VMware Esxi 5.5 Enhanced LACP LAG with Nexus Switching plus NetApp LACP LAG
* Storage is NFS Traffic with Jumbo Frames . NetAPP CDOT
* Assuming Nexus is setup properly
* NFS Traffic layer 2 no gateway required
* ESXI Server can ping NETApp lifs by jumbo
* NetApp cannot ping back Esxi Hosts on Jumbo
On the Nexus Switches , what is the recommended settings for the ESXi Hosts ? I don't necessarily need the command set but recommended settings
IE : Turn off Spanning Tree ?

Title ping command to some destinations fails with large packet size
The ping command fails on certain destinations with packet size larger than 1472 bytes and fragmentation disallowed.
