Constructing and verifying switch fabric cabling schemes

摘要

A distributed network switch includes multiple switch modules connected by one or more physical cables. One switch module may determine which connector port of a remote switch module is connected by physical cable based on information received from the remote switch module, including link identifiers, and further based on a physical topology predetermined about the type of remote switch module.

主权项

1. A computer program product for verifying cabling of a distributed network switch, the computer program product comprising:
a non-transitory computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code comprising: computer-readable program code, executable by a processor, configured to detect that a physical connection has been made from a first switch module to a second switch module, wherein the physical connection comprises a plurality of links including a first link, wherein the first link connects a first sub-switch element of a first plurality of sub-switch elements within the first switch module to a second sub-switch element of a second plurality of sub-switch elements within the second switch module; computer-readable program code configured to determine a link identifier associated with the first link based on a first port identifier of the first sub-switch element and on a second port identifier of the second sub-switch element; computer-readable program code configured to retrieve, from a memory of the second switch module, information associated the second switch module; computer-readable program code configured to retrieve a physical topology associated with the second switch module from a catalog of switch modules based on the retrieved information; and computer-readable program code configured to determine, by execution of a processing element in the first switch module, a connector port of the second switch module associated with the physical connection based on the physical topology and on the link identifier.
