According to Cisco doc, "NetFlow Aggregation feature allows Cisco NetFlow users to summarize NetFlow export data on an IOS router before the data is exported to a NetFlow data collection system."
I'm trying to configure this feature based on the following requirements:
- Export stats every 5 minutes
- Aggregate the flow based on ports and allow max 2000 entries in cache
- Delete inactive entries every 3 minutes
Here is my proposed config.
ip flow-aggregation cache protocol-port
cache entries 2000
cache timeout inactive 180
export version 9
export destination 1.1.1.1 9999
!
interface GigabitEthernet0/0
ip flow egress
ip flow ingress
My questions are:
1. Do I still need "ip flow-export version 9" and "ip flow-export destination 1.1.1.1 9999"? Are these config for Main Cache netflow only?
2. How do I config "export netflow stats every 5 minutes"?
