Yah, "problem with Cisco", been there done that *grumble* *mumble*.  

Do the server guys mean to have a "failsafe" configuration with each NIC
one connected to a different switch (in active/standby or in
outgoing-loadbalanced mode), or do they want 802.3ad link aggregation
(aka LACP), with both interfaces connected to the same switch?

Might be worth getting that part of the setup straigt before hunting
after lost packets and brooding over retransmissions.
