We have 3 PVC's running thru a 7513/8540 to our Internet connect. We have 6 core nodes all running thru this. Some flows coming from vlans on other 6500/msfc's were only showing uni-directional flows thru the 7513. When we enabled flow export on the 6500's to the same flow collector box we got a lot of dupes etc, but we also got the missing side of the uni flows.... We have talked to TAC and they believe that it's a flow bug in 12.0.5t since we cannot move to 12.1.7 yet on this router we will have to wait and see.

I haven't seen that problem on a 7500 nor on a GSR running 12.0(15)S we just have "ip route-cache flow" on the ATM major interfaces and I believe its working correctly. Same for the Gb interfaces with 802.1q VLAN sub-interfaces configured. Did you determine this by comparing to if(In|Out)Octets? What IOS version(s)?
