The Cisco NIR application requires that physical servers hosting Cisco DCNM computes as VMs are atleast Cisco C220-M4 category. It is also required that a compute be hosted on a data store with a dedicated hard disk of atleast 500GB.

The following are hardware requirements for Cisco NIR app on Cisco DCNM.

  1. Flow Telemetry is supported on the following series switches and line cards:

    Cisco Nexus 9300-EX, -FX, and -FX2 platform switches.

  2. Software Telemetry is not supported on the following series switches:

    • Cisco N9K -GX and -FX3 platform switches.

    • Cisco N3K-C3408-S, N3K-C3432D-S, N3K-C34200YC-SM, N3K-34180YC, and N3K-3464C switches.
