@luca.s4,

You can hard code that logic into the port by case function, but it's a lot easier to just add another queue like Jörg suggested. This is an example of a way you could hard code it. (It's not that efficient.)

int outPort;
if(item.MyLabel1 == 1)    {
    outPort = bernoulli(50,1,3,getstream(current));
    if(!opavailable(current, outPort))    {
        if(outPort == 1)    {
            outPort = 3;
        }
        else if(outPort = 3)    {
            outPort = 1;
        }
    }
}
if(item.MyLabel1 == 2)    {
    outPort = bernoulli(50,2,3,getstream(current));
    if(!opavailable(current, outPort))    {
        if(outPort == 2)    {
            outPort = 3;
        }
        else if(outPort = 3)    {
            outPort = 2;
        }
    }
}
return outPort;
