Figure 119 Channel Metrics for the 5 GHz Radio Channel
Channel Metrics shows the information displayed in the channel metrics graph.
Column Description
Channel A 2.4 GHz or 5 GHz radio channel.
Quality(%) Current relative quality of selected channels in the 2.4 GHz or 5 GHz radio bands, as
determined by the percentage of packet retries, the current noise floor, and the duty
cycle for non Wi-Fi devices on that channel.
Availability(%) The percentage of the channel currently available for use.
Utilization(%) The percentage of the channel being used.
WiFi Util(%) The percentage of the channel currently being used by Wi-Fi devices.
Interference Util(%) The percentage of the channel currently being used by non Wi-Fi interference + Wi-Fi
ACI (Adjacent Channel Interference)

Spectrum Alerts
When a new non Wi-Fi device is found, an alert is reported to the Virtual Controller. The spectrum alert messages
include the device ID, device type, IP address of the spectrum monitor or hybrid AP, and the timestamp. Virtual
Controller reports the detailed device information to AMP.
Configuring Spectrum Monitors and Hybrid IAPs
AnIAP can be provisioned to function as a spectrum monitor or as a hybrid IAP. The radios on groups of APs can be
converted to dedicated spectrum monitors or hybrid APs via the AP group’s 802.11a and 802.11g radio profiles.
Converting anIAP to a Hybrid IAP
You can convert all IAPs in an Instant network into hybrid IAPs by selecting the Background spectrum monitoring
option in the 802.11a and 802.11g radio profiles of an IAP. APs in Access mode continue to provide normal access
service to clients, while providing the additional function of monitoring RF interference. If any IAP in the Instant
network does not support the spectrum monitoring feature, that AP continues to function as a standard IAP, rather
than a hybrid IAP. By default, the background spectrum monitoring option is disabled. In the hybrid mode, spectrum
monitoring is performed only on the home channel.
You can convert IAPs in an Instant network to hybrid mode using the Instant UI or CLI.
