Hi Farhad,

Please look into below links where you will find more details about straight-through, active-active and enhanced vPC topologies.

I don't think you'd be able to send active-active traffic just using straight-through topology. You can use vPCs and bind the 2 straight-through fexs spread across 2 leaf switches for active-active traffic though.

Please find the below link as well where supported topologies between Nexus and fex devices are captured.
