We've been upgrading the IOS to NCS 5508's here and we are getting copper ports randomly not coming back up after the restart. Moving the SFP to a different card on the chassis will bring it back up and the ports themselves don't seem to be bad (other optical sfp's will work fine). Was curious if anyone else was seeing this and/or if anyone had a solution to it other than just moving the port. We have cisco cases open as it seems we may have discovered a new bug...er feature.
