Data Sheet
Step 3: Set EEPROM 11
Step 1:
– If Untag packet received from LAN Port forwards to CPU Port, ADM6996M/MX will insert Special TAG
followed SA in the packets transmitted from the CPU port. ADM6996M/MX also allows users to choose what
kinds of packets they don't want to insert this Special TAG in.
