Hi,

Have a look at the config guide:

These config examples are mainly for sup-7 and 8:

Can you post-show modules to check is that supported or not.

Hello @BernardNdale ,

you have a Sup 6-E the following link provided by Reza explains that Flexible Netflow  is supported on Sup 7 or Sup 8

see

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4500/XE3-8-0E/15-24E/configuration/guide/xe-380-configuration/fnf.html

So I am afraid Netflow at least Flexible Netflow is not supported on your hardware.

This was the reason for the BB's request to post show module

Hope to help

Giuseppe

here is the standard config working one : (tweak the configuration as per the requirement)

Configure the standard ipv4 flow record
============================================

flow record FLOW-01
match routing vrf input
match ipv4 source address
match ipv4 destination address
match ipv4 tos
match ipv4 protocol
match transport source-port
match transport destination-port
match interface input
collect transport tcp flags
collect interface output
collect counter bytes long
collect counter packets long
collect timestamp sys-uptime first
collect timestamp sys-uptime last

Configure the standard NMS
=========================================================

flow exporter NMS-1
destination x.x.x.x (IP address of NMS)
source Loopback0 - source ip address to ship flows
transport udp 2055

Configure the standard NMS
==============================================================

flow monitor ipv4-netflow-mon
description Traffic ipv4 Netflow monitor
exporter NMS02
statistics packet protocol
statistics packet size
record FLOW-01

interface vlan100 - this is layer 3 interface
ip flow monitor ipv4-netflow-mon input
ip flow monitor ipv4-netflow-mon output
end
