Has anybody used MSM IPS for sniffer-like tracing of IP addresses?

We have a need to see any traffic that involves certain subnets, external or internal, in a network where we have IDS, not IPS.  This traffic does not trigger  intrusion events that MSM will detect. We could use an ACL to direct this activity to a syslog server, but then we lose any intrusion event data in McAfee.  I have heard this has been done with UDS events but it would be helpful to have some guidance from anybody who has done this.  Thanks.

Re: Has anybody used MSM IPS for sniffer-like tracing of IP addresses?

I'd like to be able to do that as well.  I've attempted to create a UDS with fixed-field values for the IP addresses that I needed to monitor but there is a limitation of ten values which didn't cover my list.  You can increase the limitation to 50 but I don't know if that has performance consequences or not.  I don't know why the limitation is so low.  We used to watch large ranges of IP addresses with a competing sensor without any problems.

Thanks for the response, Bob.  Yes, I know of 2 of their competitors in IPS/IDS that make this sort of tracing comparatively easy for ranges of IP addresses if not CIDR-defined ranges.  The MSM monitors more networks than we have sniffers or sniffer access.
