Claim:
1. A method of limiting flooding on a network comprising: a) determining if a port is identified for a limited flooding process; b) when the port is identified for the limited flooding process, determining if the port will not currently have any devices with unknown destination addresses connected to the port; c) when it is determined that the port will not currently have any devices with the unknown destination addresses connected to the port, suppressing the forwarding of unicast frames with the unknown destination addresses on the port, determining if the port is in a full duplex port; if the port is in the full duplex port, determining if the port is in a trunk mode; if the port is not in the trunk mode, determining if a bridge protocol data unit has been received; if the bridge protocol data unit has not been received, setting the port for the limited flooding process; and when the port is not in the full duplex port, not setting the port to the limited flooding process.
