Then, you can see the runtime and system time on the controller, as well as the internal temperature. In addition, the 802.Ila and 802.11b/g networks can be seen to be up.(2) AP SummaryThe next functional area is the AP Summary, which shows the total number of 802.Ha/n and 802.11b/g/n radios present, as well as the number of devices that are up, and the number of devices that are down. You can click Detail for more information. Selecting Details for 802.11b/g/n radios will display a list of APs as shown in Figure 13.16.This list provides important information about the AP management status, the channel it is on and the power level. A power level of 1 indicates that the highest level of power specified for that country is being used. This power level can be modified by hovering over the blue arrow on the right and selecting Configure, as shown in Figure 13.7.After selecting Configure, you will be taken to the page shown in Figure 13-18, which allows you to set general parameters, including enabling or disabling the radio, availability of the lln parameter, antenna type, and antenna diversity.You can also get information on managing frame protection and performing WLAN reloads. WLAN reloading allows us to control which SSIDs are available for this AP.On the right side of the page, you can modify the RF channel assignment and the TX (transmit) power level assignment. The higher the power value is set, the lower the power level will be. For example, modifying the power value from 1 to 2 reduces the power by 50%. Modifying it to 3 reduces it to 25% and modifying it to 4 reduces it to 12.5%. The power value of each level is half of the previous level.You can also modify and edit the performance profileo Click PerformanceProfile to access a section where you can define RF values and thresholds.196 Child 13 Simple Network Configuration and Monitoring with Cisco ControllersValues page. In addition, on the Monitoring page, the Wireless link can be selected on the left side of the page, as shown in Figure 13.19. Figure 13-16 Radio Details
