Test without random detect defaults to tail drop when the queue class is
full.
Test1 with random detect enabled weighted random detecion based in
precedence value.
The packets, will not randomly be dropped, the lowest preference tagged
pakets get more chances to get dropped than highest preference packets.
To selectively drop packets, they must first be marked at the ingress or at
any point in the network, so that when the network experiences congestion
those packets get dropped based in the precende value you set.
So in your example, the packets that fall into class "test1" have more
probability to being dropped than packets from any other class.
And within class "test1" the lower preference packets will be dropped more
aggresively than packets with high preference.
