Filter Example, Capture Conversation

The

Filter Design window in Figure 7-5 shows a template that captures all packets

going to and coming from two IP stations. The conversation is specified by entering

the two IP addresses, using the <-> indicator to capture packets in both directions.

The

Apply Conversation to Template check box is selected to apply the conversation

to the filter template. The filter template is named

Station_7and_8_Conversation.

Note that the filter template must be applied to the filter by pressing the Add button.

Filter templates must appear in the

Template Combination box before they can be

loaded to the hardware device.
