Link Aggregation and Software-Controlled
Redundant Ports
  
    If you are configuring software-controlled redundant ports and link
      aggregation together, the following rules apply:
    
      - You must unconfigure the software-controlled redundant ports before
        either configuring or unconfiguring load sharing. 
        
- The entire LAG (Link Aggregation Group) must go down before the
        software-controlled redundant port takes effect.
