Issue/Introduction

Unable to collect physical netflows from Cisco 9000 series switches using Aria Operations for Networks

Environment

Aria Operations for networks 6.x

Resolution

You will need to configure a collector specifically for collectAing flows:   Add a Physical Flow Collector for NetFlow and sFlow

After that, you will need to configure the netflow profile on the 9k and point it at the new flow collector:  Configuring a Netflow Collector for Cisco Nexus 9000 Series Switches

Example default configuration:

feature netflow
!
    flow record vrni-record
    match ipv4 source address
    match ipv4 destination address
    match transport source-port
    match transport destination-port
    collect transport tcp flags
    collect counter bytes
    collect counter packets
    collect timestamp sys-uptime first
    collect timestamp sys-uptime last

You need to add the following lines:

match ipv4 protocol
match interface input
