Introduction

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.

New Software Features in Cisco NX-OS Release 7.0(3)F1(1)

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. For more information, see the Cisco Nexus 9000 Series NX-OS Multicast Routing Configuration Guide.

Limitations

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.
