[help] having error in SetQueue

[DUO CHENG]

Hi all,

I'm receiving a error message like this:

• msg="Invalid attribute set (MaxPackets) on ns3::DropTailQueue<Packet>", +0.000000000s -1 file=../src/core/model/object-factory.cc, line=78

and I think this is the line of code causing the error:

•  pointToPoint.SetQueue("ns3::DropTailQueue<Packet>","MaxPackets",StringValue("1000p"));

How should I modify this? I'm using the latest version of ns3. 

Thanks!

Try:

pointToPoint.SetQueue ("ns3::DropTailQueue", "MaxSize", StringValue
("1000p"));
