Remote Site Survivability (Rss) - Brocade Communications Systems RFS6000 System Reference Manual

Adaptive AP Overview
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 Enabled
RSS Disabled
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 a Mobility 5181's 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 180 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 Clients to be
deauthenticated and the Mesh link will go down. Clients are able to quickly associate, but the Mesh
link will need to be re-established before Clients 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.
