Creation and deletion of logical ports in a logical switch

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.

1. A method of connecting logical switches in a network, comprising:
establishing a logical inter-switch link between a first logical switch in a first chassis and a second logical switch in a second chassis, the logical inter-switch link using one or more extended inter-switch links for data transport between the first chassis and the second chassis; creating a logical port of the first logical switch, wherein the logical port is not mapped to a physical port of the first chassis; and associating the logical port with the logical inter-switch link, wherein logical inter-switch link is not a physical inter-switch link between the first logical switch and the second logical switch, and wherein one of the one or more extended inter-switch links is a physical inter-switch link connected to the first chassis.
