In this article, we take a look at how to configure High Availability Stateful Switchover (HA SSO) on the Cisco 9800 WLCs running IOS-XE using Redundancy Management Interfaces (RMI) in addition to the Redundancy Ports (RP).
In this article, we take a look at the initial configuration of a Cisco WLC 9800 and some recommended basic general settings that should be a part of most deployments.
In this article, we take a look at the building blocks of Catalyst 9800 WLAN Controllers configuration, which is very different from the older AireOS WLAN Controllers, and how to organize your configuration in such a way that makes it easier to work with over time.
In this article, we take a look at how to make ISE configure a switch port as a Trunk (using a Macro) when an Access Point in FlexConnect mode is connected to an 802.1x/MAB-enabled switch access port, and reverting the configuration back to an access port if the Access Point is unplugged.
In this article, we take a look at a strange error that can appear when you try to install a certificate in a Cisco WLC 9800, to use for features such as Web Admin or Web Auth guest portals.
In this article, we take a look at reducing the power used by some Cisco access point models, by disabling the built-in USB port, which is enabled by default on some latest models, like the C9120AXI. By powering off the access point, you can save a decent amount of PoE power-draw from your switches.
Debugging a troublesome wireless client isn’t always easy: the second you connect it to your SSID your WLC will output so much debug data that it’ll be hard to tell what is going on. Luckily, the Cisco TAC has developed an online tool you can upload your debug files to and get them translated into a somewhat easier to grasp format. Let’s see if it gets the job done!
In this article, we take a look at what happens when the certificates of your Cisco WLAN Controller (“WLC”) or its Access Points expire and run of time, and which workaround you can use to get your network up and running again.
Fast Transition 802.11r is finally being put to use in modern mobile devices and it will make them roam better than never before. check out this article to learn about the differences of the Fast Transition modes of operation.
Protecting your management access has never been more important and on a Cisco WLAN Controller the steps needed to do this has changed as time flies by, so in this article we take a look at what’s really going on when you apply an Access Control List (ACL) to a WLAN Controller CPU.
In this short article, we take a look at how to create a Redirection ACL on 9800 WLCs to use with Central Web Authentication for Cisco ISE guest access services and go through what each line of the ACL really does.
