Hi, yes that's one of the problems. I couldn't set media to 1000baseLX and ifconfig ix0 media only showed me autoselect, even when BiDi was inserted into nic. Maybe that's problem with x552 but i didn't have x520 near me at that time. Good thing is that BiDi sfp's arrived and I will play with them.
