Using the Command-Line Interface 221
Understanding Error Messages
If a command is entered and the system is unable to execute it, an error
message appears. Table 5-2 describes the most common CLI error messages.
If you attempt to execute a command and receive an error message, use the
question mark (?) to help determine the possible keywords or parameters 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.
Table 5-2. CLI Error Messages
Message Text Description
% Invalid input detected
at '^' marker.
Indicates that an incorrect or unavailable
command was entered. The carat (^) shows
where the invalid text is detected. This message
also appears if any of the parameters or values are
not recognized.
Command not found /
Incomplete command.
Use ? to list commands.
Indicates that the required keywords or values
were not entered.
Ambiguous command
Indicates that not enter enough letters were
entered to uniquely identify the command.
Table 5-3. History Buffer Navigation
