ABSTRACT:
A fiber channel switch element for routing fiber channel frame is provided. The switch element includes a fiber channel port that can be configured to support plural data transfer rates. The data transfer rate may be 1 G, 2 G, 4 G, 8 G or 10 G. The switch element includes a clock configuration module for providing a clock signal that is based on the data transfer rate. A receive segment of the fiber channel port sends a signal to a transmit segment to avoid an under flow condition. The receive segment also waits for a certain frame length after a fiber channel frame is written and before the fiber channel frame is read, depending upon a data transfer rate of a source port. Multiple lanes may be configured as a single 10 G multi lane port or as multiple individual ports.
