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.
Example: Patching software in standalone mode
Network configuration
As shown in Figure 1, the device and the TFTP server can reach each other. The device has one active MPU (slot 0) and one standby MPU (slot 1). The MPUs are running boot image BOOT-R7536P05 and system image SYSTEM-R7536P05.
Use patch image file SYSTEM-R7536P05H01.bin to fix bugs without rebooting the device.
Software versions used
This configuration example was created and verified on S7500E-CMW710-R7536P05.
Restrictions and guidelines
When you patch software, follow these restrictions and guidelines:
· The first time you install patch images, you must start with the active MPU. For subsequent patch installations, you must start with the standby MPU.
· The patch image version must match the device model and Comware version. For example, to fix bugs in R7536P05, you must use SYSTEM-R7536P05H01.bin.
Procedures
# Download patch image file SYSTEM-R7536P05H01.bin from the TFTP server to the root directory of the CF card on the active MPU.
<Sysname> tftp 2.2.2.2 get SYSTEM-R7536P05H01.bin
Press CTRL+C to abort.

<Sysname> install commit
Verifying the configuration
# Verify that the patch images have been activated successfully.

Configuration files
The system does not save the commands used in the configuration procedures to a configuration file.
Example: Patching software in IRF mode
Network configuration
As shown in Figure 2, the two-chassis IRF fabric and the TFTP server can reach each other. Each member of the IRF fabric has one active MPU (slot 0) and one standby MPU (slot 1). The IRF members are running boot image BOOT-R7536P05 and system image SYSTEM-R7536P05.
Use patch image file SYSTEM-R7536P05H01.bin to fix bugs without rebooting the members.
Software versions used
This configuration example was created and verified on S7500E-CMW710-R7536P05.
Restrictions and guidelines
When you patch software for a centralized IRF device, follow these restrictions and guidelines:
· To install an image, you must begin with the master. On each member device, you must begin with the active MPU. To upgrade an image, you must begin with a subordinate device. On each member device, you must begin with the standby MPU.
· The patch image version must match the device model and Comware version. For example, to fix bugs in R7536P05, you must use SYSTEM-R7536P05H01.bin.
Procedures
# Download patch image file SYSTEM-R7536P05H01.bin from the TFTP server to the root directory of the CF card on the global active MPU.
<Sysname> tftp 2.2.2.2 get SYSTEM-R7536P05H01.bin
Press CTRL+C to abort.
