Cisco IOS XE Cupertino 17.9.x Release Notes for Catalyst 9200 Series Switches

Product Overview

The Cisco Catalyst 9200 Series switches are entry-level enterprise-class access switches designed for intent-based networking. They provide security, mobility, cloud, and IoT capabilities, building on the Cisco Catalyst 9000 family. Key features include MACsec encryption, field-replaceable power supplies and fans, modular uplinks, and support for Cisco IOS XE.

Hardware and Licensing

The series supports various models, including C9200 and C9200L variants, with different port configurations and PoE capabilities. Licensing is managed via Smart Licensing, with tiers including Network Essentials, Network Advantage, DNA Essentials, and DNA Advantage. Users should consult the Cisco Feature Navigator to verify specific feature support for their license level.

Software Upgrades

Upgrading the switch software is performed using the install mode. The process involves cleaning up inactive files, copying the new image to flash memory, setting the boot variable to packages.conf, and using the install add file activate commit command. It is critical not to power off the device during the upgrade process.

Important Considerations

• Unsupported Features: Certain features like Cisco TrustSec NDAC, StackWise Virtual, and specific Layer 2/MPLS protocols are not supported on this platform.
• Hidden Commands: Access to hidden commands should only be performed under the guidance of Cisco TAC.
• QoS Constraints: Ensure the total queuing buffer does not exceed 100% when configuring QoS policies.
• Stacking: C9200 and C9200L SKUs cannot be mixed in the same stack.

Troubleshooting and Support

For troubleshooting, users can utilize the Cisco Bug Search Tool to identify and track software bugs. Detailed support documentation, including hardware installation guides and MIB locators, is available on the official Cisco support website.
