where the error occurred, and then enter a question mark (?). Enter the year using the correct syntax and press Return to execute the command. Note that the user interface provides syntax checking in the form of an error location indicator (^). The caret symbol character appears at the point in the command string where you have entered an incorrect command, keyword, or argument. The error location indicator and interactive help system allow you to find and correct syntax errors easily. * * * * * * * * * * 配置文件的管理 保存文件: 将当前运行的保存到flash 中用于系统初始化。 Switch#copy running-config startup-config Switch#write memory Switch#write 删除文件: 永久性的删除flash 中不需要的文件。 delete flash:config.text 删除VLAN数据库: 永久性的删除flash 中VLAN数据库文件。 delete flash:vlan.dat 查看配置文件内容： Switch#more config.text Switch#show running-config。 Evaluation only.
