We have DCX-4S switch with two 48 port slots. We have been seeing CRC errors with good end of frame errors. Support have requested we run serdestunemode for 24 hrs, which we have done but we still have been getting a few of the same errors from one particularly address. Support are still looking into it
Anyone had this issue previously as we are seeing performance issues in the SAN
Are you seeing those on the backplane ports or the user ports? g_eof means the error has not been detected before, i.e. it's not a forwarded CRC error.
How many ports do you see CRC_g_eof in?
As Christophe asked, are these ports User ports or Backplane?
What's connected to these ports?
