Inter-switch link identification and monitoring

A computer-implemented method, comprising:

• sending, by a processor, a query fabric path command from an origin endpoint to a first switch, the query fabric path command including an origin address corresponding to the origin endpoint and a destination address corresponding to a destination endpoint;
• receiving, by the processor, a query fabric path response from the first switch based on the query fabric path command, the query fabric path response including a plurality of port identifiers, wherein the plurality of port identifiers correspond to a plurality of expansion ports (E_Ports) of a plurality of inter-switch links (ISLs) between the first switch and a second switch, and wherein each of the plurality of ISLs is configured to transmit traffic between the origin endpoint and the destination endpoint;
• and
• monitoring, by the processor, the plurality of E_Ports.

A computer program product comprising:

• a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processing device to cause the processing device to perform a method comprising:
• sending a query fabric path command from an origin endpoint to a first switch, the query fabric path command including an origin address corresponding to the origin endpoint and a destination address corresponding to a destination endpoint;
• receiving a query fabric path response from the first switch based on the query fabric path command, the query fabric path response including a plurality of port identifiers, wherein the plurality of port identifiers correspond to a plurality of expansion ports (E_Ports) of a plurality of inter-switch links (ISLs) between the first switch and a second switch, and wherein each of the plurality of ISLs is configured to transmit traffic between the origin endpoint and the destination endpoint;
• and
• monitoring the plurality of E_Ports.
