    摘要: 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.

    摘要: A Layer 2 network switch fabric is partitionable into a plurality of virtual fabrics. A network switch chassis is partitionable into a plurality of logical switches, each of which may be associated with one of the virtual fabrics, including a base switch. Logical switches in multiple network switch chassis are connected by logical connections, such as logical inter-switch links that use physical connections, such as extended inter-switch links between base switches, for data transport. A topology of logical connections is established that balances competing metrics, such as robustness and scalability, while maintaining alignment with the topology of the physical connections. A topology factor allows establishing different topologies with different balances between the competing metrics.
