46 CHAPTER 2: PLANNING AND MANAGING YOUR WIRELESS NETWORK WITH 3WXM
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 3WXM, as well as
generate a report.
Client Monitoring Client monitoring provides current and historical information about the
clients using your network, including client activity, watch list clients,
current client sessions, and the ability to locate clients at your site. 3WXM
displays the data that WX switches collect on user sessions—either for a
single user, users associated with a MAP, users associated with a specific
radio, or users added to a watch list.
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 on:
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, client errors, and
client activity on users you place on the watch list
Rogue Detection A rogue AP is an access point that is not authorized to operate in or near
your network. You can use RF countermeasures to deny service to or
from a targeted rogue AP, and render them ineffective. Once a rogue AP
is detected and reported, the closest 3Com MAP is assigned to perform
RF countermeasures. By spoofing various 802.11 control messages, the
MAP’s countermeasures disrupt association and authentication attempts
to the rogue AP by any new clients. This also disrupts any active
communications between any existing client and rogue AP.
You can collect and statistics and view reports on:
Current rogue list, aggregated for the whole network
Current hour rogue list
Current day rogue list
30 days of rogue history, using best listener data
