RingMaster Management Guide - Juniper Networks

Locating A User
Monitor Function
Display a user’s approximate location by doing the following:
1. On the Find Client(s) Result screen, click the Locate Client task (under Manage).
RingMaster retrieves information about a client’s location and adds an icon on the floor plan.
2. If three or more APs have not detected the client within 15 seconds of each other, the
Select Listeners dialog box appears, displaying a list of APs that have detected the client.
You can select up to six APs from this list. RingMaster uses selected APs to calculate the
location of a client.
3. RingMaster displays the approximate location of the client on the floor plan. The client’s
location is indicated with a laptop icon.
4. To refresh the list of APs that detect the client, click the (Refresh Listeners) button
5. To change the APs used for calculating the client’s location, click the Listeners tab and select
or deselect APs from the list, then click the
Refreshing Client Data
(Locate) button.
RingMaster refreshes client monitor data at regular intervals (every 15 minutes by default).
The administrator can specify the refresh rate using the client monitor polling interval.
(See Monitoring Settings.) Click the Refresh icon to refresh data on demand. Counters are
incremented each time the RingMaster Services receives a client activity trap generated by an MX.
Counters represent activity for all clients within the selected scope.
Performing an RF Link Test
Running an RF Link Test can provide a quick, simple summary and breakdown of basic RF statistics
for troubleshooting wireless performance problems. When an RF Link Test is started, it sends 20 null
data packets from the associated AP to the client.
This returns the following information:
❑ Number of null data packets sent
❑ Number of null data packets received and acknowledged
❑ Transmission time for each null packet
❑ Indication of signal strength relative to the AP
❑ Signal-to-noise ratio (SNR)
