5. Under the Advanced tab of the Profile Details pane, select Traffic steering from WLANto cellular to
enable this feature, or uncheck the Traffic steering from WLANto cellular check box to disable this
feature.
6. Click Apply.
In the CLI
Use the following command to enable traffic steering via the command-line interface:
(host)(config) #wlan ssid <profile> traffic-steering
Spectrum Load Balancing
The spectrum load balancing feature helps optimize network resources by balancing clients across channels,
regardless of whether the AP or the switch is responding to the wireless clients' probe requests. The switch uses
the ARM neighbor update messages that pass between APs and the switch to determine the distribution of
clients connected to each AP's immediate (one-hop) neighbors. This feature also takes into account the
number of APs visible to the clients in the RF neighborhood, and can factor the client’s perspective on the
network into its coverage calculations.
The switch compares whether an AP has more clients than its neighboring APs on other channels. If an AP’s
client load is at or over a predetermined threshold as compared to its immediate neighbors, or if a neighboring
Alcatel-Lucent AP on another channel does not have any clients, load balancing will be enabled on that AP.
When an AP has the spectrum load balancing feature enabled, the AP will send an association response with
error code 17 to new clients trying to associate. If the client receiving the error code tries to associate to the AP
a second time, it will be admitted. If a client is rejected by two APs in a row, it will be admitted by any AP on its
third try. Note that the load balancing feature only affects the association of new clients; this feature does not
reject or attempt to balance clients that are already associated to the AP.
Spectrum load balancing is disabled by default, and can be enabled for 2.4G traffic through an 802.11g profile
or for 5G traffic through an 802.11a RF management profile. The spectrum load balancing feature also
requires that the 802.11a or 802.11g RF management profiles reference an ARM profile with ARM scanning
enabled.
The spectrum load balancing feature available in AOS-W 3.4.x and later releases completely replaces the
AP load balancing feature available earlier versions of AOS-W. When you upgrade from an older release to AOS-W
3.4.x or later, you must manually configure the spectrum load balancing settings, as you can lo longer use the AP
load balancing feature, and any previous AP load balancing settings will not be preserved.
For details on modifying 802.11a or 802.11g RF management profiles, refer to RF Management on page 558 .
Reusing Channels to Control RX Sensitivity Tuning
In some dense deployments, it is possible for APs to hear other APs on the same channel. This creates co-
channel interference and reduces the overall usage of the channel in a given area. Channel reuse enables
dynamic control over the receive (Rx) sensitivity to improve spatial reuse of the channel.
The channel reuse feature applies to non-DFS channels only. It is internally disabled for DFS channels and is does not
affect DFS radar signature detection.
You can configure the channel reuse feature to operate in either of the following three modes; static, dynamic
or disable. (This feature is disabled by default.)
