I have a Supermicro AOC-STGN-I2S dual SFP+ installed in Lenovo m920q. Port 0 is connected to 10 Gbps switch port and Port 1 is connected to 1 Gbps switch port.
Port 0 works fine in Pfsense but not port 1. No carrier status for Port 1. At the switch, the port is set to negotiate at 1 Gbps.

ifconfig -vvvm ix1 returns

Code:
ifconfig -vvvm ix1
ix1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

Tried to change to 1Gbps but it failed to. How can I force the port to negotiate at 1Gbps?

Code:
ifconfig ix1 media 1000baseTX

ifconfig: SIOCSIFMEDIA (media): Device not configured

I've got the base-T version in use here ( aoc-stgn-i2t - x540 equiv ) under esxi, one porr to a 10gbe port on the switch and one to a 1gbe (running opnsense virtualised - the 1gbe port is to connect to my fibre ONT) - no problems at all negotiating the lower speed

what you're seeing could be a FreeBSD driver issue - one of the reasons I switched to running OPN virtualised was because of issues with the FreeBSD ixgbe driver. I'd suggest boot a 'live' linux distro off UISB and see if the 1gbe link negotiates ok running Linux
