Abstract: Some implementations of the disclosure are directed to an interconnect including: a plurality of ports; a processor; and a non-transitory computer readable medium have instructions stored thereon, that when executed by a processor, cause the interconnect device to: track a link state of a first port of the plurality of ports, where tracking the link state of the first port comprises tracking when a physical link of the first port transitions between a linked state and an unlinked state; determine, using at least the tracking of when the physical link of the first port transitions between the linked state and the unlinked state, that the first port is in an unstable link state; and when the first port is in an unstable link state, transmitting a message to an interconnect management device, the message including an indication that the first port is in an unstable link state.

Abstract: A network switching environment includes a network switch coupled to a port extension module by one or more network cables, and a management resource coupled to the switch and the port extension module. The configurations of the network switch and the port extension module may be dynamically controlled by a management resource to adjust to changes in the maximum bandwidth provided by the one or more network cables. The management resource may implement the network switch and port extension module configurations according to a predetermined target configuration and the connection configuration of the network switch and the port extension module.

Abstract: A system to facilitate identification of intermediate switches within a network switching fabric is described. The system includes a processor and a machine readable medium storing instructions that, when executed, cause the processor to detect a neighbor change event at a switch port of a network switch, determine whether a switch port neighbor device coupled to the switch port is trusted, set a status of the switch port as failed upon a determination that the switch port is untrusted, block network traffic through the switch port and generate an alert indicating that untrusted switch port neighbor device is coupled to the switch port.
