3. Select the target evaluation task.
4. Click Resume.
Setting global thresholds
You can set global thresholds for evaluation indexes. WSM uses the evaluation indexes to evaluate
APs and clients and display some of the pie charts for overall evaluation information.
To set global thresholds:
1. Click the Service tab.
2. From the navigation tree, select WLAN Manager > Network Evaluation.
The Task List page displays all evaluation tasks.
3. Click Set Global Threshold. The Global Threshold Settings page appears.
4. Set thresholds for high-rate packets. Packets whose rates are higher than the configured
thresholds are high-rate packets. WSM uses the number of high-rate packets to calculate the
high-rate packet ratio.
a. Click the Setting link for High-Rate Packet Settings.
b. Select a threshold for each of the following indexes:
− 802.11a Packet Rate (Mbps)
− 802.11an Packet Rate (Mbps)
− 802.11b Packet Rate (Mbps)
− 802.11g Packet Rate (Mbps)
− 802.11gn Packet Rate (Mbps)
If the rate of packets sent by the corresponding type of radio reaches the threshold, the
packets are considered as high-rate packets.
c. Click OK.
5. Set thresholds for AP evaluation indexes. WSM uses the thresholds to evaluate APs' operating
status in an evaluation task. You can view the evaluation results in overall AP evaluation
information in the evaluation report.
a. Click the Setting link for AP Evaluation Index Settings.
b. Enter a threshold for each index.
WSM has defined the following threshold levels for each index: Excellent, Good, Fair, and
Poor. You can enter a value as needed for each level (The evaluation result of the data that
does not reach the Fair level is considered as Poor). When the data of an AP reaches a
level, the evaluation result for the index is of the corresponding level.
The indexes include:
− High-Rate Outgoing Packet Ratio (%)—Number of high-rate packets sent by an AP to the
total number of packets sent by the AP.
− High-Rate Incoming Packet Ratio (%)—Number of high-rate packets received by an AP to
the total number of packets received by the AP.
− Average Number of Online Clients—Average number of online clients of an AP.
− Incoming Packet Error Ratio (%)—Number of error packets received by an AP to the total
number of packets received by the AP.
