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.

Abstract: One embodiment describes a network system. The system includes a primary enclosure including a network switch system that includes a plurality of physical interface ports. A first one of the plurality of physical interface ports is to communicatively couple to a network. The system further includes a sub-enclosure comprising a network interface card (NIC) to which a computer system is communicatively coupled and a downlink extension module (DEM) that is communicatively coupled with the NIC and a second one of the plurality of physical interface ports of the network switch system to provide network connectivity of the computer system to the network via the network switch system.

Abstract: An example device includes a processor; a first interface port forming a first datalink to a core network device via a first interconnect device; and a second interface port forming a second datalink to the core network device via a second interconnect device, the first and second datalinks being redundant connections of a link aggregation group (LAG) including a plurality of multiplexed connections within a single network media. The processor is to: remove the first interconnect device while maintaining the second datalink; update firmware of the first interconnect device upon receiving a first indication that the first interconnect device has stopped receiving or transmitting data; and reestablish the redundant connections of the first interconnect device upon receiving a second indication that the first interconnect device has been added back to the LAG. The first and second indications include indications of states in each connection of the multiplexed connections.
