we also utilize VSS/MEC in some of our cisco environments with LACP and this works fine on the netapp filers without any special configurations.

This works fine, and is a pretty popular setup.. It's just like a normal etherchannel or LACP setup.. in fact, you likely won't have to touch the filer configuration at all.

We already use bonded/trunked ethernet from the NetApp to a switch. That's fine.
We are planning a network upgrade, which gives us a chance to do this bonding/trunking to a logically linked pair of switches (Cisco 3750E) that operate as a single virtual switch, using "MEC". (The theory is that if a switch in the MEC-pair fails, the bond/trunk link continues working through the other switch, albeit with degraded throughput.)
Does anyone know whether MEC does/doesn't (will/won't) work? Is there anything MEC-specific that needs to be done in NetApp? Issues? (Other questions I should be asking? Etc.)
Pointers to existing information would probably be fine.
Thanks in advance.
