摘要： A switch includes network ports and a network processor with a fabric interface that provides SerDes (Serializer/Deserializer) channels. The network processor divides each packet received over the network ports into cells and distributes the cells across the SerDes channels. Fabric ports of the switch communicate with the fabric interface to transmit cells to and receive cells from the fabric interface. The switch is selectively configurable as a standalone switch by connecting each fabric port of the switch to another of the fabric ports of the switch, as a member of a switch stack by connecting each fabric port of the switch to a different other switch through one fabric port of that other switch, or as a member of a distributed fabric system by connecting each fabric port of the switch to a different scaled-out fabric coupler (SFC) chassis by an SFC fabric port of that SFC chassis.

摘要： A scaled-out fabric coupler (SFC) chassis includes a plurality of root fabric cards installed on the one side of the SFC chassis. Each root fabric card has a plurality of electrical connectors. A plurality of line cards is installed on the opposite side of the SFC chassis. Each line card is one of two types of line cards. One of the two types of line cards is a switch-based network line card having network ports for connecting to servers and switches. The other of the two types of line cards is a leaf fabric card having fabric ports for connecting to a fabric port of a network element. Each of the two types of the line cards has electrical connectors that mate with one electrical connector of each root fabric card installed in the chassis.

摘要： A distributed virtual chassis comprises scaled-out fabric coupler (SFC) boxes. Each SFC box has fabric ports and a cell-based switch fabric for switching cells associated with a packet among the SFC fabric ports of that SFC box. Distributed line cards (DLCs) include switching DLCs and an appliance DLC (A-DLC). Each switching DLC has network ports. Each switching DLC and A-DLC has DLC fabric ports. Each switching DLC and A-DLC is connected to each of the SFC boxes. The A-DLC provides an upper layer service for packets arriving on the network ports of the switching DLCs. To forward a packet to the A-DLC, a switching DLC divides the packet into cells and distributes the cells among the SFC boxes. The SFC boxes forward the cells to the A-DLC, and the A-DLC reassembles the packet from the cells and provides the upper layer service to the packet.
