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 3232C and 3264Q switches use an enhanced version of Cisco NX-OS software with a single binary image, which simplifies image management.

Bug ID

Description

CSCuu47831

When the no diagnostic monitor module 1 test all command is used to disable all of the diagnostic tests, the RewriteEngineLoopback test is not disabled.

Workaround: To disable the RewriteEngineLoopback test, use the no diagnostic monitor module 1 test 14 command.

Installation Notes

Only one software image is required to load the Cisco NX-OS operating system. For installation instructions, see the Cisco Nexus 9000 Series NX-OS Software Upgrade and Downgrade Guide.

Limitations

This section lists limitations related to Cisco NX-OS Release 7.0(3)IX1(2a):

■        Layer 3 routed traffic for missing Layer 2 adjacency information is not flooded back onto VLAN members of ingress units when the source MAC address of routed traffic is a non-VDC MAC address. This limitation is for hardware flood traffic and can occur when the SVI has a user-configured MAC address.

■        The neighbor-down fib-accelerate command is supported in a BGP-only environment.

■        When a routed access control list (ACL) is applied to multiple switched virtual interfaces (SVIs) in the egress direction, TCAM resources are not shared.

■        When a VLAN ACL is applied to multiple VLANs, TCAM resources are not shared.

■        The 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.

■        When multiple port VLAN mappings are configured on an interface during a rollback operation, the rollback feature fails.

Unsupported Features

This section lists the features that are supported in Cisco Nexus 9000 Series NX-OS Release 7.0(3)I1(2) but not in Cisco NX-OS Release 7.0(3)IX1(2a):

■        Automatic negotiation support for 25G and 50G ports on the Cisco Nexus 3232C switch

■        Cisco Nexus 2000 Series Fabric Extenders (FEX)

■        Cisco NX-OS to ACI conversion (The Cisco Nexus 3232C and 3264Q switches operate only in Cisco NX-OS mode.)

■        Delayed Link Aggregation Control Protocol (LACP)

■        Designated router delay

■        DHCP snooping

■        Dynamic ARP inspection (DAI)

■        Intelligent Traffic Director (ITD)

■        IP source guard (IPSG)

■        Policy-based routing (PBR)

■        Port loopback tests

■        Precision Time Protocol (PTP)

■        Private VLANs (PVLANs)

■        Q-in-Q VLAN tunnels

■        Resilient hashing

■        Switchport blocking

■        Symmetric hashing

■        TAP aggregation

■        Virtual Machine (VM) Tracker

■        Virtual port channel (vPC) peering between Cisco Nexus 3232C or 3264Q switches and Cisco Nexus 9300 Series switches or between Cisco Nexus 3232C or 3264Q switches and Cisco Nexus 3100 Series switches

■        VXLAN

Other Unsupported Features

This section lists the features that are not supported in both Cisco Nexus 9000 Series NX-OS Release 7.0(3)I1(2) and Cisco NX-OS Release 7.0(3)IX1(2a):

■        DHCP subnet broadcast is not supported.

■        Due to a Poodle vulnerability, SSLv3 is no longer supported.
