Dell PowerConnect 8024 User Manual

Using the Command-Line Interface 115
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.
If you attempt to execute a command and receive an error message, use the
question mark (?) to help you 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.
