How to dissable LOMs Flow Control by VC?

[Nima Gh.]

We contacted the Broadcom for disabling flow control of bnx2x LOMs and they told that we must use Virtual Connect for this purpose! How is it possible?

hi Nima,

The setting to disable flow control is not configurable in the current firmware revision for Virtual Connect.

page 33

However you can disable flow control for individual Proliant servers. Check this guide:

hope that helps

Thank you very much, but there is no guide for linux. this documents talks about windows driver! how this should be done in Linux?

Try dropless_fc=1 as a parameter to the bnx2x kernel module.

The Solution: Upgrade the firmware to 2.33 and use set advanced-networking FlowControl= off
