摘要： Some embodiments can determine an internal virtual network identifier and/or an internal policy identifier for a packet based on a port on which the packet was received and/or one or more fields in the packet. The system can then process and/or forward the packet based on the internal virtual network identifier and/or the internal policy identifier. Some embodiments can perform remote port mirroring. Some embodiments can map a first set of QoS bits in a packet to a second set of QoS bits for use in a Transparent Interconnection of Lots of Links (TRILL) packet which encapsulates the packet. Some embodiments can efficiently support multiple multicast trees and for performing network layer multicasting in TRILL networks. Some embodiments can flood packets on a per-virtual-network basis.

摘要： One embodiment of the present invention provides a switch (600). The switch includes an inter-switch multicast module (630) and an edge multicast module (640). The inter-switch multicast module identifies for a first replication of a multicast packet an egress inter-switch port in a multicast tree rooted at the switch. The multicast tree is identified by an identifier of the switch. The edge multicast module identifies an egress edge port for a second replication of the multicast packet based on a multicast group identifier. The multicast group identifier is local within the switch.

摘要： One embodiment of the present invention provides a switch. The switch includes a fabric switch module and a border module. The fabric switch module maintains a membership in a first fabric switch. The fabric switch includes a plurality of switches and operates as a single logical switch. The border module determines that the egress switch identifier in a first encapsulation header of a first packet is associated with a switch outside of the fabric switch. The first packet is forwardable in the first fabric switch based on the first encapsulation header. In response to the determination, the border module changes the ingress switch identifier in the first encapsulation header of the first packet to a first virtual switch identifier associated with a first virtual switch. This first virtual switch externally represents the first fabric switch.
摘要翻译：本发明的一个实施例提供一种开关。交换机包括一个Fabric交换模块和一个边界模块。结构交换模块维护第一个结构交换机的成员资格。结构交换机包括多个交换机，并作为单个逻辑交换机运行。边界模块确定第一分组的第一封装报头中的出口交换机标识符与交换机外部的交换机相关联。第一个数据包可以在第一个结构交换机中基于第一个封装头来转发。响应于该确定，边界模块将第一分组的第一封装报头中的入口交换机标识符改变为与第一虚拟交换机相关联的第一虚拟交换机标识符。第一个虚拟交换机外部代表第一个Fabric交换机。
