Description (partial)

The interface status is in "Unknown GBIC" after rebooting the switch using the command "reload" and while inserting SFP on these ports the link won't come up and the status will become "No X2". Upon removing the X2 the status goes back to "Unknown GBIC" and we see the following error message,
