METHOD AND SYSTEM FOR ROUTING FIBRE CHANNEL FRAMES
First Claim
1. A method for transmitting frames using a fibre channel switch element, comprising:
- determining if a fibre channel switch element port link has been reset;
determining if a flush state has been enabled for the port; and
removing frames from a receive buffer, if the flush state has been enabled for the port.

Abstract
A method and system for transmitting frames using a fibre channel switch element is provided. The switch element includes a port having a receive segment and a transmit segment, wherein the fibre 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 fibre channel port as if it is a typical fibre 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.
