Nkwalite onyonyo nke ọma

• Efficient Image upgrade is an efficient way of pre-downloading the image to the APs. It works similarly to – subordinate model. An AP per model becomes the primary AP and downloads the image from the controller through the WAN link. Once the primary AP has downloaded the image, the subordinate APs start downloading the image from the primary AP. In this way, WAN latency is reduced. Primary AP selection is dynamic and random. A maximum of three subordinate APs per AP model can download the image from the primary AP.

Mara: Do not enable this feature on controllers running Cisco IOS XE Amsterdam 17.3.x when there are Cisco Catalyst 9124AX and Cisco Catalyst 9130AX APs in the same group.

Rịba ama

• HTTPS configuration done at the global level applies to all the APs joining the controller.
• When AP image download over an Out-of-Band method fails, the download falls back to the CAPWAP method, as a result of which the APs will not be stranded.
• AP image download over HTTPS may fail if the HTTPS server Trustpoint has a chain of CA certificates.
• Before you downgrade from Cisco IOS XE Dublin 17.11.1 to an earlier version, ensure that the Out-of-Band AP Image Download feature is disabled, as it is not supported in previous releases.

Mmachibido maka nbudata onyonyo AP na-apụ apụ

This feature is not supported on the following platforms:

• Cisco Embedded Wireless Controller on Catalyst Access Points
• Cisco Embedded Wireless Controller on Catalyst Switches
• Cisco Wave 1 Access Points

Budata onyonyo AP site na njikwa iji HTTPS (CLI)

Tupu ịmalite

• HTTPS configuration must be enabled.
• The NGINXx server must be running on the controller. Use the show platform software yang-management process command to check whether the nginx server is running.
• The custom-configured port must be reachable between the controller and the corresponding AP.

For the HTTPS port, the valid values range from 0 to 65535, with a default of 8443. You cannot use port 443 for AP file transfers because it is the default port used for other HTTPS requests. Also, avoid configuring standard and well-known ports because the configuration may fail.

	Iwu ma ọ bụ Omume	Ebumnuche
		By default, the Efficient AP image download feature uses port 8443 for HTTPS. If the same port is configured for HTTPS access for controller GUI, then GUI access will not work. In such instances, use a port number other than 8443 for controller GUI Access or configure a different port for AP file nyefee HTTPS kama 8443. Port 8443 is customizable. A sample config nyere n'okpuru: Source= wireless controller Destination= Access Point Protocol=HTTPS Destination Port=8443 Source Port=any Description= “Out of Band AP Image Download”
