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 Nexus 9000 Series uses an enhanced version of Cisco NX-OS software with a single binary image that supports every switch in the series, which simplifies image management.
This section includes the following topics:

Cisco Nexus Release 6.1(2)I2(2a) runs on the Cisco Nexus 3164 switch (N3K-C3164Q-40GE).
The Cisco NX-OS Release 6.1(2)I2(2a) supports the software features listed in this section.
– show nve vni vni_number counters
– show nve peers peer_IP_address interface interface_ID counters
– clear nve vni vni_number counters
– clear nve peers peer_IP_address interface interface_ID counters
– The show queuing module 1 command displays queuing information for all interfaces on module 1.
– The show queuing command displays information for all interfaces in the system. The output of this command can be quite large.
For additional information, see the Cisco Nexus 9000 Series NX-OS Quality of Service Configuration Guide.
When you configure QoS features, and the system requests MQC objects, you can use system-defined objects for 4q mode or system-defined objects for 8q mode.
The following switches support system-defined objects for 8q mode:
Changing to 8q mode from the default 4q mode allows you to direct network traffic to queues 4 through 7, which provides 4 additional queues over the currently available 4 queues.
For additional information, see the Cisco Nexus 9000 Series NX-OS Quality of Service Configuration Guide.
Fabric modules with the network forwarding engine (NFE) can operate in two modes: full-rate mode (FRM) or oversubscribed mode (OSM). In OSM, all 32 ports are enabled on the NFE for a total I/O bandwidth of 1280G. In FRM, only 24 ports are enabled on the NFE for a total bandwidth of 960G at all packet sizes. In OSM, the NFE cannot run at line rate for packet sizes of less than 200 bytes.
Starting in Cisco NX-OS Release 6.1(2)I2(2a), fabric module NFEs can run in FRM or OSM, but OSM is the default mode. The new system fabric-mode full-rate command allows you to configure the system fabric in FRM or OSM mode.
For additional information, see the Cisco Nexus 9000 Series NX-OS High Availability and Redundancy Guide.
Cisco NX-OS Release 6.1(2)I2(2a) adds support for traffic storm control counters, including the ability to generate an SNMP trap and a syslog message when the traffic storm control limit is reached.
For information on how to configure traffic storm control counters, see the Cisco Nexus 9000 Series NX-OS Security Configuration Guide.
Cisco NX-OS Release 6.1(2)I2(2a) adds the ability to advertise newly learned Border Gateway Protocol (BGP) routes only after these routes are confirmed by the Forwarding Information Base (FIB) and programmed in the hardware.
For more information, see the Cisco Nexus 9000 Series NX-OS Unicast Configuration Guide.
Only one software image (called nx-os) is required to load the Cisco NX-OS operating system. This image runs on all Cisco Nexus 9000 Series switches. For installation instructions, see the Cisco Nexus 9000 Series NX-OS Software Upgrade and Downgrade Guide.
To perform a software upgrade, follow the installation instructions in the Cisco Nexus 9000 Series NX-OS Software Upgrade and Downgrade Guide.
For information about software maintenance upgrades, see the “Performing Software Maintenance Upgrades” section in the Cisco Nexus 9000 Series NX-OS System Management Configuration Guide.
Note If you perform a software maintenance upgrade (SMU) and later upgrade your device to a new Cisco NX-OS software release, the new image will overwrite both the previous Cisco NX-OS release and the SMU package file.
This section lists limitations related to Cisco NX-OS Release 6.1(2)I2(2a).
– Cisco Nexus 9500 Series 36-port 40-Gigabit QSFP I/O module (N9K-X636PQ)
