Usage Guidelines and Limitations
This section lists the usage guidelines and limitations for Cisco NIR:
■ 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. See Hardware Requirements.
■ Telemetry for hardware TCAM utilization, such as forwarding TCAM and ACL TCAM are not supported on Cisco Nexus C9504, C9508, and C9516 Series platforms.
■ Upgrade from Cisco NIR 2.0.x to Cisco NIR 2.1.1 App on Cisco DCNM 11.3(1) is not supported.
