DESCRIPTIONS
The Accept Broadcast Packet controls the broadcast packet
reception. If ABP is enabled, EMC receives all incoming packet it’s
destination MAC address is a broadcast address.
1’b0: EMC receives packet depends on the CAM comparison result.
1’b1: EMC receives all broadcast packets.
The Accept Multicast Packet controls the multicast packet reception.
If AMP is enabled, EMC receives all incoming packet it’s destination
MAC address is a multicast address.
1’b0: EMC receives packet depends on the CAM comparison result.
1’b1: EMC receives all multicast packets.
The Accept Unicast Packet controls the unicast packet reception. If
AUP is enabled, EMC receives all incoming packet it’s destination
MAC address is a unicast address.
1’b0: EMC receives packet depends on the CAM comparison result.
1’b1: EMC receives all unicast packets.
CAMCMR Setting and Comparison Result
CAMCMR Setting and Comparison Result
The following table is the address recognition result in different CAMCMR configuration. The
column Result shows the incoming packet type that can pass the address recognition in specific
CAM configuration. The C, U, M and B represents the:
C: It indicates the destination MAC address of incoming packet has been configured in CAM entry.
U: It indicates the incoming packet is a unicast packet.
M: It indicates the incoming packet is a multicast packet.
B: It indicates the incoming packet is a broadcast packet.
