Abstract: Methods and systems are disclosed. Methods and systems include enabling MacSec in a frontside stacking environment. The method includes: creating a prepended frame descriptor to a packet; and placing SecTag control information in the prepended frame descriptor. Further methods and systems include enabling Pause and OAM in a frontside stacking environment. The method includes: identifying a size of a packet; and if the size of a packet is less than or equal to 64 bytes, examining the packet for a Pause or an OAM frame format.

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.

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: 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.
