Is it true that both the csc-ssm and aip-ssm modules can't co-exist in the ASA5500 device at the same time??
One more question is there are sample config/example on the cisco site using the intra-interface keyword command involving NON IPSEC TRAFFIC
Yes, csc-ssm and aip-ssm modules can't co-exist in the ASA5500 as only 1 slot is available to install them. You have to choose one.
See the slot availability at:
ASA5505 & ASA5550 - no slot for csc/aip
ASA5510/20/40 - 1 empty slot each
