Configuration restrictions and guidelines
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 for a standalone device
Network requirements
As shown in Figure 1, the device and the TFTP server can reach each other. The device has one active MPU in slot 0 and one standby MPU in slot 1. The MPUs are running S12500-CMW710-SYSTEM-R7328P02, and they have not been patched before.
Use the patch image file S12500-CMW710-SYSTEM-R7328P02H01.bin to fix bugs without rebooting the device.
Software version used
This configuration example was created and verified on S12500-CMW710-R7328P02.
Configuration restrictions and guidelines
When you patch software for a standalone device, 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 S12500-CMW710-R7328P02, you must use S12500-CMW710-SYSTEM-R7328P02H01.bin.
Configuration procedures
# Download the patch image file S12500-CMW710-SYSTEM-R7328P02H01.bin from the TFTP server to the root directory of the flash memory on the active MPU.
<Sysname> tftp 2.2.2.2 get S12500-CMW710-SYSTEM-R7328P02H01.bin
Press CTRL+C to abort.

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.

Configuration files
The system does not save the commands used in the configuration procedures to a configuration file.
Example: Patching software for an IRF fabric
Network requirements
As shown in Figure 2, the two-chassis IRF fabric and the TFTP server can reach each other. Each IRF member has one active MPU in slot 0 and one standby MPU in slot 1. The MPU in slot 0 of the master is the global active MPU. The members are running S12500-CMW710-R7328P02, and they have not been patched before.
Use the patch image file S12500-CMW710-SYSTEM-R7328P02H01.bin to fix bugs without rebooting the devices.
Software version used
This configuration example was created and verified on S12500-CMW710-R7328P02.
Configuration restrictions and guidelines
When you patch software for an IRF fabric, follow these restrictions and guidelines:
· The first time you install patch images, you must start with the global active MPU. For subsequent patch installations, you must start with the global standby MPUs.
· The patch image version must match the device model and Comware version. For example, to fix bugs in S12500-CMW710-R7328P02, you must use S12500-CMW710-SYSTEM-R7328P02H01.bin.
Configuration procedures
# Download the patch image file S12500-CMW710-SYSTEM-R7328P02H01.bin from the TFTP server to the root directory of the flash memory on the global active MPU.
<Sysname> tftp 2.2.2.2 get S12500-CMW710-SYSTEM-R7328P02H01.bin
