VLAN issue with latest NIC Driver

[Technology Helpdesk]

We currently have multiple VLANS setup on a Cisco 6500 and a DL360 g4p. When we upgrade to the latest support pack (7.90a) with firmware some of the VLANs are not accessible. We've tried this in two different environments and we get the same issue. The NIC model is a NC7782.

Has anyone seen this or does anyone have any documentation they could point me to on what may have changed on the latest NIC driver VLAN config wise?

Hello,

Try updating the NIC firmware ALONE,
then, upgrade the Drivers.

{All this is after PSP 7.90}

Also, Disabling TOE Helps resolve MANY issues in NIC performance/Teaming Issues.

James,

Thanks for the quick response. I don't see anywhere for me to disable the TCP Offload Engine under the NCU. Is there some place else or a command I should use?

Thanks again,

Travis

James,

Is there anything else I can try? I've tried both of those and I'm still not able to access some of the vlans.

Thanks again for the help.

Reading this Again... "When we upgrade to the latest support pack (7.90a) with firmware some of the VLANs are not accessible."

I hope U have Updated the FIRMWARE first, then the Latest Drivers; Then Apply the Latest NIC Teaming Software .. if any;

James,

I applied the firmware and then the support pack which applies the latest drivers and NCU. This is for Windows 2003 R2 SP2 and I know that HP has had issues with SP2 and their NIC drivers.

Yes Travis, PSP does installs them;
However, It may be worth to install them separately; I have seen cases when Applying them separately solves issue; U might wanna try it too, in case u haven't :

NCU

Broadcom drivers
