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(1) image is specifically designed to support Cisco Nexus 3600 platform 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(1) 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 10/25-Gigabit SFP28 ports and 6 100-Gigabit QSFP28, 2 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.
See the Cisco Transceiver Modules Compatibility Information for a list of supported optical components.

Table 3 lists the open caveats in Cisco NX-OS Release 7.0(3)F3(1). Click the bug ID to access the Bug Search tool and see additional information about the bug.
Table 3 Open Caveats in Cisco NX-OS Release 7.0(3)F3(1)
The vPC port channel interfaces remain down after exiting the maintenance mode.
A drop in the throughput is seen during steady traffic of 600G or more.
After a LC reload in vPC multicast, traffic takes long time to converge.
After enabling ACL (RACL) log, 60% frame loss is encountered.
The QoS service policy cannot be applied if it includes ACL that contains a match dhscp.
After the no vlan range on a vPC, the MAC is not deleted.
Multiple vpc POs in BA_Inconsistent state in vpc secondary after reload.
This section lists limitations related to Cisco NX-OS Release 7.0(3)F3(1).
■ 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.
■ IPv4 traffic might drop when only IPv6 uRPF is enabled on the interface.
■ The sum of queue limits in a policy is not checked and therefore can exceed 100%. Make sure to check the limits while creating the queuing policy.
