Configuring Flexible NetFlow
This example shows how to configure a flow record:
Switch(config)# flow record
Switch(config-flow-record)# description record to monitor network traffic
Switch(config-flow-record)# match ipv4 destination address
Switch(config-flow-record)# collect counter packets
Switch(config-flow-record)# collect counter bytes
Switch(config-flow-record)# end
This is an example of output from the show flow record command:
Switch# show flow record
