All the IDS's in the Cisco range except for the blades have two Nic's in them, you should see this o the 4230.
The one in the slot is the promiscuous card i.e. the sniffer and the on-board nic is the one with the TCP/IP stack loaded on it. So you connect the promiscuous nic to the switch and I assume configure it as a monitoring port, then connect the other nic to either your internal network (at least this is one way of doing it).
The CSPM should be connected to your Internal Net. The first thing to do is to ensure that the CSPM can ping the sensor to ensure network connectivity. Once this is done you then go into the CSPM and configure a new sensor using sensor wizard, provided you do it right the CSPM will poll the Sensor and establish a communications stream between, I believe the postoffice daemon on the sensor and the post.office service on the CSPM (UDP port 45000 by default). After your sensor has been set-up the CSPM and sensor will always communication on udp port 45000.
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
