IDSM-2 gives 500Mbps in IPS mode and 600Mbpgs in IDS mode. Bundling 4 IDSM-2 in single chassis gives 2Gbps performance with Sup 32. But the FWSM provides 5Gbps throughput and the Sup 720 supports 40Gbps switching. What is the disconnect here? How do you design your IDSM-2s to support 5Gbps throughput when you have a single FWSM supporting 5Gbps?
