4.3.1.13.1.5 Defining Node and Conversation Filters
There are two steps to using Node and Conversation display filter. Define the filter conditions, and then apply
the filter to the data set. The analyzer combines both filter definition and application in one dialog.
1. Click the
Display Filters
icon on the
Frame Display
window or select
Apply/Modify
Display Filters…
from the filter menu to open the
Set Condition
dialog box.
2. From the Select each frame combo box choose frames with the conversation as the initial
condition.
3. Select an address type—IP, MAC, TCP/UDB—from the Type combo box (The address type selection
populates both Address combo boxes with node address in the data set that match the type selection).
4. Select a node address from the first
Address
combo box.
5. Choose a direction arrow from the direction box . The left arrow filters on all frames
where the top node address is the destination, the right arrow filters on all frames
where the top node address is the source, and the double arrow filters on all
frames where the top node address is either the source or the destination.
6. If you want to filter on just one node address, skip step 7 and continue with step 8.
7. If you want to filter on traffic going between two address nodes (i.e. a conversation), select a node
address from the second Address combo box..
8. Click OK . The Set Condition dialog box closes and the analyzer applies the filter.
When a display filter is applied, a description of the filter appears to the right of the toolbar in the

4.3.1.13.1.6 The Difference Between Deleting and Hiding Display Filters
If you wish to remove a filter from the system permanently, then use the Delete procedure. However, if all
you want to do is remove a filter as a means to un-clutter the display, then use the Hide procedure.
Deleting a saved filter removes the filter from the current session and all subsequent sessions. In order to
retrieve a deleted filter, the user must recreate it using the
Set Conditions
dialog.
Hiding a filter merely removes the filter from the display. A hidden filter can be reapplied using the
Show/Hide procedure.
