A method of managing connectivity between an end-device and one of a plurality of bridging-devices connected to the end-device. The method includes transmitting test messages by each of the bridging-devices, transmitting test messages by the end-device, determining, in each of the bridging-devices, with which of the other devices there is an operative connection, based on the test messages the bridging-device receives and determining, in each of the bridging-devices, whether a port leading to the end-device should be in a forwarding or blocking state responsive to the determination of the operative connections.

Distributed port-blocking method

A method of managing connectivity of a cluster of bridging-devices including a plurality of links. The method includes pre-designating at least one of the links as a redundant link which is blocked when all the other links are operative and connected in accordance with a predetermined scheme, determining connectivity data on the connectivity of the links of the cluster, and activating or blocking the pre-designated redundant at least one link responsive to the connectivity data.
