• Manufacturer Part Number: zl50411
• Description: Managed 9-port Fast Ethernet Switch With Private Vlan
• Manufacturer: Zarlink Semiconductor

12.3.4
MAC5 to MAC0 registers form the CPU MAC address. When a packet with destination MAC address match MAC
[5:0], the packet is forwarded to the CPU. The default MAC address is 00-00-00-00-00-00.
12.3.4.1
CPU Address: h0300
Accessed by CPU (R/W)
12.3.4.2

MAC5
Byte 1 (bits [15:8]) of the CPU MAC address (Default 0)
MULTICAST_HASH1-1
Unknown IP Multicast Filter Enable
1: Enable (default)
0: Disable
If this feature is enabled, unknown IP multicast packets or unknown multicast
packets can be either filtered or sent to the CPU, based on bits [13:12] in the per
VLAN Port Association table.
This feature is only applicable in tagged-based VLAN mode (PVMODE[0]=’1’). In
port-based VLAN mode (PVMODE[0]=’0’), this bit is ignored.
MULTICAST_HASH[7:2,0]-1
Reserved (Default 0x1)
Reserved (Default 0x7)
MULTICAST_HASH0-1
Hash Select. The hash algorithm selected is valid for all trunks
00 - Use Source and Destination MAC Address for hashing
01 - Use Source MAC Address for hashing
10 - Use Destination MAC Address for hashing
11 - Use Source Port Number for hashing (Default)
MULTICAST_HASH[7:1]-1
Reserved (Default 0x3)
Byte 0 (bits [7:0]) of the CPU MAC address (Default 0)
