Hybrid APs Using Mode-Aware ARM
If a radio is configured as a hybrid AP and that AP is enabled with mode-aware ARM, the hybrid AP can change
to an Air Monitor (or AM) if too many APs are detected in the area. If the ARM feature changes a hybrid AP to an
Air Monitor, that AM does not provide spectrum data after the mode change. The AM unsubscribes from any
connected spectrum analysis client, and sends a log message warning about the change. If mode-aware ARM
changes the AM back to an AP, the hybrid AP does not automatically resubscribe back to the spectrum analysis
client. The hybrid AP must manually resubscribed before it can appear in the client’s spectrum monitors
page.
Creating Spectrum Monitors and Hybrid APs
Each switch can support up to 22 active WebUI connections to spectrum monitor or hybrid AP radios. If you
plan on using spectrum monitors or hybrid APs as a permanent overlay to constantly monitor your network,
you should create a separate AP group for these devices. If you plan on temporarily converting campus APs to
spectrum monitors, best practices are to use the spectrum local override profile to convert an AP to a spectrum
monitor.
This section describes the following tasks for converting regular APs into hybrid APs or spectrum monitors.

Converting APs to Hybrid APs
You can convert a group of regular APs into a hybrid APs by selecting the spectrum monitoring option in the
AP group’s 802.11a and 802.11g radio profiles. Once you have enabled the spectrum monitoring option, all
APs in the group that support the spectrum monitoring feature start to function as hybrid APs. If any AP in the
group does not support the spectrum monitoring feature, that AP continues to function as a standard AP,
rather than a hybrid AP.
The spectrum monitoring option in the 802.11a and 802.11g radio profiles only affects APs in ap-mode. Devices in
am-mode (Air Monitors) or sm-mode (Spectrum Monitors) are not affected by enabling this option.
If you want to convert an individual AP (and not an entire AP group) to a hybrid AP, you must create a new
802.11a or 802.11g radio profile, enable the spectrum monitoring option, then reassign that AP to the new
profile. For additional information see Creating and Editing Mesh High-Throughput SSID Profiles on page 618
for details on how to create a new 802.11a/g radio profile, then assign an individual AP to that profile.
If the spectrum local-override profile on the switch that terminates the AP contains an entry for a hybrid AP radio,
that entry overrides the mode selection in the 802.11a or 802.11g radio profile, and the AP operates as a spectrum
monitor, not as a hybrid AP. You must remove any spectrum local override for an AP to allow the device to operate as
a hybrid AP. For further details on editing a spectrum local override, see Converting an Individual AP to a Spectrum
Monitor on page 755.
In the WebUI
Follow the procedure below to convert a group of APs to hybrid mode via the WebUI.
1. Navigate to the Configuration > Wireless > AP Configuration window. Select the AP Group tab.
2. Click Edit by the name of the AP group you want to convert to hybrid APs.
3. Under the Profiles list, expand the RF Management menu.
4. To enable a spectrum monitor on the 802.11a radio band, select the 802.11a radio profile menu.
