Edgerouter X-SFP Not working

$

Hi all - Question for the masses.  I have a new Edgerouter X SFP and it is working great all except one little thing - I can't seem to get the SFP port to behave properly.  The setup right now is eth0 is the FiOS WAN connection (Straight to the ONT), and then i have eth1-4 set and any of them can connect successfully to my Cisco switch and link up fine.  (There is no trunking or anything going on here - just a straight link. 

 

I admit I did use one of the wizards to set up the router as it is my first one I've set up - here is my issue:

 

I bought a compatible SFP (TP Link - it was on the compatibility list) for the Edgerouter, and the proper fiber for it as well.  I connect the router to my switch and I see a link and *some* activity on the link, but the switch reports it as down/down.  FYI the switch SFP is a genuine Cisco switch SFP.  I can recreate this with a Cisco 3560E, and two different 2960 switches.  I can link each switch to each other fine with any of the SFPs, so I can't say the SFP or the switch is the issue.  

 

Has anyone seen this?  Do I need to do something to tell the router to treat eth5 (the SFP slot) the same as the other eth1-4?

 

Thanks!
