Function Description
Chapter 3 Function Description
3.1 Introduction
The ADM6926 uses a “store & forward” switching approach for the following reasons:
1)
Store & forward switches allow switching between different speed media (e.g.
10BaseX and 100BaseX). Such switches require the large elastic buffers, especially
bridging between a server on a 100Mbps network and clients on a 10Mbps segment.
2)
Store & forward switches improve overall network performance by acting as a
“network cache”
3)
Store & forward switches prevent the forwarding of corrupted packets by the frame
check sequence (FCS) before forwarding to the destination port.
3.1.1 Basic Operation
The ADM6926 receives incoming packets from one of its ports, uses the source address
(SA) and VID to update the address table, and then forwards the packet to the output
ports determined by the destination address (DA) and VID.
If the DA and VID are not found in the address table, the ADM6926 treats the packet as a
broadcast packet and forwards the packet to the other ports within the same group.
The ADM6926 automatically learns the port number of attached network devices by
examining the SA and VID of all incoming packets. If the SA and VID are not found in
the address table, the device adds it to the table.
3.1.2 Address Learning
The ADM6926 provides two ways to create the entry in the address table: dynamic
learning and manual learning. A four-way hash algorithm is implemented to allow 4
different addresses to be stored at the same location. Up to 4k entries can be created and
all entries are stored in the internal SSRAM. Two parameters, SA and VID, are combined
to generate the 10-bit hash key to allow that the same addresses with different port
number can exist in the table at the same time.
1. Dynamic Learning
The ADM6926 searches for SA and VID of an incoming packet in the address table and
acts as follows:

If the SA+VID was not found in the address table (a new address), the ADM6926 waits
until the end of the packet (non-error packet) and updates the address table. If the
