Adaptive AP
10-7
To review a sample AAP configuration, see Sample Switch Configuration File for IPSec and
Independent WLAN on page 10-20.
10.1.10 Adaptive AP Switch Failure
In the event of a switch failure, an AAP's independent WLAN continues to operate without disruption.
The AAP attempts to connect to other switches (if available) in background. Extended WLANs are
disabled once switch adoption is lost. When a new switch is discovered and a connection is secured,
an extended WLAN can be enabled.
If a new switch is located, the AAP synchronizes its configuration with the located switch once
adopted. If Remote Site Survivability (RSS) is disabled, the independent WLAN is also disabled in the
event of a switch failure.
10.1.11 Remote Site Survivability (RSS)
RSS can be used to turn off RF activity on an AAP if it loses adoption (connection) to the switch.
10.1.12 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 300 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
RSS State Independent WLANs Extended WLANs
RSS Enabled WLAN continues beaconing WLAN continues beaconing but AP does allow
clients to associate on that WLAN
RSS Disabled WLAN stops beaconing WLAN stops beaconing
NOTE For a dependant AAP, independent WLANs continue to beacon for three
days in the absence of a switch.
