LACP with Balance-TCP Taking full advantage of bandwidth provided by multiple links to upstream switches, from a single VM, requires dynamically negotiated link aggregation and load balancing using balance-tcp. Nutanix recommends dynamic link aggregation with LACP instead of static link aggregation due to improved failure detection and recovery.

Naah, Nutanix doesn’t recommend balance-slb because of the multicast traffic caveats. To combine the bandwidth of multiple links, consider using link aggregation with LACP and balance-tcp instead of balance-slb. Don’t use balance-slb unless you verify that the multicast limitations described here aren’t present in your network.

Yeah and for the redundancy part, I know balance-tcp fails back to active-backup in case of a link failure. I'm not sure if the same is true of balance-slb
