Check Command Syntax
The user interface provides error isolation by using a caret symbol (^
as an indicator. The ^ symbol appears at the point in the command
string where you have entered an incorrect command, keyword, or ar-
gument. The error location indicator and interactive help system allow
you to find and correct syntax errors easily.
In this example, context-sensitive help is used to check the syntax for
setting the clock.
Router# clock ?
set Set the time and date
Router# clock
