[ns] current status of Csma/Ca and Snoop ?

[Benyuan Liu <benyuan@cs.umass.edu>]

Hi,

 I am having problem with Csma/Ca and Snoop in ns. I know this is an old
problem, I read all the related messages in the archive. It seems I am
having the same problem. When I use Csma/Ca (running mac-test.tcl), I got
the following error.

Can somebody tell me the current status? Or if you know the trick to use
Csma/Ca or Snoop?

Thanks.

Ben

The error message looks like:
----------------------------------------
invalid command name "Mac/Csma/Ca"
    while executing
"Mac/Csma/Ca create _o26 "
    invoked from within
"catch "$className create $o $args" msg"
    (procedure "new" line 3)
    invoked from within
