Abstract
A system and method for preventing untrusted nodes from sending or receiving management communications. In an environment such as an InfiniBand communication fabric, a management packet (e.g., a packet traversing virtual lane) is one of four types: 1) Request from a manager node (e.g., Subnet Manager or SM) to an endnode; 2) Reply from an endnode to a request from the manager; 3) Request from an endnode to the manager; and 4) Reply from the manager to the endnode. Switches (and other routing devices) are configured to allow untrusted nodes to send management packets of typesandonly, and to receive management packets of typesandonly. Trusted nodes (e.g., manager nodes, switches) can send and receive all types. Each port of a switch or routing device has an associated indicator reflecting the level of trust afforded the node or switch coupled to the port.
