Clients This link ties you to a page that provides a list of clients and lets you search by MAC address for clients. RADIUS Servers This link provides a list of RADUIS Authentication and Accounting servers. Looking further into the 802.11a n Radios and 802.11b g n Radios options you can gain even more information by selecting the Details link for a radio from the Monitor Summary page. Here is what you get. You see the slot that the radio is in and the base radio MAC address. Looking more closely at Figure 13-19 you can see that Operational Status is UP. You can gain information regarding a load profile noise profile interference profile and coverage profile. Load Profile is set to 80 by default. If the load of this particular AP goes over that threshold Load Profile shows a warning rather than the status Passed. Likewise if the SNR is too low Load Profile indicates a warning. Should too much interference be on the same channel that this AP is operating on the Interference Profile shows a warning. If clients roam away and are not able to relay off another AP the Coverage Profile shows a warning. To see the details of these profiles from the screen in Figure 13-18 select the Details link at the right side of the page. This causes a page similar to Figure 13-20 to be displayed.

Numerous items are of interest here that are not seen in the figure Note To see the content discussed in the previous bulleted list you need to scroll down in the web interface of the controller because the page is long for this output and is not shown completely in Figure 13-20. The Noise vs. Channel chart shows each channel of the AP and the level of non-802.11 noise .
