The specific traffic distribution algorithms are as follows:
For any bridged packet (except IP), the distribution is based on source and destination MAC:
■ MOD (DestMAC[5:0] XOR SrcMAC[5:0], number of active links)

For bridged and routed IP or routed IPX, the distribution is based on source and destination IP address:
■ MOD (DestIP(X)[5:0] XOR SrcIP(X)[5:0], number of active links)

Multicast flow distribution over MLT (MultiLink Trunking) is based on source-subnet and group addresses. To determine the port for a particular Source, Group (S,G) pair, the number of active ports of the MLT is used to MOD the number generated by the XOR of each byte of the masked group address with the masked source address. This feature was introduced in release 3.5. The feature is not enabled by default and must be enabled in order for IP multicast streams to be distributed.
