- The Devices table displays the total number
of devices in the
access pointmanaged network. The pie chart is a
proportional view of how many devices are functional and currently online. Green
indicates online devices and red offline devices detected within the managed
network.
- The Offline Devices table displays a list
of devices in the controller managed network that are currently offline.
The table displays the number of offline devices within each
impacted RF Domain. Assess whether the configuration of a particular RF Domain is
contributing to an excessive number of offline devices.
- The Device Types table displays the kinds
of devices detected within the system. Each device type displays the number currently
online and offline.
- Use the RF
Quality table to isolate poorly performing radio devices within
specific controller managed RF Domains. This information is a starting point to
improving the overall quality of the wireless controller managed network. The
RF Quality area
displays the RF Domain performance.
Refer to the following
table for details:
Worst 5 |
Displays five RF Domains with the lowest
quality indices in the wireless controller managed network. The value
can be interpreted as:
- 0-50 – Poor
Quality
- 50-75 –
Medium Quality
- 75-100 –
Good Quality
|
RF Domain |
Displays the name of the RF Domain wherein
system statistics are polled for the poorly performing device. |
- The System Security table defines a
Threat Level as an integer value indicating a potential
threat to the system. It is an average of the threat indices of all the RF Domains
managed by the access
point.
Threat Level |
Displays the threat perception value. This
value can be interpreted as:
- 0-2 – Low
threat level
- 3-4 –
Moderate threat level
- 5 – High
threat level
|
RF Domain |
Displays the name of the target RF Domain
for which the threat level is displayed. |
