To move down through an existing configuration command hierarchy, or to create a hierarchy and move down to that level, use the edit configuration mode command, specifying the hierarchy level at which you want to be.
exit
To move up the hierarchy, use the exit configuration mode command. This command is, in effect, the opposite of the edit command.
up
To move up the hierarchy one level at a time, use the up configuration mode command.
top
To move directly to the top level, use the top configuration mode command.
