Example
The user needs Samurai-
6M/6MX (ADM6996M/MX)
to forward the specified
unicast packet (DA = 0012-
3456-789A
port 3 forever.
The user needs Samurai-
6M/6MX (ADM6996M/MX)
to forward the specified
multicast packet (DA =
0123-4567-89AB
= 3) to port 0, and port 1
both. This address could be
aged.
The user wants to know how
many stations attached to
port 4
3.1.17
Samurai-6M/6MX (ADM6996M/MX) supports IGMP v1/v2 Snooping without any software effort. Samurai-6M/6MX
(ADM6996M/MX) will monitor the IGMP traffic and update its embedded IGMP membership table if the hardware
based IGMP snooping function is enabled. IP multicast frames can be forwarded according to the Port-Map
information of the membership table. The data of the membership can also be accessed by the CPU via
SDC/SDIO interface. The following registers could be used to configure the IGMP Snooping behavior.
1. EEPROM register 00B
2. EEPROM register 00B
3. EEPROM register 00B
4. EEPROM register 00C
5. EEPROM register 00C
6. EEPROM register 00C

8. Read the status register 5 to check the busy bit. If Busy = 0
1. Check the Busy bit. If Busy = 0
2. Write 0030
3. Wait until the Busy bit changes to 0
4. Write 0100
5. Write 0029
6. Read the status register 5 to check the busy bit. If Busy = 0
7. If Command Result = “Command OK”, it means some other MAC addresses
8. If the Command Result = “Entry Not Found”, it means no other addresses

attached to port 4 could be derived from the MAC address in the status register).
If Busy = 1

again to let the search engine look after another addresses.
