Understanding Error Messages

If you enter a command and the system is unable to execute it, an error
message appears. Table 5-2 describes the most common CLI error messages.

that are available.

Recalling Commands from the History Buffer

Every time a command is entered in the CLI, it is recorded in an internally
managed Command History buffer. By default, the history buffer is enabled
and stores the last 10 commands entered. These commands can be recalled,
reviewed, modified, and reissued. This buffer is not preserved after switch
resets.
Description
Indicates that you entered an incorrect or
unavailable command. The carat (^) shows
where the invalid text is detected. This message
also appears if any of the parameters or values are
not recognized.
Indicates that you did not enter the required
keywords or values.
Indicates that you did not enter enough letters to
uniquely identify the command.
