[Tuexen Michael] This value is used as the TOS field in the IP
packets.
See RFC 1349 for the specific values. The one here is choosen only for
demonstration and has no specific relevance for the application.

[Tuexen Michael] You need a path failure. So one possibility
is to plug out one of your (multiple!) network cables. The other is
to have
a WAN emulator between your hosts and change the configuration
of that emulator in a way that the emulator drops packets of one
path. For WAN emulation you can use DUMMYNET which is part of the
FreeBSD.
