ACI and Netflow

[eugenia]

Can an ACI fabric export netflow data and if so are there any configuration guides/examples?

[Vladimir Stepanov]

seems like not. They suggest to send traffic sampling using ERSPAN and then convert it into netflow.

Vladimir, Thank you for responding and confirming.  I was not sure that was still the case!

Hello!

Thanks for using support forums!

Netflow support will be coming out in December/January timeframe. Look forward to some configuration documents then!

It's Feb now...is NetFlow exports supported? If so, can you send link to docs?

Thanks

H Scherrav,

What is the difference in between configuring a Fabric Netflow policy and Tenant Netflow policy? Is this supposed to configure both? or either one will suffice? And I am a bit confused on what is the purpose of EPG Type, Associated EPG and Associated VRF?

Why do I have to set a /20 network for the source? Is there any other way to set a single /32 address? 

apic1(config-tn-flow-exporter)# source address
inband-mgmt-ip oob-mgmt-ip ptep
apic1(config-tn-flow-exporter)# source address 1.1.1.1 ?
<CR>
apic1(config-tn-flow-exporter)# source address 1.1.1.1
Error: Source address can have a mask upto 20 and 116 for ipv4 and ipv6 addresses respectively
Command execution failed.
apic1(config-tn-flow-exporter)# source address 1.1.0.0/20
apic1(config-tn-flow-exporter)# no source address
