Introduction

This document provides software patching examples that use 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.

Example: Patching software

Network configuration

As shown in Figure 1, the two-chassis IRF fabric and the TFTP server can reach each other. The IRF members are running CMW710-SYSTEM-R6312, and they have not been patched before.

Use the patch image file CMW710-SYSTEM-R6312H04.bin to fix bugs without rebooting the members.

Restrictions and guidelines

When you patch software for a centralized IRF device, follow these restrictions and guidelines:

·     The first time you install patch images, you must start with the master. For subsequent patch installations, you must start with the subordinate members.

·     The patch image version must match the device model and Comware version. For example, to fix bugs in CMW710-SYSTEM-R6312.bin, you must use CMW710-SYSTEM-R6312H04.bin.

Procedures

# Download the patch image file CMW710-SYSTEM-R6312H04.bin from the TFTP server to the root directory of the flash memory on the master.

<Sysname> tftp 2.2.2.2 get CMW710-SYSTEM-R6312H04.bin

Press CTRL+C to abort.

# Activate the patch images on the master first and then on the subordinate member. This sequence is used because no patch images have been activated on the IRF fabric.

<Sysname> install activate patch flash:/CMW710-SYSTEM-R6312H04.bin slot 1

This operation maybe take several minutes, please wait.............Done.

<Sysname> install activate patch flash:/CMW710-SYSTEM-R6312H04.bin slot 2

This operation maybe take several minutes, please wait.............Done.

The patch images take effect immediately after they are activated.

# For the patch images to take effect after a reboot, commit the software changes.

<Sysname> install commit

Verifying the configuration

# Verify that the patch images have been activated successfully.

<Sysname> display install active
