Cisco 4351 EOL replacement options
The Cisco Catalyst C8300
Cisco recommends replacing the 4351 with the Catalyst C8300, but this platform does not go far enough to improve upon the limitations of the EOL model. For instance, both the ISR 4351 and the Catalyst C8300 replacement models are 2RU devices, making them too large for some branch and edge deployment use cases where space is limited. Additionally, while both platforms integrate with some of Cisco’s third-party partners (like ThousandEyes), Cisco is a closed ecosystem that may not support all the management, automation, and security tools needed to support an enterprise branch. Additionally, Cisco’s DNA software may not be able to control mixed-vendor infrastructure, leaving critical coverage gaps.
