Cisco NX-OS software is a data center-class operating system designed for performance, resiliency, scalability, manageability, and programmability at its foundation. The Cisco NX-OS software provides a robust and comprehensive feature set that meets the requirements of virtualization and automation in mission-critical data center environments. The modular design of the Cisco NX-OS operating system makes zero-impact operations a reality and enables exceptional operational flexibility.
The Cisco NX-OS 7.0(3)F1(1) image is specifically designed to support and bring up the N9K-X9636C-R and N9K-X9636Q-R line cards and the N9K-C9508-FM-R fabric modules of the Cisco Nexus 9508 switch.
This section includes the following sections:
Table 2 lists the Cisco Nexus 9508 switch hardware that Cisco NX-OS Release 7.0(3)F1(1) supports. For additional information about the supported hardware, see the Cisco Nexus 9508 NX-OS Mode Switch Hardware Installation Guide.

The following software features are supported in Cisco NX-OS Release 7.0(3)F1(1), but are not supported in Cisco NX-OS Release 7.0(3)I2(4):
The following features are supported only for the N9K-X9636C-R and N9K-X9636Q-R line cards and the N9K-C9508-FM-R fabric modules in a Cisco Nexus 9508 switch running Cisco NX-OS Release 7.0(3)F1(1) or later:
■ Ingress Queuing—This feature, which is used to configure ingress buffer thresholds, is supported on the N9K-X9636C-R and N9K-X9636Q-R line cards and the N9K-C9508-FM-R fabric modules. For more information, see the Cisco Nexus 9000 Series NX-OS Quality of Service Configuration Guide
■ Multicast Queuing—This feature, which is enabled automatically for the N9K-X9636C-R and N9K-X9636Q-R line cards and the N9K-C9508-FM-R fabric modules, prioritizes multiple streams of multicast traffic in order to achieve better throughput.

This section lists limitations related to Cisco NX-OS Release 7.0(3)F1(1).
■ For the Cisco NX-OS 7.0(3)F1(1) release, the VXLAN network identifier (VNID) 16777215 is reserved and should not be configured explicitly.
■ CoPP (Control Plane Policing) cannot be disabled. If you attempt to disable it, an error message appears.
■ The skip CoPP policy option has been removed from the Cisco NX-OS initial setup utility because using it can impact the control plane of the network.
