Are you using Intel pro 1000 PT (ExPI9400PT server adapter or Intel Quad port bypass server adapter (this one support bypass mode)
If it is expi9400PT , then I don't think it support bypass.
Thank you for the reply.
I'm using the intel pro/1000 pt quad port bypass adapter, EXPI9014PTBLK.
Can i ask as well what is the difference between PT and AT. This is because i did a check with "lspci -vvnn" to show the device connected and it state there AT instead of PT. The packaging I have with me states PT.
This is the result from lspci -vvnn:

sorry, got no idea about the difference..
But do you know how to configure the bypass mode?
This is Doug from the factory. The bypass functionality information on our bypass adapters are available via the premier.intel.com support service, or via the distributor or extended sales force team member that sold your organization the card. Bypass adapters were designed to be used by development partners and not for general end user use. As such the support model is unlike our normal adapters. If you don't have access to premier.intel.com and/or the company that got the card, please private e-mail me and I'll see what I can do for you.
Hi! I have the same problem, could you please help me? I bought the intel quad bypass, and I don´t find any information on the website. I want to use the device with a snort in Linux. Thanks in advance!
