Hi Luis, currently this feature is only supported on EOS for specific HW.

I don't see any roadmap for that in EXOS.

If you could change the SLB config on the servers to an NLB (Network Load Balancing) if using microsoft we could use an NLB kind of solution.

Depending on your topology, you can have a look at the Health Check Link Aggregation feature (p.271 of 16.1 User Guide). I never really used it, but that might help you.

Another approach could be via ACL. You can create a "sort of" SLB if the servers' IP can be masked correctly. Here's an example of such ACL (you would have several rules like that):

entry r11 {
    if {
        source-address 0.0.0.0 mask 0.0.0.7;
    } then {
        redirect-port-list 1:1;
    }
}

entry r12 {
    if {
        source-address 0.0.0.1 mask 0.0.0.7;
    } then {
        redirect-port-list 1:2;
    }
}
