| 04-Software Patching Examples | 55.86 KB |
Introduction
This document provides software patching examples that use ISSU install commands.
Prerequisites
The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.
This document assumes that you have basic knowledge of ISSU that uses install commands.
Example: Patching software
Network configuration
As shown in Figure 1, the switch and the TFTP server can reach each other. The switch is running CMW910-SYSTEM-R1116, and it is not been patched before.
Use the patch image file CMW910-SYSTEM-R1116H04.bin to fix bugs without rebooting the switch.
