− Description—Detailed description for the syslog.
− Time—Time when the syslog is received.
11. Analyze the RF ping results.
During the troubleshooting process, WSM performs RF ping tests on the client, and displays the
RF ping data in the RF Ping Result area until the tests are completed.
RF ping result list contents
{
No.—Sequence number of the RF ping packet.
{
Rate (Mbps)—Transmission rate of the test packets, in Mbps.
{
TxCnt—Number of transmitted packets.
{
RxCnt—Number of received packets.
{
RSSI—RSSI of the client, indicating the signal strength received by the client. A higher RSSI
indicates a stronger signal.
{
RTT (ms)—Response time to the packets, in milliseconds.
WSM performs an RF ping test on a client every 5 seconds, with a total of 5 tests. After the tests
are completed, the RF Ping Result area displays a conclusion for the wireless link status,
including failed, very poor, poor, good, and excellent. If the link status is very poor or poor,
view the spectrum analysis information to find out the problem.
12. View spectrum analysis information.
IMPORTANT:
To view the spectrum analysis information, make sure all the following conditions are met:
• The AP supports the spectrum analysis function and operates in hybrid mode.
• Spectrum analysis is enabled on both the AC and the radio of the AP.
• A spectrum analysis license has been installed on the AC.
To view the spectrum analysis information:
a. Click Spectrum Analysis.
b. Click Spectrum Analysis Monitor.
c. The Spectrum Analysis Monitor window appears, displaying the spectrum analysis
information, such as channel usage, channel usage trend, channel quality, and channel
quality trend, about the AP with which the client associates. For more information, see
" Managing spectrum analysis monitor ."
d. View the interference devices.
The interference device list displays all interference devices detected by the AP with which
the client associates.
Interference device list contents
− Interference Type—Interference device type, such as microwave oven or Bluetooth device.
− Sensitivity—Severity level of the interference caused by the interference device. Options
are integers from 0 to 100. A higher value indicates a severer interference.
− RSSI—Received signal strength indicator.
− Duty Cycle (%)—Duty cycle of the interference. Duty cycle is the time when the
interference device was active. You can view the duty cycle on the device.
− Affected Channel—Channel affected by the interference device.
