Configuring Spectrum Monitors And Hybrid Iaps; Converting An Iap To A Hybrid Iap; Converting An Iap To A Spectrum Monitor - Aruba IAP-335 User Manual

Configuring Spectrum Monitors and Hybrid IAPs

An IAP can be provisioned to function as a spectrum monitor or as a hybrid IAP. The radios on groups of IAPs
can be converted to dedicated spectrum monitors or hybrid IAPs through the IAP group's 802.11a and
802.11g radio profiles.

Converting an IAP 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. IAPs 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 IAP 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. In other words, if the IAP-
channel width is 80 Mhz, spectrum monitoring is performed for 80 Mhz. If the channel width is 40, spectrum
monitoring is performed for 40 MHz channel. In a dedicated air monitor mode, IAPs perform spectrum
monitoring on all channels.
You can convert IAPs in an Instant network to hybrid mode by using the Instant UI or the CLI.
In the Instant UI
To convert an IAP to a hybrid IAP:
1. Click the RF link on the Instant main window.
2. In the RF section, click Show advanced options to view the Radio tab.
3. To enable a spectrum monitor on the 802.11g radio band, in the 2.4 GHz radio profile, select Enabled from
the Background Spectrum Monitoring drop-down list.
4. To enable a spectrum monitor on the 802.11a radio band, in the 5 GHz radio profile, select Enabled from
the Background Spectrum Monitoring drop-down list.
5. Click OK.
In the CLI
To configure 2.4 GHz radio settings:
(Instant AP)(config)# rf dot11g-radio-profile
(Instant AP)(RF dot11g Radio Profile)# spectrum-monitor
To configure 5 GHz radio settings:
(Instant AP)(config)# rf dot11a-radio-profile
(Instant AP)(RF dot11a Radio Profile)# spectrum-monitor
Converting an IAP to a Spectrum Monitor
In spectrum mode, spectrum monitoring is performed on entire bands and the IAP functions as a dedicated
full-spectrum RF monitor, scanning all channels to detect interference, whether from the neighboring IAPs or
from non-Wi-Fi devices such as microwaves and cordless phones.
By default, spectrum monitoring is performed on a higher band of the 5 GHz radio.
You can configure an IAP to function as a stand-alone spectrum monitor by using the Instant UI or the CLI.
In the Instant UI
To convert an IAP to a spectrum monitor:
1. In the Access Points tab, click the IAP that you want to convert to a spectrum monitor.
2. Click the edit link.
