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: 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: 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 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.
