Abstract
In a method for running a computer network (2) comprising a number of devices (4a-d) being arranged in a daisy-chained loop and running a spanning-tree algorithm (10) involving handling of state machines (14), wherein each device (4a-d) comprises a bridge (6a-d) having at least three ports (8a-c), whereby during running the network (2) each device (4a-d) can take different states (D, L, F, O) to avoid a loop in the network (2), whereby logical port states (D, L, F, O) of the ports are defined by the state machines (14), for at least one device (4a-d) at least once before a reboot of the device (4a-d) a momentary state (S) of a state machine (14) is stored, and in case of rebooting the state (D, L, F, O, S) of the device (4a-d) is restored, if it is successfully validated that the stored state (S) is still valid. A Computer network (2), comprising a number of devices (4a-d) being arranged in a daisy-chained loop is adapted for performing the method above.
