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 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.
System Requirements
This section includes the following topics:
Supported Device Hardware
Table 2 lists the Cisco Nexus 9000 Series hardware that Cisco NX-OS Release 6.1(2)I1(1) supports.
Cisco Nexus 9500 36-port, 40 Gigabit Ethernet QSPF aggregation module |

For additional information about the supported hardware, see the Cisco Nexus 9508 Switch Site Preparation and Hardware Installation Guide.
Supported Optics
Table 3 lists the optical components that Cisco NX-OS Release 6.1(2)I1(1) software supports. For updated support information, also see the Compatibility Matrix.
Note
For the current release, if you are using the 4 10G breakout cables with a Cisco Nexus 9000 Series switch, all ports on the I/O module must be set to breakout mode.

Installation Notes
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.
Limitations
Cisco NX-OS Release 6.1(2)I1(1) does not support the following features:
- The Generic Online Diagnostics (GOLD) port loopback test
- An ERSPAN type destination
- An egress filter on an ACL-based SPAN
- All VLAN features of SPAN/ERSPAN
- FEX
- Cisco NX-OS Release 6.1(2)I2(2b) supports flooding for Microsoft Network Load Balancing (NLB) unicast mode on Cisco Nexus 9500 Series switches but not on Cisco Nexus 9300 Series switches. NLB is not supported in max-host system routing mode. NLB multicast mode is not supported on Cisco Nexus 9500 or 9300 Series switches.
Note To workaround the situation of Unicast NLB limitation, we can statically hard code the ARP and MAC address pointing to the correct interface. Please refer to bug ID CSCuq03168 in detail in the “Open Caveats—Cisco NX-OS Release 6.1” section.
– Fiber Channel over Ethernet (FCoE)
- When routed ACL is applied to multiple SVIs (switched virtual interfaces) in the egress direction, TCAM resources are not shared.
- When VACL (VLAN ACL) is applied to multiple VLANs, TCAM resources are not shared.
- N9K hardware does not support range checks (layer 4 operators) in egress TCAM. Because of this, ACL/QoS policies with layer 4 operations-based classification need to be expanded to multiple entries in the egress TCAM. Egress TCAM space planning should take this limitation into account.
- If the same QOS policy and ACL is applied on multiple interfaces, the label will be shared only when the qos-policy is applied with the no-stats option.
- Limitations for ALE uplink ports are listed at the following URL:
