compact models. However, legacy 3560 switches with only 16 MB of flash memory cannot support this version; they require at least 32 MB of flash and 128 MB of DRAM. The Upgrade Process
This image is available free from Cisco without a service contract. You need a valid CCO login with contract coverage for Catalyst 3560. As a late-stage maintenance release, 15
Ensure your switch has enough Flash memory (typically 16MB or 32MB depending on the model) and RAM to support IOS 15.x.
The Cisco Catalyst 3560 is End-of-Life (EoL). While this firmware provides the best possible stability for existing units, consider migrating to Catalyst 9200 or 9300 series for modern security features and official support.
