In the NetApp and VMWare Virtual Infrastructure 3 Storage Best Practice guide on page 39

It talks about using Flow Control. My setup is this:
ESX HostßàCisco switch in IBM BladeCenterßàCisco 6509 Core SwitchßàNetapp Filers
The guide says to set the items at the end of this chain (ESX host and Filer) to Flow Control Send ON, Receive OFF
The guides says to set switch ports to “Desired” or if that is not available Send OFF, Receive ON
I dug around quite a bit trying to find out what my Flow Control configuration is now and if need be change it to the recommendations. In Filerview I found where to set these. Right now my iSCSI interfaces and my Public Network interfaces are set to Full which I think means that Send and Receive are both ON. A few questions:
1. Do I change both the iSCSI interface and the Public Network interface in the filer to Send ON, Receive Off?
2. Where do you find the configuration of Flow Control on the ESX host? I have dug all over the place and cannot find what my current settings are or how to change them if they are not correct. I am using VMWare’s Enhanced VMXNET adapter for all of my VMs and ESX3.5
3. Since I have two switches between my ESX host and my Filer, do I assume the recommendation is the same for switches (Send OFF, Receive ON)?
