Switched fabric network routing mode selection

Abstract:

Embodiments include methods, systems, and computer program products for routing mode selection in a switched fabric network. A fabric login request including a fabric login payload is received at a network device to establish communication parameters with a switched fabric network. The network device can determine whether the fabric login payload includes an extension for routing policy support and whether a current routing policy of the network device is compatible with a routing mode defined in the fabric login payload based on the extension for routing policy support. The fabric login request can be rejected based on determining that the current routing policy of the network device is incompatible with the routing mode defined in the fabric login payload. The fabric login request is completed based on determining that the current routing policy of the network device is compatible with the routing mode defined in the fabric login payload.
