In my research on Application Health within Assurance, it relies on netflow data to populate this information. Currently in telemetry, we have Optimal Visibility on all switches, which doesn't include netflow.
When I try to apply Maximum Visibility which does include netflow, I get an error saying:
Netflow Profile only allowed on Routers and having version 16.x and higher
Our installation includes 2x 3850-24XS Boarder/CP nodes, a mixture of 9300 and 3650 models for edge, and Firepower 2110 firewalls.
Given the above error, will we be able to use Application Health in our environment, or would it require the purchase of an ISR/ASR?
Currently Application Health information is based on Netflow from Routers. Cisco DNA Center does not support netflow as part of switch telemetry information. So the suggestion will be to deploy an ISR/ASR and configure maximal visibility on them for optimal application health.
Hi , Request you to please upgrade the version of all the devices and also make sure IOS version is upto date on the devices netflow can be supported on version 16.x or higher which you see in error. I would not ask you to purchase a particular version of router which is not imp. with dnac. But do the above and for netflow add on feature you can purchase stealthwatch license which comes with DNA premier licensing free. With that complete netflow feature can be enabled, Just FYI. This is a bug which we can see in this link : https://quickview.cloudapps.cisco.com/quickview/bug/CSCvk54861
Right now application health requires either ISR or ASR with appropriate license levels. Application health cannot be accomplished on any switching platforms regardless of hardware or software versions. That *may* be possible in future, but not today.
