Catalyst 9300 Upgrade
The Catalyst 9300 is the direct successor to both the 3850 and 3750-X — identical StackWise-480 stacking, same IOS CLI heritage, plus programmable ASIC and DNA Center.
About the Cisco Catalyst 3850 / 3750-X
The Cisco Catalyst 3850 and Catalyst 3750-X were the gold standard enterprise access switches of their generation — widely deployed as the primary wired access platform in enterprise campuses throughout the 2010s. The 3850 introduced StackWise-480 (480 Gbps stack bandwidth), unified wired+wireless management, and a fully programmable ASIC in the Catalyst line. The 3750-X brought StackWise-160 and IP Services routing to mid-range enterprise deployments.
Cisco has announced end-of-sale for both the Catalyst 3850 and 3750-X Series. The Cisco Catalyst 9300 is the direct successor — retaining the same StackWise-480 stacking architecture that 3850 operators are familiar with, while adding Cisco Uadp 2.0 programmable ASIC, Cisco IOS-XE, DNA Center SD-Access integration, MACsec hardware encryption on all ports, and streaming telemetry not available on the 3850 platform.
