queue dropping

[Imed Ben Hmida <Imed.Ben_Hmida@sophia.inria.fr>]

Hello ns-users,

I implemented a new link and queue classes, and I found the following
problem:
The dropped packets in the new queue aren't traced into the trace file:
In the trace file, there are no dropping events , however, enque and
deque events to that queue are traced.
I am sure that there are packets dropped because in my script, I send
more than the link capacity.
The following command exists in the new link trace procedure,too.

set drpT_ [$ns create-trace Drop $f $fromNode_ $toNode_ $op]

Is there anything I am missing ?
Any help is very appreciated.

Regards.
