This update replaces the previous IOS version on Catalyst 3560-E switches with . As a Universalk9 image, it supports both LAN Base and IP Services feature sets, activated via license level.
The is a critical software update for the Cisco Catalyst 3560-E and 3560-X series switches, operating on the robust Cisco IOS 15.2(4)E platform. As a "-UPD-" (Updated) repack, this firmware ensures that enterprise-level networking hardware remains secure, stable, and compliant with modern network demands.

As network environments evolve to meet higher security standards and support modern PoE+ devices, keeping legacy hardware updated is essential. The Cisco Catalyst 3560-E and 3560-X series switches, while mature, remain workhorses in many campus networks. For administrators looking to secure these devices, the c3560e-universalk9-mz.152-4.E10.bin (often referred to as 15.2(4)E10) is a critical update release from the Cisco IOS 15.2E series .
While this firmware extends the life of the 3560E, Cisco strongly recommends migrating to the Catalyst 9200 or 9300 series. However, for legacy networks that cannot be replaced yet, c3560e-universalk9-mz.152-4.e10.bin -UPD- is the gold standard.
Includes fixes for multiple security advisories and potential CVEs.
