Suppose that you have a large wireless network with several controllers, many APs, a RADIUS server, and a syslog server. A user has reported connectivity problems in a specific building location but has provided no details about the AP or controller he tried to join. Which one of the following is the most efficient troubleshooting method you can use to find information about the client?

Suppose that you have a large wireless network with several controllers, many APs, a RADIUS server, and a syslog server. A user has reported connectivity problems in a specific building location but has provided no details about the AP or controller he tried to join. Which one of the following is the most efficient troubleshooting method you can use to find information about the client?

• Go to the client’s location and use your own computer to associate with the network and then find out which AP and controller you are using
• Access each WLC and check the status of every AP that is joined to it
• Search for the client’s MAC address on each controller
• Search for the client’s MAC address on the RADIUS server

Explanation: Out of the possible answers, the most efficient method would be to access each controller and search for the user’s MAC address. That would give you important information specific to that user. You could also leverage Prime Infrastructure or DNA Center to search for the client across all managed controllers at once. If you choose to use your own computer, you may never be able to duplicate the conditions the user had when he experienced the problem. Checking each AP is not an efficient approach because you have not narrowed the scope of the problem. Checking the RADIUS server might reveal some authentication problems, but only if the user’s problem involved failed authentication.
