Cisco provides a REST API. Using curl or Python, you can programmatically download the n9k-c9372px-e software:
~800 MB to 1.1 GB.

The portal will display a drop-down menu of available NX-OS versions. Cisco recommends specific releases for stability. For the 9372PX-E, focus on:
Software-Defined Networking (SDN) using a Cisco APIC controller. How to Download
| Problem | Likely Cause | Resolution | | :--- | :--- | :--- | | | No service contract attached to CCO ID. | Contact Cisco TAC or your reseller to link contract. | | "Invalid image for platform" error | Downloaded image for 9372PX (non-E) or 9300-EX. | Filter search by exact N9K-C9372PX-E . | | Bootflash insufficient space | Older logs or debug files. | Run delete /force /recursive volatile: and clean command. | | Feature not supported after upgrade | Moved from 7.x to 10.x without migration. | Downgrade to 9.3(11) or check release notes for deprecated CLIs. |
Do not download releases newer than 10.2(x) unless explicitly verified. The 9372PX-E uses the older Alamosa Plus ASIC, which drops support in later 10.3+ trains.
