Global Values that Affect Capture Filter Actions

Table 7-6 describes the options and settings available that have a global setting. If you set the value in one statement, the value will apply to all other statements.

The post trigger buffer position set in the After trigger, continue to capture packets until the buffer is: %% full field is a global value. For multi-statement filters, if you attempt to set this value after it has already been set in another statement, you will receive a warning message.

	Table 7-6. Capture Filter Global Values
Capture Filter Global		Description
Post Trigger Buffer Position		This defines the percentage of the buffer used to store frames once
		data capture is triggered. For example, assume the post trigger
		buffer position is set to 50% for a module with 32MB of memory.
		After the module is triggered, frames will be captured until 16MB of
		the module memory is full.
Counter 1 through		The value of a custom counter for testing conditions. For example, if
Counter 7		the custom counter is set to 10, and the counter is used as part of a
		condition, the condition will be satisfied when the counter reaches
		10.
		For THGm, seven counters are available.

Frame Types

Four types of frames can be collected and displayed. Refine your selection criteria by selecting only a subset of all frame types. If all boxes are checked, all frame types will be subjected to the other filter criteria you have specified in the Template

Combination box.

The frame type check boxes allow you to select the types of frames you want to cap- ture. For example, if you want to capture only good frames, leave the Good Frames box checked and deselect all other frame types. If you want to capture only error frames, leave all frame types selected with the exception of the Good Frames box.

For other hardware devices other than THGm, the values that define Undersize and Oversize packets are fixed. Fragments/Undersize packets are those with less than 64 bytes and Jabbers/Oversize are those over 1518 bytes. For THGm, the minimum and maximum packet size can be set as described below.
