I have been struggling with setting up Netflow config for Cisco C9300 Catalyst switches to work with Solarwinds NTA. I am also aware of someone posting their configs here but so far none of them are working for me. I think the problem is we like to pull Netflow data on L2 Port-Channel interfaces and VLAN interfaces. The config script I use for ASR1001 routers is fine with NTA but I think it is a bit different for Cisco C9300 Catalyst switches. Could anyone please point me to the right direct what needs to be done. Here is the config snip I use for ASR1001.
flow record Recorder
match ipv4 tos
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
match flow direction
collect counter bytes long
collect counter packets long
collect interface input
collect transport tcp flags
collect timestamp absolute first
collect timestamp absolute last
flow exporter Exporter
description Export to NTA
transport udp 2055
flow monitor Monitor
ip flow monitor Monitor input
Flexible netflow is not supported on layer 2 port-channel interfaces. However you can setup flexible netflow on the individual layer2 ports that are in the port-channel.
I would suggest open a ticket for support. They can verify this netflow configuration and use a wireshark on the orion application server.
And when you navigate to the specific device it says "no data available"?
Is the device reaching the orion application server?
You can use wireshark to verify if its reaching the server.
