I have a problem... I'm using a AIP-SSM20 with 6.1 version and IOS 12.4(6)T11 for building DTM (Distributed Threat Mitigation) with CS-MARS 4.3.5. I followed the document "Technology Preview: Configuring Distributed Threat Mitigation with Intrusion Prevention System in Cisco Security MARS" but I didn't have sucess. I would like to know if someone can building DTM with sucess? They could give me a tip???
