Negating the Effect of Commands

For many configuration commands, the prefix keyword no can entered to cancel the effect of a command or reset the
configuration to the default value. This guide describes the negation effect for all applicable commands.

Command Completion

If a command is entered and it is not complete, if the command is invalid, or if some parameters of the command are invalid
or missing, the appropriate error message is displayed. This assists in entering the correct command. By pressing the <Tab>
button, an incomplete command is entered. If the characters already entered are not enough for the system to identify a
single matching command, press "?" to display the available commands matching the characters already entered.
Incorrect or incomplete commands are automatically re-entered next to the cursor. If a parameter must be added, the parameter
can be added to the basic command already displayed next to the cursor. The following example indicated that the command
interface ethernet requires the parameter <port-num>.
(config) # interface ethernet
%missing mandatory parameter
(config) # interface ethernet e5
