  • Port decommissioning
    Patent number: 9571423
    Abstract: A management application can automatically coordinate the decommissioning of ports in a switch, ensuring that ports are gracefully taken out of service without unnecessary interruption of service and triggering of automatic recovery functionality that may occur during manual decommissioning of ports. Embodiments may provide for decommissioning of F_ports only, E_ports only, or both F_ports and E_ports. Where link aggregation is provided for in the fabric, decommissioning of a port in a link aggregation group may be performed if there are other operational links in the group. Decommissioning of a non-aggregated port (or the last operational port in a link aggregation group) may be performed if there is a redundant path available.

  • Mapping logical ports of a network switch to physical ports
    Patent number: 8989201
    Abstract: A Layer 2 network switch is partitionable into a plurality of switch fabrics. The single-chassis switch is partitionable into a plurality of logical switches, each associated with one of the virtual fabrics. The logical switches behave as complete and self-contained switches. A logical switch fabric can span multiple single-chassis switch chassis. Logical switches are connected by inter-switch links that can be either dedicated single-chassis links or logical links. An extended inter-switch link can be used to transport traffic for one or more logical inter-switch links. Physical ports of the chassis are assigned to logical switches and are managed by the logical switch. Legacy switches that are not partitionable into logical switches can serve as transit switches between two logical switches.
