Troubleshooting Wireless Connectivity - Troubleshooting Wireless Connectivity From The WLC

4 important questions on Troubleshooting Wireless Connectivity - Troubleshooting Wireless Connectivity From The WLC

What are the 3 conditions a client must meet to join and use a wireless network?

1. Client is within RF range and asks to associate
2. Client authenticates
3. Client requests and receives an IP address.

In the Client View on a WLC, what do the 5 connectivity state dots stand for?

1. Start (Client activity just begun)
2. Association (Client has requested 802.11 authentication and association with an AP.)
3. Authentication (Client must pass Layer-2 PSK or 802.1X authentication policy.
4. DHCP (The WLC is waiting to learn the client's IP address from a DHCP server.)
5. Online (The client passen Layer 2 and Layer 3 policies, succesfully associated and can pass traffic)

In the WLC, what does the Connection Score represent?

It is a percentage of the current connection speed or data rate versus the lower maximum supported rate of either the client or the AP.

Which 4 client testing tools are available in the WLC and how do they work?

1. Ping Test (Send 5 ICMP Echo packets to the client's IP and measures response time)

2. Connection Test (WLC Debugs the client for up to three minutes and checks each policy step.)

3. Event Log (The WLC collects and displays a log of events. Very complex and detailed information, more suited for TAC)

4. Packet Capture (WLC Enables a wireless packet capture at the AP where the clients attempts to join. Data is saved to a specified FTP server.)
