I am at a standstill, I am supposed to upgrade the code on the companies N7K's and the assorted downstream equipment from the 4.x os to at least 5.1(2). I don't see any specific reference to whether this code will or will not support it. Ok, then if it still does not. Will the 5.2 code support it? If so is there a release date? This is causing many issues staying on the 4.x code with respect to Older unix systems and the lldp issues encountered.
