WiFi - 6E - SSID not showing in 6GHz but showing in 2.4GHz and 5GHz by Ulises Cázares

 Hi, the other day I was testing an Aruba AP 635 configuring an SSID to show in the 3 bands and apparently everything looked fine because I connected my laptop to the SSID but after a few connections and reconnections I noticed the laptop only connected either to the 2.4GHZ and 5GHz SSIDs but never to the 6GHz. 

Reviewing the configuration of the AP, I made sure the 6GHz radio was enable  so something else should be the problem.

After reading about requeriments for 6GHz I noticed that WPA3 is Mandatory and my mistake was that I had configured the security as WPA2 which is not allowed in 6GHz. Once I changed it to WPA3 my laptop  was able to connect in the 6GHz radio.


So whenever you're working with a 6GHz SSID make sure the following is configured:

Security must be: WPA3-PSK or WPA3 Enterprise and for an open SSID you must use Enhanced Open so the packets are encrypted between the client and the AP.


Hope this helps

 Hi this is a step by step on how to configure an SSID in a functional Cisco WLC (8.10)  for Guest Authentication and MAC Caching using Aruba Clearpass General Steps (this guide assumes you have correctly configured the Clearpass side) Create an Authentication Server (The secret is the same as the one configured in Clearpass) Create an Accounting Server (The secret is the same as the one configured in Clearpass) Configure the WebAuth login Page (use the configured guets login page in Clearpass) Make sure the Web Auth Certificate points to the virtual IP in the WLC Create the FlexConnect Access List (or IPV4) Make sure WebAuth SecureWeb is enable Configure the SSID with the appropiate settings   1.- Create an Authentication Server 2.- Create an Accounting Server  3.- Configure the WebAuth login Page (in this example is; guest.demo-clearpass.net/cisco_login.php)  Note.- In order to avoid the security warnings in the conencting devices, install the appropiate certificate in Clearpass wit

Using API in ArubaOS Switches with Postman by Ulises Cázares

 Hi, today I'm gonna show how to interact with the Aruba OS version 16.10 switches API using postman. My intention is that you know how to construct the request using headers, parameters and the body of the request. The first things to start working with the switch API are: to have administrative access to the device and to make sure of the switch version so you can look for the appropiate document. Remember, APIs can change form version to version.  You can use the command: show version. In my case is 16.10 Then you can make a quick search in google like "Aruba switch 16.10 API" to get the document and find out what are the option provided in the API. In the document you will find examples using curl and that's why i'm writting this in postman, so you have options. Now, let's do 4 thing so you can use the API: Make sure the REST interface is enable or enable it Login to the device API Construct a GET request Construct a POST request  Make sure the REST inter

WiFi - How to know supported channels by a wireless client by Ulises Cázares

Image
 Hi, in this post I would tell you how to be sure which WiFi channels are supported by a wireless client so we can configure wireless solutions that will work with the endpoints in the environment. I normally approach this topic in 2 ways 1. Directly in the wireless client This one is the obvious option but, in my experience, the majority of wireless clients don't show that in any part of the configuration. Because wireless clients are very different and their configurations menus too there's no way to show a "common" path to see the supported channels(if the wireless client shows them)   2.- Use a wireless adapter in monitor mode and wireshark to see an Association Request paquet from the client. In the following images we'll see where in the association request we can see that information.    The fastest way to do it is to follow these steps: Put the wireless adapatar in monitor mode in the AP channel we'are going to connect the wireless client Open wireshar
