New and Changed Information
New Hardware Support
- Support added for the N9K-C93120TX leaf switch with 96×1/10G and 6×40G interfaces.
- Support for the N9K-M6PQ-E 6‑port 40G GEM module.
- Support for new power supplies: N9K-PUV-1200W and UCS-PSU-6332-DC.
Software Features
For detailed software features, see the APIC 1.2(1k) controller release notes associated with this ACI software.
Installation Guidance
To install or replace a pluggable module:
- Clear the switch’s current configuration.
- Power off the switch.
- Install or replace the hardware module.
- Power the switch back on.
Refer to the ACI fabric hardware installation guide for complete procedures.
Compatibility Notes
- Only use optics and modules that are supported for the specific device models.
- Unsupported third‑party optics may behave unpredictably.
- Link‑level flow control is not supported on ACI‑mode switches.
- Fabric uplink ports should not be used as fabric extender ports.
- A 10G interface is required on leaf nodes for controller connectivity.
Usage Guidelines
- Ensure required control and management protocols are permitted through fabric contracts.
- Avoid direct physical connections between switches from different ACI fabrics.
- Verify MACsec and CloudSec compatibility if used.
- Follow supported optics and breakout configuration rules to avoid hardware issues.
Known Behaviors and Issues
This release includes behaviors and caveats that may affect operations:
- Fabric extender diagnostic information may not always be visible.
- Some interface and control commands can behave differently due to the underlying shell.
- Certain multicast and packet handling behaviors may be observed under specific conditions.
- Routing and endpoint learning events may not always reflect expected output in some cases.
Refer to the official release documentation for complete details if needed.
