Claim Text:
1. A method, comprising: detecting a correctable symbol error ratio (SER) for a high-speed link which employs forward error correction (FEC); and disconnecting or temporarily pausing the high-speed link if the correctable SER exceeds a predetermined threshold, wherein the high-speed link couples a pair of link partners in communication and includes four Forward Error Correction (FEC) lanes, and each link partner includes a Physical (PHY) interface including a Reed-Solomon Forward Error Correction (RS-FEC) sublayer, and wherein detecting the correctable SER comprises employing a Reed-Solomon decoder in the RS-FEC sublayer to count a number of correctable symbol errors detected on the four FEC lanes of in consecutive non-overlapping blocks of 8192 codewords.
