    83 This information shows the internal configuration of the "pipes" used to emulate network characteristics,
    84 four lines for each pipe.

     82(Note that your output may appear in a different format, depending on what version of ipfw happens
     83to be installed on your delay node. However, the key information is still available.)

    8585You'll want to make note of the two pipe numbers, one for each direction of traffic along your link.
    8686In the example above, they are 60111 and 60121.
     
    9191The next value shown is the delay, 1 ms in the example above.
    9292The packet loss rate (PLR) is omitted if it's zero, as shown above. If non-zero, you'll see something like '''plr 0.000100'''
    93 immediately before the "1 queues" on the first output line.
     93immediately after the "50 sl." on the first output line.
    9494
    9595It is possible to adjust the parameters of the two directions of your link separately, to emulate asymmetric links.
