Sample NetFlow Enabling Schemes

Enabling NetFlow on a per interface basis is not supported on a Catalyst 4500 switch.
Note
This example shows how to enable NetFlow globally:
Switch# configure terminal
Switch(config)# ip flow ingress
This example shows how to enable NetFlow with support for inferred fields:
Switch# configure terminal
Switch(config)# ip flow ingress infer-fields

Autonomous System Configuration
This example shows how to configure an autonomous system aggregation cache with an inactive timeout
of 200 seconds, a cache active timeout of 45 minutes, an export destination IP address of 10.42.42.1, and
a destination port of 9992:
Switch(config)# ip flow-aggregation cache as
Switch(config-flow-cache)# cache timeout inactive 200
Switch(config-flow-cache)# cache timeout active 45
Switch(config-flow-cache)# export destination 10.42.42.1 9992
Switch(config-flow-cache)# enabled
