Hi
What i know that Teaming will create a Virtual MAC that represents both NICs and the 745 should not see the real MAC addresses.
If you just telnet to the switch where one NIC of the server is plugged and ping its IP 172.16.4.7,
then run: show arp
Note down the MAC you see, and compare it with what you get, and you can do the same on the switch where the other NIC is plugged.
I'm sure there is something missing here on the teaming, because the 745wl like any other network devices, should not see the real MAC addresses of the NICs, but it should see the Virtual one after teaming.
Good Luck !!!
