We have a stack of 3750s for our core switch. I am looking for software to monitor all internal network traffic.
Anyone know of anything?

Trippi- I don't believe the 3750's support netflow exports. You could always create an access-list to capture all traffic on the SVI and syslog/grep what your looking for. ;)
ip access-list extended FLOWCAP
permit tcp any range 0 65535 any range 0 65535 log
permit udp any range 0 65535 any range 0 65535 log

MRTG, Cacti to monitor bandwidth usage
ntop to monitor traffic patterns and per-protocol break-down.

Will ntop give me session information?
Such as source/destination, etc.?
