I have a single board computer with two I210 adapters each connected to a different switch. The adapters are in an ALB team with RLB enabled. Only one adapter is active and connection requests that come to the other adapter from the other switch fail.
Is there a way to make both adapters in the team active?
Thank you for posting in Intel Communities.
Connecting to different switches is not a supported configuration for ALB \ RLB.
Please share additional details of your intended setup. We might be able to help you look for other options.

Thanks for your reply.
I have continued to experiment since posting and am currently working with Switch Fault Tolerant teaming. I have an enclosure with three single board computers and two unmanaged layer 2 switches. An application on computer A needs to connect to applications on Computers B & C. The app on computer A only supports a single IP address for each of the target applications. The two external devices may be workstations or managed switches.
I am trying to configure teaming on two adapters on computers B & C to provide redundancy in the event of cable, adapter, or switch failure.
The problem I am having seems to be the state of the teamed adapters which seems to be dependent on whether the two switches can communicate. If I add a connection between switch 1 and switch 2 or add two external switches with a connection between them, I get the desired results. If there is no connection between the switches, one adapter in the team displays as active and the other as inactive. It appears that some of the time the connection request from computer A comes to the inactive adapter on computer B or C and fails and there is no attempt to try the other path.
Is a connection between the switches required for teaming to work (when there are no failures)?
You can try to manually set the "primary" adapters on the Team in computer B and C to avoid computer A from connecting to the inactive adapters. This setting is found in the "Modify Team" under the "Settings" tab of the Team advanced properties in Device Manager.
Assuming connection to Switch 1 is your active link, Computer A, B, and C will communicate through Switch 1. If Switch 1 fails, The Teaming software would detect link failure and activate the adapter connecting to Switch 2.
Hope this helps.

Thanks for following up.
Initial testing seemed to work. Team type is Switch Fault Tolerant and Primary adapter is set. Unfortunately my test unit is tied up for a couple of weeks so I haven't been able to test further. I hope to have it back my mid-November and plan to test further. No further assistance required at this time.
My development unit has been unavailable for a couple of weeks which has delayed by response.
The Intel I210 Ethernet Adapters are installed on Curtiss-Wright Single Board Computers. The only identification I have been able to find is the "I210" which shows up in Windows Device Manager. I don't see anything that includes the "-T1".
