Introduction

The following information provides an example for configuring AP image downloading.

Prerequisites

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

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 AP management and software upgrade.

Example: Configuring AP image downloading

Network configuration

As shown in Figure 1, the AC is attached to the Layer 2 switch in hair-pin mode. The Layer 3 switch acts as the DHCP server to assign IP addresses to APs and the Layer 2 switch supplies power to APs through PoE. Configure AP image downloading to reduce time consumed by AC and AP upgrade.

Restrictions and guidelines

·     Before restarting the AC, save the running configuration.

·     Make sure all APs to be upgraded are online when you configure the AC to deploy the image to APs.

·     Typically, the system can deploy an image to 500 to 1000 APs per hour. Reserve sufficient time for image downloading.

·     If an AP goes offline during image downloading, the downloading process for the AP is terminated. To upgrade the AP, you must configure the AC to deploy an image to the AP manually after the AP comes online.

Procedures

Configuring the AC

1.     View the current software version of the AC.

<AC> display version

H3C Comware Software, Version 7.1.064, Release 5446

Copyright (c) 2004-2021 New H3C Technologies Co., Ltd. All rights reserved.

H3C WX5580H uptime is 0 weeks, 0 days, 20 hours, 51 minutes

Last reboot reason : User soft reboot

2.     Configure the AC to download the image file and specify the file as the next startup configuration file:

# Configure the AC to download the image file. In this example, the TFTP server address is 192.168.0.1 and the image file name is test.ipe.

<AC> tftp 192.168.0.1 get test.ipe

Press CTRL+C to abort.

Writing file...Done.

# Specify the file as the main next startup configuration file.

<AC> boot-loader file cfa0:/test.ipe all main

3.     Deploy the image to all online APs.

<AC> system-view

[AC] wlan ap-image-deploy all

4.     View information about image downloading:

# Display AP image downloading information, including the downloading progress, time consumed, and the numbers of APs to be upgraded, succeeded APs, ongoing APs, and failed APs.

[AC] display wlan ap statistics image-download

Completed : 50%

Time consumed : 03min 58s

Max. concurrent image downloads APs : 416

AP count:

 Total to download : 20

 Success : 9

 In-progress : 10

 Failed : 1

# Display APs that have failed to download images.

[AC] display wlan ap statistics image-download failed

AP name                    Failure reason

ap2                        Tunnel down

# Resolve the issues that caused the failure. In this example, make AP 2 come online again.

# Re-deploy the image to the APs that have failed to download images.

[AC] wlan ap-image-deploy name ap2

5.     Save the running configuration and restart the AC and APs:

# Verify that all APs have obtained the image. Then, save the running configuration.

[AC] save startup.cfg

The current configuration will be saved to cfa0:/startup.cfg. Continue? [Y/N]:y

cfa0:/startup.cfg exists, overwrite? [Y/N]:

Saving configuration cfa0:/startup.cfg.Please wait...

Configuration is saved to device successfully.

[AC] quit

# Restart all APs and restart the AC at the same time.

<AC> reset wlan ap all

Reset APs that have established or are to establish primary tunnels with the AC. Continue? [Y/N]:y

<AC> reboot

Start to check configuration with next startup configuration file, please wait.........DONE!

This command will reboot the device. Continue? [Y/N]:y

Now rebooting, please wait...

Verifying the configuration

# Verify the AC version.
