摘要： In general, techniques are described in which a plurality of network switches automatically configure themselves to operate as a single virtual network switch. A virtual switch is a collection of individual switch devices that operate like as single network switch. As described herein, network switches in a network that are capable of participating in a virtual switch may automatically discover one another. The participating network switches may then elect one of the participating switches as a master switch. The master switch may generate forwarding information and store the forwarding information in the participating switches, including the master switch. The forwarding information causes the participating switches to act like a single network switch.

摘要： A method for enabling autonegotiation over an interface for which no autonegotiation standard exists comprises establishing network communication between a first network device and a second network device over a communication link. The first network device includes a first media access controller (MAC) associated with a communication port coupled to the communication link and a second MAC positioned between the first MAC and the communication port, and the second MAC operates as a proxy MAC for the first MAC. The first MAC outputs an outbound data communication to the communication port at a first communication rate. The proxy MAC intercepts the outbound data communication. The proxy MAC then outputs the outbound data communication to the communication port at a second communication rate different from the first communication rate.

摘要： Access switches in a switching system may use virtual aggregated links. When a link between an aggregation switch and an access switch fails, the link failure may be reflected in the virtual aggregated link and data traffic to another access switch may be switched away from the failed switch. A forwarding table in the access switch stores a number of entries that each define a correspondence between destination addresses and an output identifier for the switch. At least a first output identifier includes an aggregated link that represents a first set of possible output links. At least a second output identifier includes a virtual aggregated link, associated with a second network switch that represents a second set of possible output links. Destination addresses in the forwarding table for the virtual aggregated link correspond to network devices connected to the second network switch.
