Abstract

Techniques are disclosed to reduce crossover between traffic from switch elements of different switch domains in a distributed switch. Addition of a first switch element to the distributed switch is detected. The distributed switch includes multiple switch elements at least subsequent to the addition, and each switch element has a switch element identifier and a fabric identifier. The respective fabric identifiers of the first switch element and of a second switch element are retrieved. The second switch element is communicably connected to the first switch element via a link, and the link is configured to allow only command traffic to be transmitted via the link. Upon a determination that the fabric identifier of the first switch element does not match the fabric identifier of the second switch element, then no command is issued specifying to reconfigure the link to allow at least one additional traffic type, different from command traffic.
