I wrote a tcl script to monitor individual flow, here is the code :
set fmon [$ns makeflowmon Fid]
set ecLink [$ns link $e1 $core]
$ns attach-fmon $ecLink $fmon
set fclassifier [$fmon classifier]
set flow1 [$fclassifier lookup auto 0 0 10]
set parr [$flow1 set parrivals_]
puts "flow: $parr"
But it always shows me the wrong messege as the following :
invalid command name ""
while executing
"$flow1 set parrivals_"
invoked from within
"set parr [$flow1 set parrivals_]"
(file "test_Null_mon_flow.tcl" line 185)
Someone please gives me a hint or tell me how to solve it ?
Thanks
