Netflow inaccurate traffic values
The situation I have is I have recently bought the license for NetFlow plugin, now I added three to 5 devices testing the monitoring, and seems there is an issue in traffic values, IN TRAFFIC and OUT TRAFFIC
I have ASR 1002, I applied different netflow configurations
The one that didn't work which is the
flexible,
I didn't get any devices on NetFlow
flow exporter ME-FE
destination 10.20.116.67
transport udp 9996
flow record ME-REC
match transport tcp destination-port
match transport tcp source-port
match transport udp destination-port
match transport udp source-port
match ipv4 destination address
match ipv4 source address
collect counter bytes
collect counter packets
Configuring Flow Monitor
flow monitor ME-MON
record ME-REC
exporter ME-FE
cache timeout active 1
cache timeout inactive 10
interface serial0/0
ip flow monitor ME-MON input
The one that worked is the
traditional which is the old one, which I don't mind, but it displays in accurate traffic in and out values, please see screenshot, knowing that these interface receive traffic near 3 mb and it is displaying low values
