Abstract

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