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-

dr e s s a nd/ or type f i elds ( E t her net only) .

Inter-networking protocol recognition can be performed

on specific header or LLC information fields.
