Remote Site Survivability (RSS)

RSS can be used to turn off RF activity on an AAP if it loses adoption (connection) to the switch.

NOTE

For a dependant AAP, independent WLANs continue to beacon for three days in the absence of a
switch.

Adaptive mesh support

An AAP can extend an AP51x1's existing mesh functionality to a switch managed network. All mesh
APs are configured and managed through the wireless switch. APs without a wired connection form
a mesh backhaul to a repeater or a wired mesh node and then get adopted to the switch. Mesh
nodes with existing wired access get adopted to the switch like a wired AAP.

Mesh AAPs apply configuration changes 180 seconds after the last received switch 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 switch during the period when the configuration
is applied and mesh links are re-established.

B.1.12.1 Configuring Adaptive AP Mesh

To configure mesh support for Adaptive AP:

WLAN continues beaconing but AP does allow
clients to associate on that WLAN

RSS Disabled

WLAN stops beaconing
