Abstract

A system and method can provide subnet manager (SM) restrictions in an InfiniBand (IB) network. A first SM in a subnet in the IB network operates to determine whether a second SM associated with a remote port is trustworthy. Furthermore, the first SM is allowed to send at least one of a request and a response that contains a management key to the second SM, if the first SM determines that the second SM is trustworthy. Additionally, the first SM is prevented from attempting to initiate communication with the second SM, if otherwise.
