Configuration Examples for NetFlow Lite
Example: Configuring a Flow
When configuring a flow, you need to have the protocol, source port, destination port, first and last
timestamps, and packet and bytes counters defined in the flow record. Otherwise, you will get the following
error message: "Warning: Cannot set protocol distribution with this Flow Record. Require protocol, source
and destination ports, first and last timestamps and packet and bytes counters." Note
This example shows how to create a flow and apply it to an interface:
Switch#
