3.1.18
Samurai-6M/6MX (ADM6996M/MX) maintains an age timer for each address. The aging timer is reset to 0 when
the packet is received. When aging time counts up to 300 seconds, it means that station didn’t transmit packets
in this period and the address can be removed from the table. This could help to prevent a station which leaves
the network and occupies a table space for a long time. Aging function can be disabled from the EEPROM (see
extend control registers) and if the address is static, then Samurai-6M/6MX (ADM6996M/MX) will not age it out
either. The default aging timer is 300 seconds. User could change Aging Timer Select (0011
aging time.
3.1.19
Source violation is defined in Samurai-6M/6MX (ADM6996M/MX) to support flexible security modes. See Security
Option in the EEPROM Basic Register and the Src_Violation bit in the Learning Table.
Data Sheet
IGMP membership table Read Command
– (1) Check the Busy Bit in the Status Register 5 [15] to see if the access engine is available. If Busy = 1
– (2) Write Control Register 4 [4:0] to assign the entry numbers you want to access.
– (3) Write Control Register 5 [6:4] = 101
– (4) Read the Busy Bit in the Status Register 5 [15] to see if the operation is successful. If Busy = 1
IGMP membership table Write Command
– (1) Check the Busy Bit in the Status Register 5 [15] to see if the access engine is available. If Busy = 1
– (2) Write Control Register 0 ~ 4 to assign the entry numbers you want to access.
– (3) Write Control Register 5 [6:4] = 100
– (4) Read the Busy Bit in the Status Register 5 [15] to see if the operation is successful. If Busy = 1
wait until the engine is free. If Busy = 0
until the operation is completed. If Busy = 0
entry.
