Configuring MLAGs
  
  
    This section provides the commands used to
      configure MLAGs and display information about those configured.
    - 
        To create an MLAG (Multi-switch Link Aggregation Group) peer switch
          association structure, use the following command:
        
          create mlag peer peer_name
          
        
       
- 
        To delete a peer switch, use the following command:
        
                    delete mlag
          peer peer_name 
                
       
- 
        To associate an MLAG peer structure with an MLAG peer
          switch IP address, use the following command:
        
                    configure
          mlag peer peer_name ipaddress peer_ip_address {vr VR}
                
       
- 
        To unconfigure the association, use the following
          command:
        
                    unconfigure
          mlag peer peer_name ipaddress 
                
       
- 
        To configure the time interval between health check hello
          packets exchanged between MLAG peer switches, use the following command:
        
                    configure
          mlag peer peer_name interval msec 
                
       
- 
        To unconfigure the time interval setting and reset the
          interval to the default of 1000 ms, use the following command:
        
                    unconfigure
          mlag peer peer_name interval 
                
       
- 
        To bind a local port or LAG (Link Aggregation Group)
          to an MLAG specified with an integer identifier, use the following command:
        
          enable mlag port port
            peer
            peer_name
            id
            identifier
          
        
       
- 
        To disable a local port or LAG from an MLAG, use the
          following command:
        
                    disable
          mlag port port 
                
       
- 
        To set a preference for having a fast convergence time or
          conserving access lists, use the following command:
        
                    configure
          mlag ports convergence-control [conserve-access-lists | fast]
                
        
          
Note   
Executing the 
refresh policy
            command with MLAG configuration may result in health check hellos not reaching the CPU.
            To avoid MLAG peer connectivity disruption, you can either execute the 
disable
              access-list refresh blackhole command or temporarily increase the peer hello
            interval to a large value (for instance, 10000 ms) and reset it back once refresh policy
            is complete.
 
         
       
- 
        To enable or disable MLAG linkup isolation, use the following command:
        
configure mlag ports
          link-up-isolation [on | off]
