![]() Issue the commands on each controller before they touch the network. Tip #2 – Configure HA with Controllers “Offline” I set the controllers side-by-side, open two sessions, and position the putty windows accordingly. Both use a micro-USB cable (I leave the bolts out of my WLAN Pi for easy access to the cable when I need it). I always carry multiple USB cables not only because they get torn up easily, but also because I always have my Ekahau Sidekick and WLAN Pi on me. Tip #1 – Console Into Both Controllers SimultaneouslyĬonnecting to both controllers is easy when you have more than one console or micro-USB cable. To start, there are a few things I’ve started to do recently that have helped tremendously. If you are adding a second controller to one that is in production, be sure to understand the requirements fully. This guide expects the use of IOS-XE 17.1.X or later and assumes you are pairing new controllers out of the box with no prior configuration. ![]() Previously, connecting controllers back-to-back via their RPs was fool proof this is still an option on the 9800s but is no longer best practice. The Cisco Embedded Wireless Controller GUI has to be used to configure and trigger network software upgrade (pre-download) using the desktop (HTTP) image download method. The embedded wireless controller CLI can only be used to set the mode for image download as desktop (HTTP). So, the Cisco Embedded Wireless Controller network in this example containing Cisco Catalyst 9115AX series and 9120AX series APs is a homogenous network. For example, the Cisco Catalyst 9115AX series AP and the Cisco Catalyst 9120AX series AP use the ap1g7 AP software image file. A homogenous Cisco Embedded Wireless Controller network is one which contains APs that have the same AP software image type. Note that the desktop (HTTP) method works only for a homogenous network. This downloaded bundle contains the AP and controller software images which need to be extracted to the computer or laptop desktop before they can be uploaded to the embedded wireless controller. Image download through desktop (HTTP) is applicable only in the network software upgrade (pre-download) scenario.įor the desktop (HTTP) method, download the software image bundle for the Cisco Embedded Wireless Controller to your computer or laptop desktop. ![]() The SFTP image download method also can be triggered using both the GUI and CLI. To download the software images from the SFTP server, in addition to the IP address of the SFTP server and the software image bundle path, you need to specify the SFTP server credentials. In the SFTP method, the AP and controller software images are stored on an SFTP server. The TFTP image download method can be triggered using both the GUI and CLI. To download the software images from the TFTP server, you need to specify the IP address of the TFTP server and the path to the software image bundle on the TFTP server. In the TFTP method, the AP and controller software images are stored on a TFTP server. These methods are based on the location from where the controller transfers the software image to the subordinate AP: In a Cisco Embedded Wireless Controller network, there are four ways in which the software image can be downloaded from the embedded wireless controller. ![]()
