[j-nsp] [c-nsp] Stange issue on 100 Gbs interconnection Juniper - Cisco

Things I would look at:

 * Has all the connectors been verified clean via microscope?

 * Optical levels relative to threshold values (may relate to the
   first).

 * Any end seeing any input errors?  (May relate to the above
   two.)  On the Juniper you can see some of this via PCS
   ("Physical Coding Sublayer") unexpected events independently
   of whether you have payload traffic, not sure you can do the
   same on the Nexus boxes.
