Function Description
DA
DA+VID was found in the
address table (entry not pointed
to the output port map table)
DA+VID was found in the
address table (entry pointed to the
output port map table)
DA+VID was not found in the
address table
No Security Violation
Forward packets to the port
determined by the address table.
The packet may be dropped
because of forwarding group
boundary violation.
Forward packets to the ports
determined by the output port
map table constrained by the
forwarding group.
Forward packets according the
Multicast Option.
Security Violation
IGMP Packet

3.1.5 Trunking Port Forwarding
ADM6926 supports the trunking forwarding and any port could be assigned to the
trunking port. When one or more of the members link fail, the ADM6926 will
automatically change the transmit path from the failed link port to normal link port. Port
based load balancing is implemented to distribute the loading.
3.1.6 Illegal Frames
The ADM6926 will discard all illegal frames such as runt packet (less than 64 bytes),
oversize packet (greater than 1518 or 1522 bytes) or bad CRC.
3.1.7 Back off Algorithm
The ADM6926 implements the truncated exponential back off algorithm compliant to the
802.3 standard. ADM6926 will restart the back off algorithm by choosing 0-9 collision
count. After 16 consecutive retransmit trials, the ADM6926 resets the collision counter.
3.1.8 Buffers and Queues
ADMtek Inc.
3-4
The ADM6926 incorporates 26 transmit queues and receive buffer area for the 26
Ethernet ports. The receive buffers as well as the transmit queues are located within the
ADM6926 along with the switch fabric. The buffers are divided into 640 blocks of 256
