    Is this setup possible ?

                    |                                     |
                    |port4                           port3|
              +-----+----+                          +-----+----+
              |          |port2       ISL      port2|          |
              | switch A +--------------------------+ switch B |
              |          |                          |          |
              +---+--+---+                          +-----++---+
             port2|  |port1                           port1|
                  |  |        eth0 +-------+ eth2          |
                  |  +-------------+       +---------------+
                  |                + host1 +
                  +----------------+       + 
                              eth1 +-------+
    

    On host1 I want to achieve:
    1) high throughput with bond0 (interfaces eth0 and eth1)
    2) high availability with bond1, mode active-backup on bond0 active and eth2 backup

    Is this setup possible with the bonding driver ?
    I did some experiments and it turns out bond1 doesn't work along with bond0.

    I'd love to see any input on this one.

    You only need bond0 with eth0-eth2 as slave running on mode 4.

    configure port1 and port2 on switch A with LACP group. You will get 2 aggregators. One has 2 ports and the other has 1 port.

    If you use bonding v3.5.0 or higher, the 2-port aggregator will be active.
