13.3.4.2 PVROUTE 0
Registers PVROUTE0 to PVROUTE7 allows the VLAN Index to be assigned an address of a router group. This
feature is useful during IP Multicast mode when data is being sent to the VLAN group and no member of the group
registers. By assigning a router group, the VLAN group always has a default address to handle the multicast traffic.
CPU Address:h171
Accessed by CPU, serial interface (R/W)
Bit [4]:
Support MAC address 0 (Default = 0)
0: MAC address 0 is not learned.
1: MAC address 0 is learned.
Bit [5]:
Disable IEEE multicast control frame (0180C2000000 to 0180C20000FF)
to CPU in managed mode (Default = 0)
0: Packet is forwarded to CPU
1: Packet is forwarded as multicast
Bit [6]:
Multiple MAC addresses (Default = 0)
0: Single MAC address is assigned to CPU. Registers MAC0 to MAC5 are
used to program the CPU MAC address.
1: One block of 32 MAC addresses are assigned to CPU. The block is defined
in an increase way from the MAC address programmed in registers MAC0 to
MAC5.
Bit [7]:
Disable registers MAC 5 – 0 (CPU MAC address) in comparison with
Ethernet frame destination MAC address. When disable, unicast frames
are not forward to CPU. (Default = 0)
1: Disable
0: Enable
Bit [0]:
VLAN Index 8’hC0 has router group and the router group is VLAN Index 8’h40
Bit [1]:
VLAN Index 8’hC1 has router group and the router group is VLAN Index 8’h41
Bit [2]:
VLAN Index 8’hC2 has router group and the router group is VLAN Index 8’h42
Bit [3]:
VLAN Index 8’hC3 has router group and the router group is VLAN Index 8’h43
Bit [4]:
VLAN Index 8’hC4 has router group and the router group is VLAN Index 8’h44
Bit [5]:
VLAN Index 8’hC5 has router group and the router group is VLAN Index 8’h45
Bit [6]:
VLAN Index 8’hC6 has router group and the router group is VLAN Index 8’h46
Bit [7]:
VLAN Index 8’hC7 has router group and the router group is VLAN Index 8’h47
