Do you require any further support?

This document explains the step-by-step procedure to upgrade the software image on Catalyst 4500/4000 series switches that run CatOS on Supervisor I and II modules, Cisco IOS® on 4232-L3 module, and Cisco IOS on Supervisor III, IV, and V modules. The software image upgrade is necessary for these reasons: Implement new features in your network which are available in new software releases. Install a new line card that is not supported by the current software version you run on the switch. Fix a known bug that affects your switch if the bug is resolved in the future software release. https://www.cisco.com/c/en/us/support/docs/switches/catalyst-4000-series-switches/27848-179.html.
