Re: [ns] color in nortel diffserv implementation

hi Mandeep,
  thanks for the reply.i went through dsPolicy.cc which does the marking
by setting the codept to the prio_ field of iph in Policy::mark(Packet
*pkt) method.i have added the code
      iph->fid_ = codePt
to this method so that color based on the codepoint can be seen and it
works.i think this will help in distinguishing the packets when seen in
nam.
  thanks.
  Renjish.
