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(2) image is specifically designed to support and bring up the N36180YC-R of the Cisco Nexus 3600 Series switches.
This section includes the following sections:
■ Supported Device Hardware
■ Supported Optics
Table 2 lists the Cisco Nexus 3600 switch hardware that Cisco NX-OS Release 7.0(3)F3(2) supports. For additional information about the supported hardware, see the Cisco Nexus 3600 NX-OS Mode Switch Hardware Installation Guide.
Table 2. Cisco Nexus 3600 Switch Hardware
The Cisco Nexus 36180YC-R (N3K-C36180YC-R) is a 1 rack unit (RU) switch with 48 10/25-Gigabit SFP28 ports and 6 100-Gigabit QSFP28, 1 management ports, 1 console port, and 1 USB port. The switch supports both port-side exhaust and port-side intake airflow schemes. The switch requires one AC or DC power supply for operations, but it can have a second power supply for redundancy.
To determine which transceivers and cables are supported by this switch, see the Transceiver Module (TMG) Compatibility Matrix.

This section lists limitations related to Cisco NX-OS Release 7.0(3)F3(2).
■ 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.
