Re: [ns] coloring packets ...

[John Mehringer <mehringe@ISI.EDU>]

Packets in ns are usually colored by setting colors to flow ids.  Here
is an example script.

set agent(1) [new Agent/UDP]
$ns attach-agent $node(1) $agent(1)

$ns color 1 "blue"
$agent(1) set fid_ 1

In this script all packets produced by agent(1) will be blue when viewed
in nam.
I think you probably need to do something similar to this.
