I'm super new to Nexus, so I'm not really sure how to troubleshoot this. I did a quick search and found that this is related to DCBX TLVs in LLDP, which we apparently shouldn't be getting on a regular ethernet port. I'm pretty sure this is just a regular ethernet port. (Like I said, I'm pretty new to nexus. lol) I wonder if the following output indicates that we are receiving and sending DCBX TLVs in LLDP. If so, it sounds like the interface will go into err-disable state if the server stops sending ACK frames.
# show lldp dcbx int e1/17

This is the first time we've run into this. Any idea what might really be going on?
Thanks!
