How to add ports to VDs Switch for LACP

Hi All,

I have created vDS switch on vCenter 5.5 windows 2012 R2 server.

I created two LACP Group with out issues each with 8 ports.

When adding third one I am getting error " The link aggregation group will not have any ports associated wit it. This group cannot be used for backing network traffic.

Not sure how to add ports for LACP.

Thanks,...
