Security/Filter Defines
The Express L128/L128T can filter packets based on certain parameters within 
the packet.  The method used by the Express L128/L128T allows the highest 
flexibility for defining filters and assigning them to a Connection List profile.  
The filters are set up in two steps: (1) defining the packet types, and (2) adding 
them to a list under the Connection List profile. See the section Connection List/
Filters
 on page 79 for examples of how to set up filter profiles.  This menu is 
used to define the individual filter defines based on packet type.
Filter Defines /MAC Filter Defines
Write security: 2; Read security: 3
The MAC filter is applied to bridge packets only. Bridge packets which are for-
warded by the bridge functionality of the Express L128/L128T are defined 
here.  Up to 32 MAC defines can be specified.
