MULTI-ROLE DISTRIBUTED LINE CARD

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.

主权项

1. A network switch comprising:
a plurality of network ports receiving packets over a network; a network processor in communication with the network ports, the network processor having a fabric interface that provides a plurality of SerDes (Serializer/Deserializer) channels, the network processor dividing each packet received over the network ports into a plurality of cells and distributing the cells of each received packet across the SerDes channels; and a plurality of fabric ports in communication with the fabric interface of the network processor to transmit cells to and receive cells from the fabric interface, each of the fabric ports being connected to one of the other fabric ports to produce a standalone network switch.
