Create Trace

[Massimo Pegorer <pegorer@tvdsp2.vim.tlt.alcatel.it>]

Hi!

I'd like to trace only dropped packet on a link
so I've used (n&d p.100):

[...]
set file [open drop.tr w]
$ns create-trace Drop $file $n(1) $n(2)
[...]

It creates the drop.tr file but it's empty,
while from nam (or from the trace-all file)
it' s evident that there are some dropped
packets!?

Thanks in advance for help,

Max
