NimbostratusAssuming that you haven't configured the priority on the root switch for VLAN 201, you can try this (in config mode):
- non-root switch: spanning-tree vlan 201 priority 40960
- Nexus switch: spanning-tree vlan 201 priority 36864

CirrusI have priority set on c3850 switch that's is why it's root bridge and second c3850 is sencandary root bridge.
This is not an issue about root bridge, it's about STP failover.. even I sent very high cost on 2G link my STP doesn't getting switch to 10G.. you can see in output.
