sflow on nexus 9000 not working

janroc over 6 years ago

Hi all,

We have cisco nexus 9000 with NXOS: version 7.0(3)I4(7) and enable sflow.

I see packet is coming to the NTA server with wireshark, but not showing up in NTA web interface.

Any suggestions of wrong configuration?

version 7.0(3)I4(7)
feature sflow

sflow sampling-rate 50000
sflow max-sampled-size 200
sflow counter-poll-interval 100
sflow max-datagram-size 2000
sflow collector-ip x.x.x.x vrf DC-Production
sflow collector-port 2055
sflow agent-ip s.s.s.s

sflow data-source interface port-channel10
sflow data-source interface port-channel101
sflow data-source interface port-channel103
sflow data-source interface port-channel105

Hi Jan,
Your setting is ok.
Take a look under NetFlow Traffic Analyzer Settings > NetFlow Collector Services > "Configure name and collection ports for each NetFlow collector."
Are you sure that NTA is using the port 2055 ?
Did you add your switch under Manage Nodes ? Then, can you see your interfaces clicking on "list resources" ?

sflow counter-poll-interval 100
sflow max-datagram-size 2000

sflow collector-port 2055
sflow agent-ip 2.2.2.2
sflow data-source interface EthernetX
