Tool/software:

WE are using DP83867ISRGZR PHY in SGMII mode anneed to configure it using straps to be in auto negotiation off and 1000Mps SPEED .USING THE RX_CTRL strap we define auto neg to disable and using LED0 strap we define SGMII mode

it seems that it connected to host in 10Mbs only

what do i need to do in order to make it run on 1000Mbs?

    Hi, 

    There is no way to strap to disable auto-negotiation and fix to 1000M. As IEEE 802.3 specification does not specify fixed mode in 1000Base-TX, we recommend to use auto-negotiation and advertise 100/1000 for most robust application of the PHY. 

    Best,
