In the WLAN advanced tab, there are other options and parameters that provide us with more options to configure WLAN. Some of these advanced features are set by default and some of them we can configure as per our requirements. These advanced features include QOS, Policy-Mapping, and other advanced parameters.
In this Blog, we will discuss about WLAN advanced parameters and their uses, what is use of those parameters is, when we should use which parameters, and How to Configure advanced Wi-Fi settings.
Configure WLAN advanced Wi-Fi settings
WLAN QoS Tab
QOS
In the QoS (Quality of Services) tab, we can configure the priority of the WLAN or Traffic.
To go to this tab- click on WLAN–>Click on SSID–>click on the QoS profile tab.
Quality of Service Level includes:
- Platinum (voice)—Assures a high Quality of Service for Voice over Wireless.
- Gold (video)—Supports the high-quality video applications.
- Silver (best effort)—Supports the normal bandwidth for clients.
- Bronze (background)— Supports the lowest bandwidth for guest services.
We can configure are QoS based on our requirement or we can keep as default as well.
Policy-Mapping
If we need to apply any local Policy to WLAN, then we can create a local Policy in WLC and apply it to the WLC.
To create a local policy, choose Security > Local Policies > New.
WLAN Advanced Options
There are multiple other parameters to be configured or kept as default settings. Here we will discuss about some major or important field
-
Allow AAA override
This is a global parameter that we can enable or disable based on our requirements.
If we enable this feature and if users have both options to authenticate, such as with the AAA server and WLAN Authentication parameter, then client authentication will prefer the AAA server.
With this option enabled, All client Authentication moves from the default Cisco WLAN VLAN to a VLAN returned by the AAA server which is already configured in the Cisco WLC interface configuration.
To use this option, we have to add/configure / Integrate the AAA server with WLC. To add an AAA server in WLC use the below path:
Security–>AAA–>Radius / TACACS+
Let’s understand with an example, if the AAA override option is enabled then If the Corporate WLAN primarily uses a Management Interface assigned to VLAN 20, and if AAA Override returns a redirect to VLAN 10, the operating system redirects all client transmissions to VLAN 10.
If AAA Override is disabled, then all client authentication will use the default WLC authentication parameter configured for that WLAN.
The rest of the Options you can keep as default.
Flex-Connect
The next major Parameter is Flex Connect.
Let’s have some overview of flex-connect technology to understand this tab.
“If any organization has branch offices in multiple cities, and if they want to connect Branch office Wi-fi AP /Users to Centralised WLC in the Data Centre at HQ and want to control all data traffic from DC only. Then we can configure AP as Flex-Connect with Local switching. Flex-Connect is also called H-REAP, but H-REAP has been replaced with Flex-connect”.
To configure Flex-Connect, need to configure that Access Point (AP) as flex connect mode first.
In Flex-Connect, there is a concept called Local Switching and Central Switching.

Local Switching: If we enable Local Switching, then all user’s local traffic will be switched locally to the branch and will not go to WLC over the WAN link.
Central Switching: If we uncheck the Flex-connect Local switching option, then all user’s traffic or data will go to WLC every time over WAN, which can consume WAN link bandwidth.
So, to use a flex-connect feature for that WLAN, need to check the Flex-connect Local Switching option in WLAN Advanced tab.
Wifi-ax BSS
- Another parameter to enable 802.11x or Wifi-6 features in WLAN Advanced tab.
Now this option has been added after 802.11ax was introduced.
802.11ax supports MU-MIMO and OFDMA features and all these features are enabled by defaults. You can un-check these options as well, but recommended is it keep as default settings.
There are other features for editing the WLAN:
These features are available on the edit button. By these buttons, we can:
- Remove the WLAN
- Configure WLAN as mobility Anchors for that WLC
- Configure 802.11U
- Foreign maps
- Service Advertisement
- Hotspot 2.0
Conclusion:
From the WLAN advanced tab, we can edit, modify, configure, manage and remove the WLAN/SSID. There are multiple parameters that we can opt/configure based on our requirements from this WLAN Advanced Tab under WLAN tab in Cisco WLC.
