Introduction

The following information provides an example for upgrading the software version of a centralized router through TFTP.

Prerequisites

The following information applies to Comware 9-based routers. Procedures and information in the examples might be slightly different depending on the software or hardware version of the routers.

The configuration examples 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.

The following information is provided based on the assumption that you have basic knowledge of TFTP.

Example: Using the device as a TFTP client to upgrade software

Network configuration

As shown in Figure 1, the host is connected to GigabitEthernet 0/0/1 of the router. The router acts as the TFTP client and the host acts as the TFTP server. Configure the network to realize software upgrade for the router through TFTP.

Figure 1 Network diagram

‌

Analysis

For the router to use the new software version after reboot, specify the software image file to be used at the next boot as the main startup image file.

Software versions used

This configuration example was created and verified on R9141P16 of the MSR2630E-X1 device.

Restrictions and guidelines

When you configure the device as a TFTP client to upgrade software, follow these restrictions and guidelines:

·     If storage space on the device is not enough for the upgrade, use the delete /unreserved file-url command to delete unnecessary files before performing software upgrade.

·     Before rebooting the device to complete the upgrade, use the save command to save the running configuration.

Procedures

Configuring the host

# Assign IP address 192.168.100.14/24 to the host. Make sure the host and the router can reach each other. (Details not shown.)

# Start the TFTP server on the host and configure TFTP server settings such as the download path. This example uses the 3CDaemon TFTP server.

Configuring the router

# Assign an IP address to GigabitEthernet 0/0/1 on the router.

<Router> system-view

[Router] interface gigabitethernet 0/0/1

[Router-GigabitEthernet0/0/1] ip address 192.168.100.66 255.255.255.0

[Router-GigabitEthernet0/0/1] quit

[Router] quit

# Verify that the router can ping the TFTP server.

<Router> ping 192.168.100.14

Verifying the IPE file and the images.....Done.

H3C xxx images in IPE:

  test-cmw910-boot-r9141p16.bin

  test-cmw910-system-r9141p16.bin

This command will set the main startup software images. Continue? [Y/N]:y

Add images to the device.

Decompressing file test-cmw910-boot-r9141p16.bin to flash:/test-cmw910-boot-r9141p16.bin.........Done.

Decompressing file test-cmw910-system-r9141p16.bin to flash:/test-cmw910-system-r9141p16.bin.................................Done.

The images that have passed all examinations will be used as the main startup software images at the next reboot on the device.

# Specify upgrade file test-old.ipe as the backup startup image file for the router.

<Router> boot-loader file cfa0:/test-old.ipe backup

This command will set the backup startup software images. Continue? [Y/N]:y

The images that have passed all examinations will be used as the backup startup

software images at the next reboot.

# Reboot the device.

<Router> reboot

Verifying the configuration

# Use the display version command to display system version information after device reboot.
