New Router application works well on the normal application. If user’s ISP vendor (cable modem) lock Registration
Card’s ID then Router CPU must send this Lock Registration Card’s ID to WAN Port. One condition that may
happen is that there exists two same MAC ID on this Switch. One is the original Card and another one is CPU.
This will make Switch learning table have the trouble.
ADM6999G/GX provides MAC Clone function that allows two the same MAC addresses with different VLAN ID0
on learning table. This will solve Lock registration Card’s ID issue. ADM6999G/GX serial chip will put these two
same MAC addresses with different VLAN ID0 at different learning table’s entry.
How to Set ADM6999G/GX on Router:
•
•
•
Step1: Set Register 11
{Coding: Write Register 11
Step2: Set Port0~3 as Untag Port and set PVID = 1.
{Coding: Write Register 01
Step3: Set Port4 as Untag Port and set PVID = 2.
{Coding: Write Register 08
Step4: Set Port5 MII Port as Tag Port and set PVID = 2.
{Coding: Write Register 09
Step5: Group Port0, 1, 2, 3, 5 as VLAN 1.
{Coding: Write Register 14
Step6: Group Port4, 5 as VLAN 2.
{Coding: Write Register 15
