I have to be over looking something dumb here but I can't figure it out.
The fex is set up properly and is communicating to the Nexus 5548 without issue. There are a few other fexs connected as well.
The interface config is bare bones at this point:
interface fex100/1/1
switchport access vlan xx
spanning-tree port type edge
no shut
I have tried to plug other devices into the port and no link lights will come up. No errors are shown in the log. I have connected to the server via its Ethernet port from a directly connected laptop and its link lights come up no problem.
The vlan is already on the switch as well.
A show interface shows that zero traffic has crossed the link.
If there is any other information I could provide please let me know.

I found out the upstream 5k was in a pair so I needed to make the interface config change on both 5ks. Problem solved.
