displayed on the screen.
The parsing process is initiated whenever the operator types a command and presses <ENTER>. The command tree is
searched for the command of interest. If the command is not found, the output message indicates where the offending entry
begins. For instance, command node A has the command "show arp brief" but the operator attempts to execute the
command "show arpp brief" then the output message would be $(exec)> show arpp brief^. $%Invalid input detected at
'^' marker. If the operator has given an invalid input parameter in the command, then the message conveys to the operator

of the parameters are not recognized a syntax error message will be displayed.
2.
After the command is successfully parsed and validated, the control of execution goes to the corresponding CLI callback
function.

callback function is only invoked when all the mandatory parameters are provided. For optional parameters, the command
tree extends till the mandatory parameters and the optional parameters make the leaf of the branch. However, the call back
