Minimum links with VPC

[CJM]

Hi,

I have three datacenters connected in a ring with 3x10Gbps port-channel each. I'm using a pair of Nexus in each datacenter to connect lines. 

In each DC, two lines are connected to Nexus1, and the other line is connected to Nexus2, and the three of them form a VPC.

I need a minimum of 20G between DCs in order to not overload the connection. So I would like to accomplish the following behaviour: if two of the lines go down (no matter which), the vpc must go down.

Using traditional port-channels with lacp there's a the min-links feature. Is there any similiar feature with VPCs? I haven't find any...

Thanks in advance!!

Not aware of a feature that does that in nx-os but you could use an EEM script that tracks the physical state of the links and if 2 fail or are unreachable shut the 3rd down , as an option

I believe if you check the EEM section there will be similar docs already doing this in IOS to get an idea
