I've tried the line card in at<br>least slots 1 and 2. I've rebooted the XMRs. I've used at least three<br>different devices on the other end of the cable, of two different types<br>(servers with Intel NICs and Calix E7s switches). TAC had us RMA one<br>line card, which didn't help. I have tried with a blank config on the<br>XMR and just enabling those ports (e.g. "int e 1/20" & "enable").<br><br>I have not done much, if any, testing on older software versions.
