4.2.2 Creating and Removing a Custom Stack
To create a custom stack:
1. Choose Protocol Stack from the
Options menu on the Control
window or click the Protocol Stack
icon
on the
Frame Display
toolbar.
2. Select Build Your Own from the
list and click Next .
3. The system displays an information
screen that may help you decide if
you need to define your own
custom stack. Defining a custom
stack means that the analyzer uses
the stack for every frame. Frames
that do not conform to the stack
are decoded incorrectly. Click
Next to continue.
Select Protocols
1. Select a protocol from the list on
the left.
2. Click the right arrow button to
move it to the
Protocol Decode
Stack
box on the right, or double-
click the protocol to move it to the
right.
3. To remove a protocol from the
stack, double-click it or select it
and click the left arrow button.
4. If you need to change the order of the protocols in the stack, select the protocol you want to move,
and click on the Move Up and Move Down buttons until the protocol is in the correct position.
5. The lowest layer protocol is at the top of the list, with higher layer protocols listed underneath.
Auto-traversal (Have the analyzer Determine Higher Layers)
If you need to define just a few layers of the protocol stack, and the remaining layers can be determined
based on the lower layers:
1. Click the All additional stack layers can be determined automatically button.
2. If your protocol stack is complete and there are no additional layers, click the There are no
additional stack layers button.
3. If you select this option, the analyzer uses the stack you defined for every frame. Frames that do use
this stack are decoded incorrectly.
