[Advanced RX Filter]

If you need more flexibility than that provided by [Normal

RX Filter], you can use the tables for [Advanced RX Filter]

to specify additional filters. Settings for [Advanced RX

Filter] execute after those for [Normal RX Filter]. For

example, if [Normal RX Filter] dropped a frame, the frame

cannot be “undropped.” If [Normal RX Filter] passed a

frame, [Advanced RX Filter] then executes.
Specifying an advanced filter for [Advanced RX Filter] is

more complicated than specifying one for [Normal RX

Filter]. If possible, use [Normal RX Filter] to set filters.
[Advanced RX Filter] options are:

[Expressions]
[Values]

[Expressions]

Use [Expressions] to enter expressions used to match the

patterns stored in pattern lists to consecutive bytes in

received Ethernet frames. Settings for Expressions execute

in sequence until a determination is made to pass or drop

the frame, as follows:

"

If the last Then listed in this table is Then Drop, the

table’s default is an implied Else Pass.

"

If the last Then is Then Pass, the default is an implied

Else Drop.

The Value Table displays the filter expressions to be

executed:
