The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

You can customize the Network Summary view by adding or removing widgets. The data displayed in the various widgets can be viewed either in the doughnut format or in the tabular format by toggling the display icon on the top right corner of the individual widgets.
You can view and manage WLAN users only for WPA2 Enterprise with Local Server setup. To use your Cisco Mobility Express wireless network, a wireless client should connect to a WLAN in the network. To connect to a WLAN, the wireless client will have to use the user credentials set for that WLAN. If this WLAN uses WPA2-Personal as a Security Policy, then the user must provide the appropriate WPA2-PSK set for that WLAN on the Controller AP. If the Security Policy is set to WPA2-Enterprise, the user must provide a valid user identity and the corresponding password set in the RADIUS user database.
You can set up different users (and consequently, user credentials) for the different WLANs in the Cisco Mobility Express wireless network, in the WLAN Users window. These are local users authenticated by the master AP using WPA2-PSK. Users authenticated by WPA2-Enterprise must have a valid record in the RADIUS database in order to be authenticated since they are not a part of the WLAN Users database.
Tip | The total number of active WLANs is displayed at the top of the page. If the list of WLANs spans multiple pages, you can browse these pages by clicking the page number links or the forward and backward icons. |
Step 1 | Choose
.
A count of the configured WLANs is displayed in the Wireless Networks summary window. |
Step 2 | In the
Wireless
Networks summary window, click the status icon or count display
icon to view high-level details of the corresponding WLAN, such as the
Active status,
Name,
Security
Policy, and
Radio
Policy.
You can also add new WLANs from this page. For details, see Adding a WLAN. |
The Mobility State graphic for a client shows the following details:
Name of the wireless LAN controller, with it's IP address and the model number of the AP on which it is running.
Name of the AP through which the client is connected to the controller, along with the type of connection (for example, Flexconnect), the AP's IP address, and the AP's model number.
Nature of connection between the AP and the client. For example, wireless 802.11n 5 GHz connection.
Name of the client, type of client (for example, Microsoft Workstation), VLAN ID of the client, and the client's IP address.
You can perform a ping test on the client to determine the latency or delay between the controller and the client. This is an Internet Control Message Protocol (ICMP) based test. Using the ping test you can know the connectivity as well as the latency between the controller and the client.
To start the test, click Start. The latency in milliseconds is represented graphically.
Note | This feature does not work on subordinate APs having Cisco AP-OS, namely the Cisco Aironet 1810W, 1830, 1850, 2800, and 3800 Series access points. |
The Client Packet Capture feature allows network administrators to capture packets flowing to, through, and from an AP, while the AP continues to operate normally. The packets are captured and exported to an FTP server, where you can do an offline analysis by using a tool such as Wireshark. This feature facilitates troubleshooting by helping to gather information about the packet format, application analysis, and security.
Packet capture can be enabled for only one client at a time.
The packets are captured and dumped in the order of arrival or transmission of packets, except for beacons and probe responses. The packet capture contains information such as channel, RSSI, data rate, SNR, and timestamp. Each packet is appended with additional information from the AP.
A file is created on the FTP server for each AP based on AP name, controller name and timestamp.
If the FTP transfer time is slower than the packet rate, some of the packets may not appear in the capture file.
If the buffer on the AP does not contain any packets, a dummy packet is dumped to keep the connection alive.
If the FTP transfer fails or FTP connection is lost during packet capture, the AP stops capturing packets, notifies with an error message and SNMP trap, and a new FTP connection is established.
Not all packets in the air are captured, but only those that reach the radio driver.
Before you start ensure that you have an FTP server, that is reachable by the AP. The captured packets are dumped to this FTP server.
Choose Monitoring > Network Summary > Clients.
On the Client View page, under Client Test, click the Packet Capture tab.
Click Start.
The Client Status icon is Green when a packet capture is in progress. It is Red otherwise.
