What is the easiest way to determine what southbound (IO Module) and northbound ports / interfaces (Nexus 5K, MDS 9000) are connected to what FI ports, without performing a physical inventory?
Something to gather the similar to the:
FAB A
2104XP Port 1/x <> 6120XP Port 1/x
6210XP Port 1/x <> 5010 Eth1/x
6120XP FC Port 2/x <> MDS91xx fc1/x
etc ...
Thanks,
Dan

Fex Network Port
The 2104XP IO Modules also have 4 Network Interfaces (NIFs / Fex Uplinks) which connect to its upstream Fabric Interconnect.

I think Walter covered downstream fairly well.
If if you are running 2.2.4b or later you can use the neighbors in the GUI once you have enabled the info policy. See here: http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/sw/gui/config/guide/2-2/b_UCSM_GUI_Configuration_Guide_2_2/configuring_the_fabric_interconnects.html#concept_B9454968E36347AAB281C752B9624870
If you prefer CLI you can use "show cdp neighbors" in NXOS context to see what port you're connected to on the FI and what remote device and its port is plugged in for Ethernet.
I I can't recall, but I am fairly sure you won't see FC info from the MDS in CDP neighbors, so you will need to issue some FC commands from the FI NXOS shell too. I would just do a "show flogi"

Thank you Steven and Walter for the information. Exactly what I needed.
