Example: Configuring AP image downloading

Introduction

The following information provides an example for 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.

Figure 1 Network diagram

 

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

View the current software version of the AC.

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.

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

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
