Abstract
Embodiments according to the invention relate to frame redirection, which includes methods to intercept and re-route traffic between an initiator and a target. When a frame is redirected, an initiator issues a frame to the target, but the frame is received by a virtual target in a redirection switch by allowing the redirection switch to use the WWN of the actual target. From the perspective of the initiator, the target resides on the redirection switch. From the redirection switch, the frame is sent to the actual target by allowing the redirection switch to use the identity of the initiator. In other words, the redirection switch presents the WWN of the initiator to the target when the redirected frame is sent to the target. From the perspective of the target, the frame is received as if it originated at the initiator.
