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)F3(3c) image is specifically designed to support and bring up the N3K-36180YC-R switch of the Cisco Nexus 3600 Series platform switches.

Limitations

This section lists limitations related to Cisco NX-OS Release 7.0(3)F3(3c).

■        The PTP process restart and system switchover accumulates high corrections for a few seconds. For more information, see CSCvg49023.

■        The LDP neighbor might flap on switchover in a scaled setup with many interfaces. Increase the discovery hello hold time for MPLS under the MPLS LDP configuration. For more information, see CSCvg71349.

■        CoPP (Control Plane Policing) cannot be disabled. If you attempt to disable it, an error message appears. For more information, see CSCvi09329.

■        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. For more information, see CSCvc44819.

■        IPv4 traffic might drop when only IPv6 uRPF is enabled on the interface. For more information, see CSCvh99632.
