Type “help” to display a list of commands that includes a brief summary of each command’s purpose.
The list includes all commands available at the current privilege level. That is, at the Operator level, executing
help displays the Help summaries only for Operator-Level commands. At the Manager level, executing help
displays the Help summaries for both the Operator and Manager levels, and so on.
Type a command string followed by “help” to display detailed information about how to use an individual command. Use the following syntax:
<command-string> help
Help is displayed for any command that is available at the current privilege level. An “Invalid input” message is displayed if you try to list the help for an individual command from a privilege level that does not include that command.
The following example shows the result of typing “help” at the Operator privilege level. The Operator-Level commands are listed with their purposes.
The following example shows Help for the
interface command at the Global Configuration privilege level:
Note that trying to list the help for an individual command from a privilege level that does not include that command results in an error message. For example, trying to list the help for the
interface command while at the global configuration level produces this result:
switch# speed-duplex help
Invalid input: speed-duplex
