Monitoring Mobility Express Network

Viewing Network Summary

The Monitoring service enables the primary AP to monitor the Cisco Mobility Express network.

Monitoring Dashboard

The monitoring dashboard of the Network Summary page displays count of the following:

  1. Wireless Networks

  2. Access Points

  3. Active Clients in 2.4 GHz and 5GHz

  4. Rogues AP and Clients

  5. Interferers


    Note

    Rogues and interferers are not clickable link. Only the count is displayed.

The Network Summary page has five customizable widgets representing data in both tabular and graphical formats for the following:

  1. Access Points (by usage)

  2. Clients (by usage)

  3. Applications (by usage)

  4. Operating System (by clients)

  5. Top WLANs (by usage)


Note

The widgets under Network Summary shows aggregate data for the wireless network.

Viewing Wireless Dashboard

The Wireless Dashboard provides details of AP and client performance.

Viewing AP Performance

The AP Performance dashboard helps the user to identify and troubleshoot the issues in the Mobility Express.



To access AP Performance dashboard, choose Monitoring > AP Performance.

The AP Performance dashboard displays the following charts:

  • Channel Utilization Top APs—Level of traffic including data and interference over the channel that is assigned on the AP. Interference includes both Wi-Fi and non Wi-Fi signals. High utilization of channel, for example above 50%, suggests high level of interference including noise from nearby APs/clients/rogues on the same channel which results in poor client performance.

  • Client Load TOP APs—Load indicator displays current number of connected clients on each access point. Higher load may impact performance, using client load balancing you can improve client distribution on the wireless network.

  • Interference Top APs—RF interference involves unwanted, interference of RF signals that disrupt normal wireless operations, that creates potential network latency and poor client performance. Interfering RF signals includes both Wi-Fi and non Wi-Fi signals.

  • Coverage BOTTOM APs—Coverage holes are areas where clients cannot receive a signal from the wireless network. A coverage hole is considered to have occurred when client SNRs falls below a predetermined level. A coverage hole event is when several clients are stuck in the same coverage hole.

Viewing Client Performance

The Client Performance dashboard helps the users to determine the cause of connection failure to the Mobility Express network and troubleshoot client related issues.

To access Client Performance dashboard, choose Monitoring > Client Performance.

The Client Performance dashboard displays the following charts:

  • Signal Strength—Strong signal strength results in more reliable connections and higher speeds. Signal strength is represented in -dBm format, ranges from 0 to -100dBm. The closer the value to 0, the stronger the signal. Click to get a summary of clients.

  • Connection Rate—Each client's throughput varies depending on the data rate used (802.11 a/b/n/ac) at any time, and this data rate may vary every second. Various factors such as RSSI values, RF interference, and so on, may affect a client device's instantaneous data rate.

  • Signal Quality—Signal-to-noise ratio (SNR) is the power ratio between the signal strength and the noise level. This value is represented as a +dBm value. In general, you should have a minimum of +25dBm signal-to-noise ratio. Lower values than +25dBm result in poor performance and speed.

  • Client Connections—Shows clients associated with the access points, of any connectivity types.
