I have a few people running on various ISR platforms with 15.0(1)M4 code sending netflow (not flexible netflow) to our collector. We are getting most of the data, but missing either in data on some or out data on others. We have ingress flow on both the WAN and LAN interfaces configured, which normally gives us all the data. Just started running into this issue when we hit the ISR's with this code level. Anyone know if there is a code bug or platform/IOS conflict?
