I have two 6500 switches/routers trunked to each other serving various\ndevices. The two switches are installed for the purpose of redundancy\nand same VLANs are configured on both. My question is related to\ndeploying IDSM-2 blades in this environment. Can I just use single\nblade in one switch and still be able to monitor desired VLANs traffic\nthrough VACL or SPAN/VSPAN/RSPAN or do I need two IDSM blades; one in\neach switch. Has anyone deployed IDS in this environment and what are\nthe benefits of deploying 2 (one is each) versus 1.
