Flow of Operation

This section captures the flow of operation for the CLI:

1.

The operator logs into the CLI session and enters the User Exec mode. In the User Exec mode

the $(exec)> prompt is 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 an invalid input was detected. The layout of the output is depicted below:

FIGURE 2. Syntax Error Message

After all the mandatory parameters are entered, any additional parameters entered are treated as

optional parameters. If any 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.

3.

For mandatory parameters, the command tree extends till the mandatory parameters make the

leaf of the branch. The 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

function is associated with the node where the mandatory parameters are fetched. The call

back function then takes care of the optional parameters.

4.

Once the control has reached the callback function, the callback function has complete

information about the parameters entered by the operator.

(exec) #show arpp brief

^

%Invalid input detected at ‘^’ marker.

“No” Form of a Command

"No" is a specific form of an existing command and does not represent a new or distinct command.

Only the configuration commands are available in the "no"form. The behavior and the support

details of the “no” form is captured as part of the mapping sheets. The mapping sheets are

contained in the

Appendix A, “IS CLI Mapping

section.

Support for “No” Form

Almost every configuration command has a “no” form. In general, use the no form to reverse the

action of a command or reset a value back to the default. For example, the “no shutdown interface’

configuration command reverses the shutdown of an interface. Use the command without the

keyword no to re-enable a disabled feature or to enable a feature that is disabled by default.

Behavior of Command Help ("?")

The "no"form is treated as a specific form of an existing command and does not represent a new or

distinct command. This implies that the behavior of the "?" and help text is the same for the “no”

form:

•

The help message is the same for all forms of the command. The help string may be

augmented with details about the "no" form behavior.

•

For the (no config interface?) and (no config inte?) cases of the "?", the options displayed are

identical to the case when the "no" token is not specified.
