MSM7xx Controllers Configuration Guide v6.4.0

◦ L: Legacy radio. Any radio that does not support RRM. (For example, the MSM3xx series.)
◦ M: Monitor mode. Radio is operating in monitor mode.
◦ S: Sensor mode. Radio is operating in sensor mode.
◦ U: Uncontrolled. An radio that is not controlled by this controller. In IDS it is known as
an External or Rogue radio.
• Last detected: Date and time when the radio was last known to be active in the RF environment.
(The date and time that a beacon from the radio was received by a controlled AP.)
• Band: Frequency band in which the radio is operating: 2.4 GHz band (for 802.11b/g/n) or
5 GHz band (for 802.11a/n, 802.11ac/n).
• Channel: Main channel on which the radio is operating. Hover your mouse pointer over the
yellow triangle to get more information if there is a difference between the planned and
operating channel.
• Power: Radio’s transmission power. Hover your mouse pointer over the yellow triangle to
determine the reason for the difference between planned and operating power.
• SSIDs: Count of SSIDs. Hover your mouse pointer over the count to see the list of SSID names.
• Neighbors: Number of radios seen as neighbors by this radio. If the value is not available,
“N/A” is displayed. Two radios are considered to be neighbors if either radio can detect
frames (beacon frames, typically) transmitted by the other. Normally, RF propagation between
two radios is symmetric. However, this may not be the case if the two radios use different
transmit power, or if a noise source close to one radio is interfering with signals from the
other, especially when signal levels are weak. All neighbors are listed, even those at very low
power.
• Utilization: The average number of clients that were associated with the radio during the last
hour.
• IDS: IDS classification. To change a classification manually, select Controlled APs >> Security
> Neighborhood.
◦ Authorized: A controlled radio, or a radio marked as authorized by the administrator.
These radios are expected to be active and connected to the network.
◦ External: A radio operating in the area, but not marked as authorized by the administrator.
For example, an radio on an AP belonging to another nearby company. .
◦ Rogue: An AP that is connected to the network, but is not supposed to be there.
◦ Unclassified: Temporary state. The radio has been detected and is in the process of being
classified as either External or Rogue.
• Interferance
Green: No interference.◦
◦ Grey: Unknown.
◦ Yellow: Interference detected. A neighbor of the AP has switched channels because of
interference and there is a risk of performance impact.
◦ Red: Interference was detected that impacted performance. The AP has switched channels.
Configuring and conducting RRM analysis
Select Controlled APs >> Radio management > RRM to configure and manage RRM analysis options.
