Abstract
A system and method can support automatic disabling of degraded links in an InfiniBand (IB) network. At least one node in a fabric can monitor one or more local ports of the at least one node for one or more error states associated with a link at the at least one node, wherein the link is connected to a local port of the at least one node. The at least one node further allows a subnet manager to observe the one or more error states associated with the link at the at least one node, and allows the subnet manager to set the link in a basic state if the observed error states exceed a threshold. In this basic state, the link allows only SMP traffic and prevents data traffic and non-SMP based management traffic.
