Abstract
Method and system for checking frame-length in a Fiber Channel frames is provided. The method includes extracting a R_CTL value from a Fiber Channel frame; comparing the extracted R_CTL value of the Fiber Channel frame with R_CTL values stored in a Content Addressable Memory Table; determining a maximum frame-length and a minimum frame-length of the Fiber Channel frame for the extracted R_CTL value from the Content Addressable Memory Table; and marking the Fiber Channel frame so that it can be discarded if the frame-length is less than the minimum frame-length of the Fiber Channel frame or greater than the maximum frame-length of the Fiber Channel frame. The system includes a processor that accesses a CAM stored in memory; and a receive port that extracts and compares a R_CTL value of the Fiber Channel frame.
