Setting Filter Expressions
You can set filter expressions by specifying parameters for frame filters.
You can also create a filter expression, which is executed in ascending
order based on the ExprSeq values until the access point determines
whether to pass or drop the frame.
To set filter expressions
1. From the Main Menu, select Ethernet then Advanced Filters.
2. Select Filter Expressions. The Filter Expressions screen appears.
3. Configure the Filter Expressions parameters. These parameters are
described below:
ExprSeq (Expression Sequence)
Indicates the order in which the filters will be executed. When you
change the parameter, the statements are reordered and
renumbered so the Expression Sequence order is maintained. The
range is from 0 to 255.
