We've seen the same between Juniper and Arista boxes in the same rack 
running at 100G, despite cleaning fibres, swapping optics, moving ports, 
moving line cards, e.t.c. TAC said it's a non-issue, and to be expected, 
and shared the same KB's.

It's a bit disconcerting when you plot the data on your NMS, but it's 
not material.

Mark.
