    Hi all,
     
    I'm having difficulty configuring NetFlow on Aruba CX 6000, 6400, and 8300 Series switches. I've applied the following configuration, but I'm not seeing any traffic data appear in SolarWinds:
    flow exporter SolarWinds
        destination 10.20.20.100 vrf default
     
    flow record flowRecord
        match ipv4 destination address
        match ipv4 protocol
        match ipv4 source address
        match ipv4 version
        match transport source port
        collect application name
        collect counter bytes
        collect counter packets
        collect timestamp absolute first
        collect timestamp absolute last
     
    flow monitor flowMonitor
        exporter SolarWinds
        record flowRecord
     
    interface 1/1/51
        description Switch-Uplink-To-Core
        ip flow monitor flowMonitor in



    Is there anything missing in my configuration?
    Any guidance, corrections, or documentation references for configuring NetFlow (sFlow/IPFIX) on Aruba CX switches would be greatly appreciated.

    Thanks in advance.

    Aruba supports sFlow. Try 

    sflow enable
    sflow collector SolarWinds 10.20.20.100 port 6343
    sflow agent-ip 10.20.20.1
     
    interface 1/1/51
        sflow enable
    or globally on all interfaces:
    sflow enable
    sflow collector SolarWinds 10.20.20.100 port 6343
    sflow agent-ip 10.20.20.1
    sflow sampling-rate 4096
    if you need sampling:
    sflow sampling-rate 2048
    Also, make sure SolarWinds NTA is configured to receive UDP/6343, not NetFlow (UDP/2055/9996/4739).
