Intel I350 NIC Teaming Issue

[GButc]

Afternoon,

When I team the Four Ports on an Intel I350 Adapter together in Static or Dynamic Mode the Ports on the Network Card drop connection within 1 minute periods and then gets connection again.

I have removed the team and the ports stay on fine, but when teamed together they start losing connection and Event Errors:

E1rexpress

iANSMiniport

Basically using the 4 ports for LACP for our Backup Services for this server, but if the NIC Connects are flaky then the Backup Job fails!

I've tried googling this but keep hitting the same brick wall.

The server is Windows 2003 R2 x32 and the Intel Drivers: 12.7.28.0

Teaming Setup as: IEEE 802.3ad Dynamic

Any help on this would be great.

Many Thanks

Gerard

Hello Gerard

I have been asking for basically the same question re IEEE802.3ad dyn agg lacp issue month ago. No luck.

Moreover more than hundred posts via email chain with intel support. No luck.

They don't know the answer

One Q: do you have the heavy traffic load once the adapter goes off-line?

We have the same issue with our Commvault Mediaagent that use Intel Gigabit ET Quad Port server Adapter in a LACP team of 4 NICs.

It happens when traffic is getting high.

Proset Version 18.5.54.0

Driver version 12.7.27.0

OS: Windows 2012 with latest patches

I think it has something to do with the settings

Check Time or Load Balance Refresh Rate, maybe somebody from Intel could reply?

Just installed driver version 18.6 but still the same issues.

Nics are disconnect at random.

Any resolution on this issue? Having the same issues with the I350 ET Dual Port. Disconnects/Freezes during high traffic and Server 2008 also throwing out Event ID 2012 SRV in event log all day during peak traffic. Installed the latest drivers two weeks ago. Event Log Warnings 11, 13, 14, 27, but normally overnight and not during the work hours.

Hi Gerard butcher,

I just want to check if you are using PROSet version 18.3 for the teaming? https://downloadcenter.intel.com/product/59063/Intel-Ethernet-Server-Adapter-I350-T4 Intel® Download Center
