This screen allows you to set up filters and masks for the reception of Ethernet

It is possible to let the Port 2 copy the setup from Port 1 by touching the
FollowFollow button. When this button is displayed in green, Port 2 continues to
follow Port 1 change. This button appears when the Port 1 settings can be copy
to Port 2.
The filter and mask table shows the currently existing filters. There are 8 rows,
each representing a filter which (when enabled) is applied to each received
frame. Each filter is composed as a set of values and/or masks (e.g. MAC
destination address, IP addresses etc.). If all values in at least one enabled
row/filter matches, the frame will pass.
If the mask for a specific value is enabled, only bits that are "1"/on are
compared to the frame. For instance, if MAC Destination value is '00-12-34-56-
78-9A' and the mask is set to '00-FF-00-FF-FF-FF', only frames with MAC
addresses 'XX-12-XX-56-78-9A' will pass.
To specify the set of values and/or masks available for each filter (i.e. the
columns of the table), touch the Select FilterSelect Filter button. This will launch the filter
editor dialog box, which contains a number of check boxes for enabling filters
and masks on different addresses.
