Known Behaviors—Cisco NX-OS Release 9.2(3)
Obtaining Documentation and Submitting a Service Request
The Cisco Nexus 3000 Series switches, which includes Cisco Nexus 3100, 3200, 3400-S, 3500, and 3600 platform switches, and Cisco Nexus 9300 and 9500 platform switches run on the same binary image, also called the “unified” image.
Cisco NX-OS Release 9.2(1) is the first release that adopts unified version numbering. As more platforms have been added, there is no need to have a “platform” designator as used in the past.
An example of a previous release number is: 7.0(3)I7(4). In this format, the ‘I’ is the platform designator.
Moving forward for the previously identified platforms, we will be adopting the simplified 3-letter versioning scheme. For example, a release with X.Y(Z) would mean:
X – Unified release major
Y – Major / Minor release
Z – Maintenance release (MR)
Where the Z = 1 is always the first FCS release of a Major/Minor release.
Note: In order to accommodate upgrade compatibility from an older software version that is expecting a platform designator, when the install all command is entered or the show install all impact command is entered, the version string appears as 9.2(1)I9(1). The “I9(1)” portion of the string can be safely ignored. It will later appear as 9.2(1).
Temporary licenses with an expiry date are available for evaluation and lab use purposes. They are strictly not allowed to be used in production. Please use a permanent or subscription license that has been purchased through Cisco for production purposes.
When you downgrade from Cisco NX-OS Release 9.2(3) to an earlier release, the features that use the ACI+NX-OS Essentials, Advantage, and add-on licenses or the Hardware Streaming Telemetry license continue to work in honor mode in the downgraded version. In addition, the output of the how license usage command continues to include entries for these unsupported licenses.
For more information, see the Cisco NX-OS Licensing Guide.

Cisco Nexus 9000 Series, Cisco Nexus 9500-R/Cisco Nexus-3600-R Series, Cisco Nexus 3000 Series, and Cisco Nexus 3500 Series are platforms that run on the unified software and binary. Since some caveats listed against these platforms could be applicable to the Cisco Nexus 3000 series platform too, we recommend that you review the list of caveats in the Release Notes of the other platforms for this release, to see if those are applicable to your network configuration.
This section includes the following topics:
■ Resolved Caveats—Cisco NX-OS Release 9.2(3)
■ Open Caveats—Cisco NX-OS Release 9.2(3)
■ Known Behaviors—Cisco NX-OS Release 9.2(3)

Table 2 Known Behaviors in Cisco NX-OS Release 9.2(3)
Bug ID |
Description |
On Cisco Nexus 9300-EX, 9348GC-FXP, 93108TC-FX, 93180YC-FX, 9336C-FX2, and 93240YC-FX2 switches, when 802.1q EtherType has changed on an interface, the EtherType of all interfaces on the same slice will be changed to the configured value. This change is not persistent after a reload of the switch and will revert to the EtherType value of the last port on the slice. |
■ Release 9.2(3) brings in a new kernel and new processes.
■ Interface counter statistics are grouped together in the XML/JSON output. The output for the show interface-counters command in JSON format has changed/
■ NX-API does not support insecure HTTP by default.
■ NX-API does not support weak TLSv1 protocol by default.
■ Stronger ciphers are used in this release.
■ A new command, no service password-recovery is supported.
■ Only one version out of v4 and v6 versions of the uRPF command can be configured on an interface. If one version is configured, all the mode changes must be done by the same version. The other version is blocked on that interface. Cisco Nexus 9300-EX, 9300-FX, and 9300-FX2 platform switches do not have this limitation and you can configure v4 and v6 version of urpf cmd individually.
■ In the NX-API sandbox, whenever XML or JSON output is generated for the show run command or the show startup command, the output contains additional characters.
</nf:source> <============nf: is extra
<namespace> : extra characters are seen with XML and JSON from NX-API.
To perform a software upgrade, follow the installation instructions in the Cisco Nexus 9000 Series NX-OS Software Upgrade and Downgrade Guide, Release 9.2(x).
o 9.2(1)
o 7.0(3)I7(4), 7.0(3)I7(5), 7.0(3)I7(5a), 7.0(3)I7(6), 7.0(3)I7(7)
Note: Enhanced ISSU to Cisco NX-OS Release 9.2(3) is not supported as there are kernel fixes that cannot take effect without reloading the underlying kernel.
■ When downgrading from the Cisco NX-OS Release 9.2(3) to earlier releases, make sure that the ACL TCAM usage for ingress features does exceed the allocated TCAM space in the absence of the label sharing feature. Label sharing is a new feature in Cisco NX-OS Release 9.2(3). Otherwise, interfaces with RACLs that could not fit in the TCAM will be disabled after the downgrade.
■ When upgrading from Cisco NX-OS Release 9.2(2) or earlier releases to Cisco NX-OS Release 9.2(3), you need to make sure that ingress RACL TCAM region is not more than 50% full. Otherwise, the atomic update feature will be enabled after the upgrade and interfaces with RACLs that exceed 50% of TCAM allocation will remain down.
■ When upgrading from Cisco NX-OS Releases 7.0(3)I4(8), 7.0(3)I5(3), and 7.0(3)I6(1) to Cisco NX-OS Release 9.2(3) results in a disruptive upgrade. If syncing images to standby SUP failed during the disruptive upgrade from Cisco NX-OS Releases 7.0(3)I4(8), 7.0(3)I5(3,) or 7.0(3)I6(1) to 9.2(3), you should manually copy the image to the standby SUP and perform the disruptive upgrade.
■ When upgrading to Cisco NX-OS Release to 9.2(3) from any release prior to 7.0(3)I2(3) an intermediate upgrade to 7.0(3)I4(x), 7.0(3)I5(x), 7.0(3)I6(x), or 7.0(3)I7(x) is required. We recommend using Cisco NX-OS Release 7.0(3)I4(8) or 7.0(3)I7(4) as the interim release to aid in a smooth migration. For further details, please refer to CSCvk66763.
■ When upgrading from Cisco NX-OS Release 7.0(3)I6(1) or 7.0(3)I7(1) to Cisco NX-OS Release 9.2(3), if the Cisco Nexus 9000 Series switches are running vPC and they are connected to an IOS-based switch via Layer 2 vPC, there is a likelihood that the Layer 2 port channel on the IOS side will become error disabled. The workaround is to disable the spanning-tree etherchannel guard misconfig command on the IOS switch before starting the upgrade process. Once both the Cisco Nexus 9000 Series switches are upgraded, you can re-enable the command. For more information, see defect CSCvg05807.
■ An upgrade performed via the install all command for Cisco NX-OS Release 7.0(3)I2(2b) to Release 9.2(3) might result in the VLANs being unable to be added to the existing FEX HIF trunk ports. To recover from this, the following steps should be performed after all FEXs have come online and the HIFs are operationally up:
1. Enter the copy run bootflash:fex_config_restore.cfg command at the prompt.
2. Enter the copy bootflash:fex_config_restore.cfg running-config echo-commands command at the prompt.
■ In Cisco NX-OS Release 7.0(3)I6(1) and earlier, performing an ASCII replay or running the copy file run command on a FEX HIF configuration requires manually reapplying the FEX configuration after the FEX comes back up.
■ When upgrading to Cisco NX-OS Release 9.2(3) from 7.0(3)I2(x) or before and running EVPN VXLAN configuration, an intermediate upgrade to 7.0(3)I4(x) or 7.0(3)I5(x) or 7.0(3)I6(x) is required. For further details, please refer to CSCvh02777.
■ An ISSU can be performed only from a Cisco NX-OS Release 7.0(3)I4(1) to a later image.
■ While performing an ISSU, VRRP and VRRPv3 displays the following messages:
For additional information, see the Cisco NX-OS ISSU Support application.
The following are the upgrade paths from previous 7.0(3)F3(x) releases:
■ Release 7.0(3)F3(x) -> Release 7.0(3)F3(4) -> Release 9.2(3)
NOTE: This upgrade is disruptive.
