Method and system for routing fibre channel frames
First Claim
1. A method for a switch element, comprising:
- configuring a port of the switch element to operate in a repeat frame mode;
wherein during the repeat frame mode a transmit segment of the port continuously transmits a frame that is received from a common control segment of the switch element;
transferring the frame from the common segment that is managed by processor executable code for the switch element;
continuously transmitting the transferred frame; and
disabling the repeat frame mode using the common control segment.

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.

5. A switch element, comprising:
-
a plurality of ports, each port having a receive segment for receiving frames and a trans-mit segment for transmitting frames; and a configurable common segment for configuring the plurality of ports; wherein a port from among the plurality of ports is configured to operate in a repeat frame mode;
wherein during the repeat frame mode a transmit segment of the port continuously transmits a frame that is received from the configurable common control segment of the switch; and
processor executable code for the switch element disables the repeat frame mode using the configurable common control segment. - View Dependent Claims (6, 7, 8)

9. A method for a switch element for receiving and transmitting frames, comprising:
-
establishing a disposal policy for handling frames that are removed during a flush state operation;
wherein during the flush state operation a transmit segment of a port from among a plurality of ports of the switch element selectively removes a frame that is temporarily stored at a receive segment of the port;configuring the port to operate in a flush state; detecting a condition to trigger the flush state operation; removing frames stored at the receive segment of the port, without the receive segment being aware of the flush state operation; and disposing the frame based on the disposal policy set for handling frames that are removed during the flush state operation. - View Dependent Claims (10, 11, 12, 13)
