Adaptive AP
If a new controller is located, the AAP synchronizes its configuration with the located controller once
adopted. If Remote Site Survivability (RSS) is disabled, the independent WLAN is also disabled in the
event of a controller failure.
Remote Site Survivability (RSS)
RSS can be used to turn off RF activity on an AAP if it loses adoption (connection) to the controller.
RSS State
Independent WLANs
RSS Enabled
WLAN continues beaconing
RSS Disabled
WLAN stops beaconing
NOTE
For a dependant AAP, independent WLANs continue to beacon for three days in the absence of a
controller.
Adaptive Mesh Support
An AAP can extend existing mesh functionality to a controller managed network. All mesh APs are
configured and managed through the wireless controller. APs without a wired connection form a mesh
backhaul to a repeater or a wired mesh node and then get adopted to the controller. Mesh nodes with
existing wired access get adopted to the controller like a wired AAP.
Mesh AAPs apply configuration changes 300 seconds after the last received controller configuration
message. When the configuration is applied on the Mesh AAP, the radios shutdown and re-initialize
(this process takes less than 2 seconds), forcing associated MUs to be deauthenticated and the Mesh link
will go down. MUs are able to quickly associate, but the Mesh link will need to be re-established before
MUs can pass traffic. This typically takes about 90 to 180 seconds depending on the size of the mesh
topology.
NOTE
When mesh is used with AAPs, the "ap-timeout" value needs to be set to a higher value (for example, 180
seconds) so Mesh AAPs remain adopted to the controller during the period when the configuration is applied and
mesh links are re-established.
For an overview of mesh networking and how to configure an Access Point to support mesh, see
