I need to figure out the number of active TCP connections on my network at any given time. The trouble is I don't know what show command to run to display this information. I'm looking on my 7606 edge router.

I've tried "show tcp statistics" but I don't know how to read the output and Cisco's documentation doesn;t really clarify.
 
A router isn't going to show you how many TCP connections are flowing through it unless you enable a stateful firewalling process (CBAC, ZBF, etc), which wouldn't necessarily be recommended - also, I don't think the 6500/7600 supports it.
 
show ip cache flow

should get you what you need. but more usable info would be to setup netflows to export to a collector, then you'll be drowning in info ;)

Suprisingly show ip cache flow was mostly empty except for the Pkts column.

I thought this might come down to a Netflow export. It's probably time we actually start doing that.
