looking up MAC addresses of ESX NICs in a network switch

I'm struggling to identify to wich ports on a Ge switch a new ESX host has been connected.
First, I checked esx.conf to identify each virtualMac for each nic, then I asked the network gurus to check them out with fdb. Weirdly, not all the MAC's are in the forwarding db. My next try is to put all the nics as uplinks in a vSwitch, and enable nic teaming with beacon probing: I think the beacons broadcasts will update the fdb for each MAC in the switch: will it work?!? Beacon probing is explained in this article.
