Hi,

How can I monitor ifq in a lan? 

I tried to use 
$ns attach-fmon [$ns link $n0 $Lan] $fmon
where n0 is a node on the lan, and Lan is the LanNode for this lan.

but it gave me the error:

_o75: unable to dispatch method attach-monitors
    while executing
"$lnk attach-monitors $isnoop $osnoop $dsnoop $fm"
    (procedure "_o3" line 5)
    (Simulator attach-fmon line 5)
    invoked from within
"$ns attach-fmon [$ns link $n0 $lan] $ifq_fmon($i)"
    (procedure "build_topologyB" line 37)
    invoked from within
"build_topologyB"
    (file "test91.tcl" line 795)

Can anyone please give me some suggestions? Thanks a lot.

Huiwen
