Problem getting vlans working over Dell N4000's SFP+ connections

Hi -

I have 2 dell switches. N4032's 10g. We just took over a small office across the street and had fiber ran underground to connect the two offices.

The fiber connections works well for them to communicate - no problems. (24 strands were ran) but i tried to get the backup network working over the Vlan through port 4 SFP+ and its not liking that - cannot talk to anything over there on the backup vlan. I then tried to bind the IP subnet to the Vlan 99 (backup network) to see if that would solve it - it still does not

Here is the running config. They mirror eachother on both sides.

Can anybody think of what i have incorrect on here?
