    摘要： A method may involve: receiving a packet (e.g., via a port or uplink interface in a satellite switch) and conveying the packet between one or more ports and one of several uplink interfaces. The one or more ports and the uplink interface are associated with each other. The association can be independent of VLAN (Virtual Local Area Network). As an example, such a method can involve: receiving a first packet via a first port; conveying the first packet to a distribution-layer via a first uplink interface; receiving a second packet via a second port; and conveying the second packet to the distribution-layer via a second uplink interface, where the first uplink interface is associated with the first port and the second uplink interface is associated with the second port. In some embodiments, ports and uplink interfaces are associated by being assigned to the same virtual linecard.

    摘要翻译： 方法可以包括：接收分组（例如，经由卫星交换机中的端口或上行链路接口）并且在一个或多个端口与多个上行链路接口中的一个之间传送分组。 一个或多个端口和上行链路接口彼此相关联。 该关联可以独立于VLAN（虚拟局域网）。 作为示例，这种方法可以包括：经由第一端口接收第一分组; 经由第一上行链路接口将所述第一分组传送到分发层; 经由第二端口接收第二分组; 以及经由第二上行链路接口将所述第二分组传送到所述分发层，其中所述第一上行链路接口与所述第一端口相关联，并且所述第二上行链路接口与所述第二端口相关联。 在一些实施例中，端口和上行链路接口通过分配给相同的虚拟线卡相关联。

    摘要： An adjunct network device includes several ports, an uplink interface, and an adjunct forwarding engine coupled to the ports and the uplink interface. A first port is configured to receive a packet, which includes a destination address. The adjunct forwarding engine is configured to send the packet to the uplink interface if the destination address is not associated with any of the ports. The packet is sent to one of the ports if the destination address is associated with the one of the ports.

    摘要： Method and devices are provided to form virtual switches for data networks. As noted above, the term “switch” as used herein will apply to switches, routers and similar network devices. Each virtual switch acts as a single logical unit, while encompassing at least two physical chassis. Accordingly, each virtual switch may be treated as a single point of management. Each virtual switch includes a master chassis and at least one slave chassis. The master chassis is configured to control the slave chassis. The master chassis includes at least one master supervisor card and the slave chassis includes at least one slave supervisor card. The master chassis and the slave chassis communicate via a virtual switch link according to a virtual switch link protocol.
