48 Planning and Managing Your Wireless Network with WMS

Network Status

WMS provides summary status on devices in the network at the Mobility Domain, switch or AP level. View the
summary status as the initial step in monitoring. Summary status displays the operational status of WSSs, AP, and their
radios (whether they are up or down).
In addition, WMS collects network statistics for devices, including system-level events and statistics for the wired
network.
The Alerts panel at the bottom of the WMS window displays top-level status information. The Alerts panel provides you
with summary error and warning information for the following areas:
• Config—indicates network plan configuration issues
• Local changes—indicates changes in WMS that can be deployed to the network
• Network changes—indicates configuration changes in the network
• Alarms—shows the number and severity of alarms detected in the network

RF Monitoring

RF monitoring provides you with current and historical information about your radio health and activity.
Statistics collected for the RF environment provides data on a per-channel basis. You can view noise levels, cyclic
redundancy check (CRC) and PHY errors, packet retransmissions and percent utilization.
Data collected for the RF neighborhood displays the neighboring radios. This information can be viewed as a list of
radios heard by a particular radio, as well as a list of radios who can hear a particular radio.
You also can display trending information on a per-radio basis. Trending collects radio statistics and charts them on a
time basis. For example, you could display average throughput rates for the previous 30 days, week, or day. You can
display and print the charts from WMS, as well as generate a report.

Client Monitoring

Client monitoring provides current and historical information about the clients using your network, including client
activity, current client sessions, and the ability to locate clients at your site. WMS displays the data that WSSs collect on
user sessions—either for a single user, users associated with an AP, or users associated with a specific radio.
By viewing monitoring information for a user or a group of users, you can troubleshoot problems originating from
bandwidth constraints or roaming patterns. You can collect statistics and view reports about the following:
• Client associations, authentication, and authorization failures
• Client activity, such as roaming and successful authorization
• Current session status, location history, and statistics
• Specifics on users over a period of time; information can be gathered up to 30 days for session status, location
history, and client errors
If you use WLAN Management Software RF Planning, you also can display the approximate geographic locations of
clients.
