If more than one item is shown, type more of the keyword characters to distinguish your choice. However, if only
one item is listed, the keyword or abbreviation is valid and you can press tab or the spacebar to advance to the next
keyword.
When typed in place of a parameter, the question mark lists the available options. For example:
(host) #
write ?
erase Erase and start from scratch
file Write to a file in the file system
memory Write to memory
terminal Write to terminal
<cr>
The <cr> indicates that the command can be entered without additional parameters. Any other parameters are
optional.
Command Completion
To make command input easier, you can usually abbreviate each key word in the command. You need type only
enough of each keyword to distinguish it from similar commands. For example:
(host) # configure terminal
could also be entered as:
(host) # con t
Three characters ( con ) represent the shortest abbreviation allowed for configure . Typing only c or co would not work
because there are other commands (like copy ) which also begin with those letters. The configure command is the
only one that begins with con .
As you type, you can press the spacebar or tab to move to the next keyword. The system then attempts to expand
the abbreviation for you. If there is only one command keyword that matches the abbreviation, it is filled in for you
automatically. If the abbreviation is too vague (too few characters), the cursor does not advance and you must type
more characters or use the help feature to list the matching commands.
Deleting Configuration Settings
Use the no command to delete or negate previously-entered configurations or parameters.
l
To view a list of no commands, type no at the enable or config prompt followed by the question mark. For
example:
(host) (config) # no?
l
To delete a configuration, use the no form of a configuration command. For example, the following command
removes a configured user role:
(host) (config) # no user-role <name>
l
To negate a specific configured parameter, use the no parameter within the command. For example, the following
commands delete the DSCP priority map for a priority map configuration:
(host) (config) # priority-map <name>
(host) (config-priority-map) # no dscp priority high
Saving Configuration Changes
Each Dell controller contains two different types of configuration images.
l
The running-config holds the current controller configuration, including all pending changes which have yet to be
saved. To view the running-config, use the following command:
(host) # show running-config
