Abstract
A method and system for transmitting frames using a fiber channel switch element is provided. The switch element includes a port having a receive segment and a transmit segment, wherein the fiber channel switch element determines if a port link has been reset; determines if a flush state has been enabled for the port; and removes frames from a buffer, if the flush state has been enabled for the port. For a flush state operation, frames are removed from a receive buffer of the fiber channel port as if it is a typical fiber channel frame transfer. The removed frames are sent to a processor for analysis. The method also includes, setting a control bit for activating frame removal from the transmit buffer; and diverting frames that are waiting in the transmit buffer and have not been able to move from the transmit buffer.
