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(5) image is specifically designed to support and bring up the N3K-C3636C-R and N3K-C36180YC-R switches of the Cisco Nexus 3600 platform switches.

Hardware

N3K-C3636C-R

The Cisco Nexus 3636C-R (N3K-C3636C-R) is a 1 rack unit (RU) switch with 36 100-Gigabit QSFP28 ports. 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 has two power supplies, one for operations and the other for redundancy. Both power supplies must be either AC power supplies or DC power supplies.

N3K-C36180YC-R

The Cisco Nexus 36180YC-R (N3K-C36180YC-R) is a 1 rack unit (RU) switch with 48 1/10/25-Gigabit SFP ports and 6 40-Gigabit QSFP/100-Gigabit QSFP28 ports, 1 management port, 1 console port, and 1 USB port. The switch supports both port-side exhaust and port-side intake airflow schemes. The switch has two power supplies, one for operations and the other for redundancy. Both power supplies must be either AC power supplies or DC power supplies.

Supported Optics

See the Cisco Transceiver Modules Compatibility Information for a list of supported optical components.

Limitations

This section lists limitations related to Cisco NX-OS Release 7.0(3)F3(5).

■        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.
