Management frames such as beacons, and probe and association requests and responses,
consume airtime that might otherwise be used to transmit user data. Configure the
following settings to minimize management traffic by using higher data rates, and
suppressing and reducing probe and association responses under certain
circumstances.
Note
Use caution when configuring
radio optimization settings. When device configuration limits specific clients,
there is a risk that end user clients will deny access to the WLAN.
Extreme Networks provides default values for each setting.
Modifying the radio configuration is optional and should be done with
caution.
-
Go to .
-
Select an existing radio
profile, and then select
, or select 
.
-
Choose High data
rates to transmit management frames at the highest basic data
rate specified in an SSID or Low data rates to use the
lowest basic data rate.
-
Select Suppress
successive requests within the same beacon interval to enable
APs to suppress responses to repeated probe requests from the same client
received within a single beacon interval.
-
Select Suppress
response to broadcast probes by to reduce responses to broadcast
probe requests by enabling only one of several SSIDs to respond, in rotation, or
reduce responses from specific client device types.
With this feature enabled,
select a suppression method:
-
Select
Allowing only one SSID to respond at a time
to enable a single SSID to respond at a time.
-
For Reducing responses to
certain client device types select the add icon to add a
new MAC OUI.
Note
The suppression setting is disabled by default when high-density WLAN
optimization is enabled.
-
Enable Band Steering and select a mode from the
menu.
-
Use the slider to set the Allowed percentage distribution of 2.4 and
5.0 GHz clients.
-
Enable Client Load Balancing and configure the threshold
settings.
Table 1. Load balance clients based on
| Airtime |
Number of clients |
Ignore probe and association requests per device when
threshold exceeds:
- CRC Error Rate
- RF Interference
- Average Airtime Per Client

Ignore probe and association requests from clients
associated with other Extreme Networks devices until:
- Anchor Period Elapses
- Query neighbors about client load every

Enable Radio Load Balancing and specify the
Number of Connection Attempts.
-
Enable Weak Signal Probe Request Suppression and specify
the Signal-to-Noise Threshold in dB.
-
Enable Safety Net and
specify the time elapse, in seconds or minutes, before a device again responds
to association requests after an overload incident.
