Abstract

A system and method can use a secure subnet management agent (SMA) to perform fencing operations in an InfiniBand (IB) fabric. A host channel adapter (HCA) in the fabric can be associated with a plurality of ports, wherein the HCA operates to implement a SMA in its embedded firmware. Furthermore, the SMA operates to be used as a proxy, by a port on the HCA, for updating one or more states associated with another port on the HCA. The one or more states are associated with at least one of updating a management key and resetting a link at another port on the HCA.
