A wireless LAN controller (WLC) is a network component that manages wireless network access points and allows wireless devices to connect to the network. It offers central control over network elements, increases network visibility, and greatly simplifies individual component monitoring. WLCs (Cisco WLC) are commonly used to gain control over your routers, switches, firewalls, gateways and other devices. Monitoring Cisco WLC helps you determine the performance and efficiency of every device and its associated peripherals discovered in OpManager. Show
Wireless LAN Controller Monitoring in OpManagerOpManager's multi-vendor WLC monitoring module allows you to keep your network intact by providing in-depth visibility of your wireless LAN controller (WLC), its associated service set identifiers (SSIDs) and access points (APs). Cisco's WLC monitoring tool in OpManager allows direct discovery of Cisco WLC and their associated SSIDs, APs and helps you monitor the overall performance of your wireless network with the help of Cisco WLC monitor. The WLC snapshot page provides inventory information, the device availability status, and other similar information. In addition, knowing the top five access points based on usage tells you who the top talkers are in your WLC environment, and custom dials display information on various parameters, including CPU and memory usage.  Advanced monitoring of Cisco WLC access pointsAdding more APs is an easy way to increase the reach of your company's wireless network. A WLC monitoring tool can simplify the tracking of all the access points in your network. OpManager automatically identifies the APs associated to the discovered WLC upon configuration and lists them under the dedicated Access Points tab. You can also enable advanced monitoring of your access points by discovering them in OpManager. The discovered access points will be monitored for availability and performance, just like any other device in OpManager, and the user will have complete control over it. Monitor WLC SSIDs, rogue SSIDs, and clientsAn unmonitored network is a major threat to a company. It allows hackers and unauthorized users with malicious intent to gain access to the network more easily. The Cisco WLC monitor tool in OpManager categorizes all the SSIDs and rogue SSIDs (hot spots and adhoc) in your network, and lists them under the dedicated SSID and Rogue SSIDs tabs respectively. If necessary, these rogue SSIDs can be discovered in OpManager and monitored individually. To leverage your network bandwidth effectively, you can view the number of employee devices connected to your network in the Clients tab. This helps in analyzing network usage and in capacity planning. You can also keep an eye on the real-time client count and network traffic using Discover Clients. Cisco WLC reports and dashboard viewsReports: With OpManager's WLC monitor, availability and health reports such as CPU Usage and Interface Traffic reports can be generated for the discovered WLC devices. Additionally, the access points that are discovered in OpManager (advanced monitoring enabled) will have full access to all types of reports based on the type of device. Dashboard views: The following dashboard views are currently available for the Cisco WLCs discovered in OpManager.

What is the service port on a WLC used for?The service port is used for out-of-band management of the controller and system recovery and maintenance in the event of a network failure. It is important to note that the service port does not support VLAN trunking or VLAN tagging and is therefore required to connect to an access port on the switch.
What is a service port Cisco?The service-port interface controls communications through and is statically mapped by the system to the service port. The service port can obtain an IPv4 address using DHCP, or it can be assigned a static IPv4 address, but a default gateway cannot be assigned to the service-port interface.
What is SP port in WLC?The Service Port is used for Out Of Bound (OOB) Management. Whilst the default configuration on the WLC allows for access via the management interface, it is better practice to have the service port configured on a different VLAN and use that to reach the WLC via SSH / HTTPS.
Which of the following are the protocol used for WLC to communicate with multiple connected APS in the network?CAPWAP. The AP and WLC connect with a tunneling protocol, the Control And Provisioning of Wireless Access Points (CAPWAP) tunneling protocol. CAPWAP encapsulates all data between the lightweight AP and the WLC.
