Wireless LAN Controller Monitoring
WLC monitors may now be added to Wireless Lan Controllers running the Cisco IOS XE Operating System. Monitored devices will be polled periodically via https for a set of connected clients as well as some associated information, such as which Access Point each client is connected to. This allows for the querying of clients based on data points such as MAC, IP Address, or when the client was last seen. It also allows for the display of clients on Maps under their associated Access Point.
Configuration
-
Add your Wireless Lan Controller, and its associated Access Points to the inventory.
-
Ensure that their hostnames are correct, and that their Device Adapters are set to Cisco IOS.
Access Points reported from the Wireless Lan Controller will automatically be given an AP tag. This identification is based on both the Managed Network and Hostname of the device in inventory. So please make sure that the APs are in the same Managed Network as the controller and that the hostnames in inventory match the hostnames configured in the Controller.
- Make sure your Wireless Lan Controller has credentials configured for it in the Credential Manager.
VTY Username and VTY Password are used for authentication.
As the monitor starts polling, the access points will automatically receive the device tag “AP” (“Access Point”). Clients will also become visible under the new [Wi-Fi Clients] tab.
| Item | Description |
|---|---|
| Status | The following two types of icons are displayed: |
 Indicates that the client was connected while the WLC was last polled for updates. |
|
 Indicates that the client was not connected while the WLC was last polled for updates. |
|
| Icon | A customizable image used as the icon for the node representing the client on the map. Any image can be uploaded and set. |
| SSID | The SSID to which the client is, or was last, connected. |
| Access Point | Displays the name of the access point the client is, or was last, connected to. |
| Name | A name may be associated with a client to make it easier to identify in this table and in maps. |
| IP Address | The current or last known IP Address of the client. |
| IPv6 Address | The IPv6 address used by the client is displayed. |
| MAC | The MAC address of the client is displayed. |
| Last Checked | The last time the WLC was polled. |
| Last Seen | The last time the Client was connected while the WLC was polled for updates. |
Viewing Clients on a Map
Add your Access Points to a Map as Devices. Now that they have an AP tag, a new option will be available when editing each one.
Enable [Show client list] to display all clients under the Access Point.
The images and names of each client may also be customized in this view. When viewing clients on a Map, right click one and select [Edit Client].
WLC Error Messages
The following errors are possible when monitoring Cisco Wi-Fi devices with a WLC monitor:
No Response (Could not establish a connection to the API)
Connection cannot be established:
No Response (The API could not find the resource. This may be due to RESTCONFIG being disabled on the WLC)
Connection can be established, but RESTCONF is disabled. Enable RESTCONF to locate the resources.
