I hope not. You probably mean "10.1.1-1.1-75" (for 30 req/sec) :)

The correct proxy address is 10.1.0.1:
http://www.web-polygraph.org/docs/workloads/polymix-3/#Sect:2
http://www.measurement-factory.com/docs/PolyMix-3/ (Section 3.2)
However, since you are doing transparent redirection, the proxy IP
does not really matter for Polygraph (Polygraph does not know about
it).

AFAIK, Polygraph does not have any hard-coded IP addresses. You should
be fine with 10.1.0.1 or any address that the switch/router can send
WCCP packets to and that does not match any other existing IP.
Good luck,
