Having problems getting the Netflow analyzer to detect any Netflow traffic. I have a wireshark capture from the monitoring station so I know the record traffic is making it to the end device. However, all of the packets are "Bad Checksum" or not template found. Below is a sample of the configuration:
flow record NTA
match ipv4 tos
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
match interface input
match flow direction
collect counter bytes
collect counter packets
collect interface output
!
flow exporter NetFlow-to-SW
destination x.x.x.x
transport udp 2055
!
flow monitor NETFLOW-MONITOR
exporter NetFlow-to-SW
cache timeout inactive 10
cache timeout active 60
record NTA
!
Then I have the NETFLOW-MONITOR added to the interface that I would like to capture.
Any thoughts or examples of this working on other (4000 Series ISR's)
Thanks.
