ls1021a serdes protocol options SGMII1 and SGMII2 must be configured simultaneously?

[Xi-nanWang]

Based on this tab, there is no option to config SGMII1 only

Your understanding is correct.

THX. By the way，Sgmii1 corresponding to etesc0，Sgmii2 corresponding to etsec1? If it is，does it mean its impossible to config Etsec0 as sgmii，etsec1 and etsec2 as rgmii?

[ufedor]

SGMII1 -> eTSEC1

SGMII2 -> eTSEC2
