In accordance with a non-limiting example, a communications system includes a plurality of Virtual Local Area Networks (VLAN) enabled switches interconnected together and each having a plurality of ports and configured into a plurality of VLAN's in a single topology map. The switches each comprise a processor and transceiver and configured to process and transport data packets and further comprising forwarding tables and operating in accordance with a Spanning Tree Protocol in a single topology map, for example, operating with the Rapid Spanning Tree Protocol and not having multiple topologies. When a topology changes occurs to a specified VLAN, the switches are configured to flush the forwarding tables only for the specified VLAN associated with the port of the switch whose state change caused the topology change.
