NETWORK INTERFACES
External Address Detection Interface
(EADI)
The External Address Detection Interface can be used
to implement alternative address recognition schemes
outside the MACE device, to complement the physical,
logical and promiscuous detection supported internally.

The address matching, and the support logic neces-
sary to capture and present the relevant data to the ex-
ternal table of address is application specific. Note that
since the entire 802.3 packet after SFD is made avail-
able, recognition is not limited to the destination ad-
d r e s s a n d / o r t y p e f i e l d s ( E t h e r n e t o n l y ) .
Inter-networking protocol recognition can be performed
on specific header or LLC information fields.
