Flow Control on Software iSCSI physical NICs

[NSITPS]

Hi

I want to enable flowcontrol throught the iSCSI network - How do I enable it on the NICs which are bound to the software initiator?

This is a ESX 4.0 U1 deployment.

Enable TOE, if the NIC supports it, and the NIC is on the HCL for ESX, then that's it. ESX 4.0 will use it and it will be enabled.

I am reasonably sure that flow control is enabled by default on GB ethernet

You can use ethtool to view / change settings on nics.

~ # ethtool vmnic0
Settings for vmnic0:
        Supported ports: [ TP ]
        Supported link modes:   10baseT/Half 10baseT/Full 
                                100baseT/Half 100baseT/Full 
                                1000baseT/Half 1000baseT/Full 
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full 
                                100baseT/Half 100baseT/Full 
                                1000baseT/Half 1000baseT/Full

        Wake-on: g
        Current message level: 0x000000ff (255)

Use

ethtool -A vmnic0 rx on tx on 

to enable flow control for transmit and receive.
