Amelyorasyon Imaj Efikas

• 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.

Nòt: 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.

Aktive Pre-Telechaje (GUI)

• Step 1: Choose Configuration >Wireless > Access Points.
• Step 2: In the Access Points page, expand the All Access Points section and click the name of the AP to edit.
• Step 3: In the Edit AP page, click the Advanced tab and from the AP Image Management section, click Predownload.

Istwa Fonksyonalite pou Telechaje Imaj AP Deyò Band lan

• Tablo sa a bay lage ak enfòmasyon ki gen rapò ak karakteristik ki eksplike nan modil sa a.
• This feature is available in all the releases after the one in which it is introduced, unless noted otherwise.

Tablo 1: Istwa Fonksyonalite pou Telechaje Imaj AP Deyò Band lan

Lage	Karakteristik	Enfòmasyon sou Karakteristik
Cisco IOS XE Dublin 17.11.1	Telechaje Imaj AP Deyò Band lan	Metòd amelyorasyon imaj AP a amelyore pou fè amelyorasyon yo pi rapid e pi fleksib.

Enfòmasyon sou Telechaje Imaj AP Deyò Band lan

• Nan deplwaman WLAN yo, pwen aksè yo (AP) kolekte imaj lojisyèl yo ak konfigirasyon yo nan men kontwolè a (anndan band) pandan faz rantre, pre-telechaje, ak amelyorasyon sou chemen kontwòl CAPWAP la. Mekanis sa a gen limitasyon nan kontèks gwosè fenèt CAPWAP, pwosesis pake CAPWAP yo, ak telechajman imaj paralèl. Avèk amelyorasyon imaj ki se yon aktivite enpòtan nan sik lavi pwen aksè yo, amelyorasyon yo vin tounen yon aktivite ki pran anpil tan lè gwosè deplwaman an ogmante, sitou pou deplwaman a distans, paske imaj la toujou soti nan men kontwolè a, kèlkeswa kalite deplwaman yo.
• Pou fè amelyorasyon yo pi rapid e pi fleksib, metòd amelyorasyon imaj AP la amelyore nan vèsyon Cisco IOS XE Dublin 17.11.1 la. Yon metòd amelyore web Sèvè (nginx) k ap fonksyone sou kontwolè a ede telechajman imaj AP yo disponib deyò chemen CAPWAP la (deyò band).

Remak

• 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.

Restriksyon pou telechaje imaj AP deyò bann lan

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

Telechaje imaj AP a soti nan kontwolè a lè l sèvi avèk HTTPS (CLI)

Anvan ou kòmanse

• 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.

Etap 1	konfigirasyon tèminal Example: Aparèy # konfigirasyon tèminal	Antre nan mòd konfigirasyon mondyal la.
Etap 2	metòd amelyorasyon ap https Example: Device(config)# ap upgrade method https	Configures the corresponding AP to download the image over HTTPS from the controller if the AP supports the out-of-band AP image download method. You can check whether the AP supports efficient download method using the show ap config general kòmandman. Sèvi ak la non form of this command to disable the out-of-band AP image download method.
Etap 3	ap file-transfer https port port_number Example: Aparèy (konfigirasyon) # ap file-transfere pò https 8445	Konfigire yon pò pèsonalize pou telechaje imaj soti nan sèvè nginx k ap fonksyone sou kontwolè a. 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.

	Kòmand oswa Aksyon	Objektif
		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 transfè sou HTTPS olye de 8443. Port 8443 is customizable. A sampkonfigirasyon an bay anba a: Source= wireless controller Destination= Access Point Protocol=HTTPS Destination Port=8443 Source Port=any Description= “Out of Band AP Image Download”

Telechaje imaj AP a soti nan kontwolè a lè l sèvi avèk HTTPS (GUI)

Pwosedi

• Etap 1: Choose Configuration >Wireless >Wireless Global.
• Etap 2: Nan seksyon Mizajou Imaj AP a, aktive Metòd HTTPS la pou pèmèt telechaje imaj sou AP yo soti nan kontwolè a, atravè HTTPS. Sa a deyò bann file Transfè se yon metòd efikas pou amelyore imaj AP.
  Remak
  • The AP should support out-of-band image download. You can verify this in the Configuration >Wireless > Access Points window. Select the AP, and in the Edit AP > Advanced tab, view detay sou sipò a nan seksyon Jesyon Imaj AP a.
• Etap 3: Antre pò HTTPS la pou deziyen AP a file transfè sou pò sa a. Valè valab yo varye ant 0 ak 65535, ak valè defo a se 8443. Remake byen ke ou pa ka itilize pò 443 pou AP. file transfè paske se pò pa default pou lòt demann HTTPS yo.
  • By default, the Efficient AP image download feature uses port 8443 for HTTPS. If the same port is configured for HTTPS access for the 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 transfè sou HTTPS olye de 8443.
• Etap 4: Klike sou Aplike sou Aparèy la pou sove konfigirasyon an.
