How to Enable flow control on VMware ESXi 4.1 and Persist the config across reboots

Last Modified: 2012-08-15
Hi All,

I intend to enable flow control (along with Jumbo frames) between my VMware ESXi hosts and my Cisco 3750G switches in a multipathing iSCSI setup.

VMware version is 4.1, ESX Hosts are HP Proliant DL 380 G7 servers with Broadcom NICs

1, How do I configure flowcontrol transmit on (send on) and receive off using the ESXi CLI
2, How do i save the above configuration to persist across ESXi host reboots?

All the above instructions should be provided step by step.

3, If I am using etherchannel between Cisco 3750G switches and my storage appliance (NetApp FAS2020) is it advisable to confiure etherchannels also between my VMware ESXi Hosts and the Cisco Switches? If yes, which type of etherchannel (mode on or mode active ) should be configured?

VMware vSphere 4.1 does not support lacp etherchannels (I am told) which is what I have btn NetApp and Cisco.

Each ESXi hosts has two NiCs for iSCSI traffic connected into separate Cisco switches in a cross-stack.

Simple straight forward asnswers would be most appreciated.
