Layer 2 protocols are disabled by default. To enable Layer 2 protocols, use the
no disable
command. For example, in PROTOCOL
SPANNING TREE mode, enter
no disable
to enable Spanning Tree.
Obtaining Help
Obtain a list of keywords and a brief functional description of those keywords at any CLI mode using the
?
or help command:
•
To list the keywords available in the current mode, enter
?
at the prompt or after a keyword.
•
Enter
?
after a command prompt to list all of the available keywords. The output of this command is the same as the
help
command.
Dell#?

•
Enter
?
after a partial keyword lists all of the keywords that begin with the specified letters.
Dell(conf)#cl?

•
Enter
[space]?
after a keyword lists all of the keywords that can follow the specified keyword.

Entering and Editing Commands
Notes for entering commands.
•
The CLI is not case-sensitive.
•
You can enter partial CLI keywords.
•
Enter the minimum number of letters to uniquely identify a command. For example, you cannot enter
cl
as a partial keyword
because both the
clock
and
class-map
commands begin with the letters “cl.” You can enter
clo
, however, as a partial keyword
because only one command begins with those three letters.
•
The TAB key auto-completes keywords in commands. Enter the minimum number of letters to uniquely identify a command.
•
The UP and DOWN arrow keys display previously entered commands (refer to
).
•
The BACKSPACE and DELETE keys erase the previous letter.
•
Key combinations are available to move quickly across the command line. The following table describes these short-cut key
combinations.
