Abstract: Methods and systems for configuring a first switch for frontside networking. The method includes: discovering the capabilities of a second switch connected to the first switch, where the capabilities include frontside stacking; changing a port on the first switch connected to the second switch from a standard port to a frontside stacking port; discovering a topology of a network containing the first switch and the second switch; and creating a drop table having entries for at least the first switch and the second switch.

Abstract: A method for resolving split conditions in a port-extended network comprises receiving first information indicative of a first MAC address of a first controller on a first fabric link and second information indicative of a second MAC address of a second controller on a second fabric link. The method may also include determining that the first MAC address differs from the second MAC address and responsively determining that one of the first MAC address or the second MAC address was previously associated with a primary controller of the port-extended network. One of the first controller or the second controller is designated as the primary controller of the port-extended network based on the determination that one of the first MAC address or the second MAC address was previously associated with the primary controller.

Abstract: Methods and systems are disclosed. The method comprises: designating a first plurality of links from a first stack segment to a second stack segment as a first etherchannel link; designating a second plurality of links from the first stack segment to a third stack segment as a second etherchannel link, where the second stack segment and the third stack segment are in communication with a fourth stack segment; designating the first etherchannel link and the second etherchannel link as members of a hierarchical etherchannel link; and sending a packet from the first stack segment to the fourth stack segment using the hierarchical etherchannel link.

Abstract: Detection and configuration of a logical channel may be provided. First, data traffic received on a plurality of ports of a first network device may be analyzed by a computing device. Next, based upon analyzing the data traffic received on the plurality of ports, the computing device may determine that the plurality of ports comprise a logical channel from the perspective of a second network device. The plurality of ports may then be configured as the logical channel on the first network device based upon determining that the plurality of ports comprise the logical channel from the perspective of the second network device.

Abstract: A method for specialized processing of data in a port-extended network comprises receiving, by the control node of the port-extended network, a data frame that includes, at a first field of the data frame, information indicative of an incoming port at which the data frame was received, the first field having been inserted by a satellite node associated with the port. The method also comprises determining that one or more packets of a frame require specialized processing, and replacing the information contained in the first field with information indicative of the specialized processing. The method further comprises replacing information contained in a second field with information indicative of an outgoing port of a second satellite node of the port-extended network. A modified data frame is transmitted onto the port-extended network, the modified data frame that includes the information indicative of the specialized processing in the first field.
