How MAC Clone Operation:
•
ADM6996L/LX LAN traffic to LAN/CPU only. Traffic to another LAN port will be
untag packet. Traffic to CPU is Tag packet with VID=1. CPU can check VID to
distinguish LAN traffic or WAN traffic.
•
ADM6996L/LX WAN traffic to CPU only. Traffic to CPU is Tag packet with VID=2.
CPU can check VID to distinguish LAN traffic or WAN traffic.
•
ADM6996L/LX CPU Packet to LAN port must add VID=1 in VLAN field.
ADM6996L/LX check VID to distinguish LAN traffic or WAN traffic. LAN output
packet is Untag.
•
ADM6996L/LX CPU Packet to WAN port must add VID=2 in VLAN filed.
ADM6996L/LX check VID to distinguish LAN traffic or WAN traffic. WAN output
packet is Untag.
•
ADM6996L/LX will check VLAN mapping setting first then check learning table.
User does not worry LAN/WAN traffic mix up.
Bit 10: Half Duplex Back Pressure enable. 1/enable, 0/disable.
