Card is in a Dell PE M620. Seeing multiple cases where trying to create a static link aggregation is failing with the message "All device in a Static Link Aggregation team must be capable of running at the same speed. At least one device in the team is not capable of running at a lower speed."
This message appears even when trying to create a team with just one adapter. Both the switch ports and the NICs are set to 10 Gb Full. Operating system is WIndows Server 2012R2 but has also happened on Server 2008R2,
Resolved - don't know if it's related to anything on the switch side, but the issue does not occur when running the Intel Software version 20.3. The affected servers had been upgraded to 22.7. Rolling back the version resolved the issue.
